Description

  The present invention relates to an image forming apparatus and a printing system, and more particularly to an image forming apparatus such as a copying machine or a multi function peripheral (MFP) and a printing system in which these are connected.

  Generally, in a copying machine or a multi-function peripheral, image data formed from a print job is transferred onto a printing paper by toner transfer and fixing. However, in the process from the printing job to printing, paper jam, out of toner, paper jam (JAM) ) When an error such as a shortage of storage capacity or an optional finisher paper jam occurs, the operation is stopped and the data being processed is held on standby.

  However, if the data being processed is held on standby when an error occurs, the execution of the next print job is likely to be hindered, and various measures are required.

  Therefore, for example, an image forming apparatus disclosed in Japanese Patent Laid-Open No. 2005-4099 (Patent Document 1) has been proposed.

  This patent document 1 describes management means for managing image formation for each job, and details of processing at the time of error occurrence, details of processing after error cancellation, or job execution being executed at the time of error occurrence regarding errors occurring during the image formation. A setting unit that sets the content of processing for each job according to the error content, and when an error occurs during image formation, the job is saved or canceled for each user or department, and is wasted Image formation is avoided.

  An image forming system disclosed in Japanese Patent Laid-Open No. 2000-115433 (Patent Document 2) has also been proposed.

  In this patent document 2, image data of a document read by a document reading unit of a master image forming apparatus is transferred from a transfer unit to a slave image forming apparatus, and the document is printed by the master image forming apparatus and the slave image forming apparatus. An image forming system that is shared by the means, and when a transfer error of the transfer means is detected, a print control means that controls to print the document after the transfer error occurs only by the master image forming apparatus. And a plurality of image forming apparatuses share the image formation when a transfer error occurs, and the image formation can be performed promptly.

  Furthermore, an image forming apparatus disclosed in Japanese Patent Laid-Open No. 11-41385 (Patent Document 3) has also been proposed.

  In Patent Document 3, when a paper empty, a paper jam, or various abnormalities occur in a digital copying machine, image data is once transferred to a memory of an external device, and then paper supply, power restoration, paper jam, and the like are performed. When the system is ready for operation due to the release of the printer, recovery of various troubles, etc., the image data is returned from the memory of the external device and printing is resumed. When an error occurs, the image data is temporarily stored in the external memory. The printer is evacuated to the apparatus so that printing can be automatically continued without any special operation when the stop state is released.

  Furthermore, a printing system disclosed in Japanese Patent Laid-Open No. 2007-94721 (Patent Document 4) has also been proposed.

In this patent document 4, after a print job is transmitted from the host to the printer, it is held in the host until a print end notification is received from the printer, and a job ID is assigned to the print job and the job is managed by the host and the printer. When printing is interrupted during printing on the printer and the printing interruption is not canceled even after a predetermined time has passed, the number of printed pages is retained and the print job is deleted so that other jobs can be processed. When printing is canceled, the previous interrupted print job is received again from the host, and printing is resumed from the next page that was printed. A large-capacity storage device and print server are required in the printer. Instead, other jobs can be executed by the printer when an error occurs.

  However, in Patent Document 1 described above, when an error occurs during image formation, job saving and cancellation processing corresponding to each user or department can be set. However, depending on the job, other connected image formations are possible. Depending on the device, the job can be executed quickly, and there is room for improvement.

  Further, in Patent Document 2, when an error occurs during transfer of image data, image formation is shared by a plurality of image forming apparatuses. However, when an error state occurs in other image forming apparatuses, job distribution is performed. Until the processing cannot be performed or the error of the other image forming apparatus is canceled, the data remains in the transfer source image forming apparatus, and the above-described problem is still not solved.

  Further, in Patent Document 3, image data is temporarily saved in an external storage device when an error occurs. Further, in Patent Document 4, a job is canceled when the error is not canceled even if a predetermined time elapses when an error occurs. In any configuration, processing of a job in which an error has occurred is interrupted, so that smooth processing of the job is not performed, and the effective use of the image forming apparatus tends to be hindered.

  SUMMARY An advantage of some aspects of the invention is that an image forming apparatus and a printing apparatus that are capable of promptly processing a job that has been interrupted due to an error even if an error occurs during the processing of the job. The purpose is to provide a system.

  In order to solve such a problem, the image forming apparatus according to the present invention processes image data formed from a print job at least on its own machine according to the content of an error that occurs during the image forming process, or on another machine. A storage unit that stores processing correspondence data for which processing correspondence is set in advance and the occurrence of the error are detected, and the print job is sent to the own machine corresponding to the detected error based on the processing correspondence data. When the discrimination unit discriminates whether to process in the other machine or the other machine, and when this discrimination unit discriminates the own machine process, the print job related to the detection error is controlled by referring to the processing corresponding data, A control unit that controls output of the print job related to the detection error to the other machine with reference to the processing-corresponding data when it is determined that the other machine process.

The image forming apparatus according to the present invention includes an error canceling unit that cancels the error state in the self-machine, and the processing correspondence that is the self-machine processing but not the self-machine processing is set in the processing correspondence data. The determination unit determines whether or not to process the print job in which the error is detected, and the control unit determines that the determination unit determines that the processing is not performed by the own unit. This is a configuration that controls execution of error cancellation in the system.

  The image forming apparatus of the present invention has a configuration in which the control unit controls output of the print job to the other machine when the other machine is connected.

  In the image forming apparatus of the present invention, the control unit checks whether or not there is an error with respect to the other machine, and controls output of the print job to the other machine when error information is not obtained. In response to an error presence / absence confirmation request, error information is output if an error has occurred, and no error information is output if no error has occurred.

In the image forming apparatus of the present invention, when there is no information indicating confidentiality in the print job, when the processing correspondence to be processed by another device is set in the processing correspondence data, the determination unit displays information indicating the confidentiality in the print job. When the control unit determines that there is no information indicating confidentiality, the print job is output to another machine .

  In the image forming apparatus according to the present invention, the processing corresponding to output the print job to a predetermined other output destination other than the output destination specified in the print job is set as the processing corresponding data. The determination unit determines whether or not to output the error-detected print job to the other output destination, and the control unit determines that the determination unit outputs the print job to the other output destination. In this case, it is possible to control the output of the print job to another output destination.

  In the image forming apparatus according to the present invention, when the processing correspondence to be processed by itself is set in the processing correspondence data when the print job has confidential information, the determination unit displays the confidential information in the print job. A configuration is also possible in which the presence or absence of the print job is determined, and when the control unit determines that the print job has confidential information, the print job is deleted.

  In the image forming apparatus according to the present invention, when the processing correspondence to be processed by itself is set in the processing correspondence data when the print job has confidential information, the determination unit displays the confidential information in the print job. A configuration is also possible in which when the control unit determines that there is no confidential information in the determination unit, the print job is stored and controlled.

  The printing system according to the present invention includes the image forming apparatuses and the image forming apparatus as the other apparatus that is connected to the image forming apparatus and prints a print job output from the image forming apparatus.

  In such an image forming apparatus and printing system according to the present invention, processing correspondence data in which processing correspondence corresponding to the content of the error is set in advance is stored in the storage unit, and the occurrence of the error is detected in the determination unit. Based on the data corresponding to the processing, it is determined whether the print job related to the detection error is to be processed by the own machine or the other machine. In addition to controlling the own machine processing of the print job related to the error, and when the discrimination unit discriminates from the other machine processing, the control unit controls the output of the print job related to the detection error to the other machine. Even if an error occurs, it is possible to quickly process the job in which the error has occurred.

In the present invention, there is an error canceling unit for canceling the error state in the own device, and when the determination unit determines that the processing is not performed by the own device, the control unit executes control to execute error cancellation in the error canceling unit. Therefore, when the print job related to the detection error is not processed on the other device side or the own device side, the print job is quickly deleted, and it is difficult to interfere with the processing of other jobs.

In the present invention, when the other machine is connected, the control unit controls the output of the print job to the other machine, so that the print job related to the detection error is promptly processed on the other machine side. Hard to interfere with job processing.

In the present invention, only when the control unit the error information other machines can not be obtained, its because outputs control a print job, it is possible to reliably handle a print job output by the other machine side.

In the present invention, when it is determined that there is no information indicating a confidential to the print job in which the determination unit is detected errors, since the controller outputs control the print job to the other machine, a information indicating the confidential printing Since the job is not printed on the other machine side, it is easy to ensure the security of the print job.

  In the present invention, when the determination unit determines that the print job is output to another output destination, the control unit outputs the print job to another output destination. Therefore, it is possible to ensure the processing of the print job in the own machine.

  In the present invention, when the determination unit determines that there is confidential information in the print job, in the configuration in which the control unit deletes the print job, the original image forming process is performed on the print job having the confidential information. If not performed, the print job is deleted, so security can be easily ensured.

  In the present invention, when the determining unit determines that there is no confidential information in the print job, the control unit stores and controls the print job. The print job is saved and can be processed later, and other processes can be easily executed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic block diagram showing an embodiment of an image forming apparatus according to the present invention. The printing system according to the present invention will be described in the course of describing the image forming apparatus.

For example, it is a multi-function machine configured to have a control unit 15 for controlling.

  A post-processing device 17 as an option for the image forming apparatus A is connected to the bus 1, and details will be described later.

  For example, in the image forming apparatus A of FIG. 2, the image reading unit 3 is arranged on the upper part of the main body case 19, and electronic image data obtained by optically reading an image from a document and performing filter processing under the control of the control unit 15. Is generated as a print job, and the generated image data is sequentially stored in the storage unit 7 for each page of the document. The internal configuration of the image forming apparatus A in FIG. 2 will be described later.

  In FIG. 1, the communication unit 5 communicates with, for example, another multifunction device (image forming apparatus) B via a known network 21 under the control of the control unit 15 (for example, TCP / IP: An interface unit that transmits a print job by simple network management protocol) and receives error information from the multi-function peripheral B.

  The storage unit 7 is, for example, a hard disk (HDD) that stores a print job from the image reading unit 3, processing correspondence data described later, and an operation program of the control unit 15.

  The operation display unit 9 is composed of, for example, a liquid crystal operation panel that also serves as a liquid crystal display unit and a touch switch operation input unit, which is disposed on the upper part of the main body case 19 of the image forming apparatus A of FIG.

  The operation display unit 9 displays the operation and operation display of the image forming apparatus A, as well as errors in the operation and operation, while selecting the printing paper that is the print medium to be printed, executing or canceling the printing, and processing correspondence data Creation and change processing, and other conventionally known display input functions, which are controlled by the control unit 15.

  The printing unit 11 is a print engine that is disposed in the main body case 19 of the image forming apparatus A shown in FIG. 2 and that prints image data on a printing sheet in monochrome or color and discharges it under the control of the control unit 15. Details will be described later.

  The determination unit 13 monitors the image reading unit 3, the communication unit 5, the storage unit 7, the operation display unit 9, the printing unit 11, and the post-processing device 17 under the control of the control unit 15, and image data formed from the print job A process corresponding to the content of the detected error is detected by detecting an error occurring in the process of transferring and fixing the image to the printing paper and discharging the sheet, that is, in the process of forming an image, and referring to the processing corresponding data stored in the storage unit 7 It has a function of determining whether or not to implement a response.

  For example, as shown in FIG. 3, the processing correspondence data indicates whether another image forming apparatus (multifunction machine: other machine) B is connected to the image forming apparatus (own machine) A of the present invention via a network 21. No, whether the print job to be output contains confidential information (confidential data), and there is a predetermined other output destination, for example, a discharge tray 39, 41 described later in FIG. Depending on the contents of “Error 1”, “Error 2”, and “Error 3” of the print job, the processing corresponding to the own machine A or the other machine B behaves as “1” to “7”. ”.

  The contents of the error include, for example, “Error 1” such as paper jam, out of toner or insufficient storage capacity of the storage unit 7 (memory full), “Error 2” such as option error (post-processing device error: finisher error), coin vendor ( There is “Error 3” such as a lack of charges while using Coin vender.

  As the behavior on the own device A, the behavior “1” does not perform any processing other than error cancellation or cancellation as the processing on the own device A, and the behavior “2” processes the job (print job) on the own device A, The behavior “3” leaves the job (print job) to processing on the other device B, the behavior “4” is output to another output destination by the own device A, and the behavior “5” is output to another output destination by the own device A. In the state where no other exists, the behavior “6” stores image data in the storage unit 7 of the own device A, and the behavior “7” is a process of deleting the job (print job) by the own device A.

  The determination unit 13 has a function of performing the following determination according to the processing correspondence data.

  As an example, when an “error 2” (finisher error) that needs to be discharged to the discharge trays 39 and 41 occurs when the later-described discharge tray 31 is blocked, the other machine B is connected and the print job Includes information indicating confidentiality, and if there is another output destination in the own machine A, it is determined that the own machine A processes the print job in accordance with the behavior “2”, and the own machine in accordance with the behavior “4”. In A, it is determined that the data is output to another output destination.

  If another output destination does not exist in own device A, it is determined that the print job is processed by own device A according to behavior “2”, and it is determined that there is no other output destination of own device A according to behavior “5”. At the same time, it is determined that the print job is to be deleted according to the behavior “7”.

  If the other machine B is connected and the print job does not contain confidential information, and if the own machine A has an output destination, the print job is processed by the own machine A according to the behavior “2”. In response to the behavior “4”, it is determined that the own device A outputs to another output destination. On the other hand, if the own device A does not have an output destination, the other device B performs processing according to the behavior “3”. It is determined to leave it to you.

  When the other machine B does not exist or is not connected and the print job includes confidential information and the own machine A has another output destination, the own machine A follows the behavior “2”. It is determined that the print job is to be processed, and it is determined that the own apparatus A performs output processing to another output destination according to the behavior “4”.

  On the other hand, when the output destination does not exist in the own device A, it is determined that the print job is processed by the own device A according to the behavior “2”, and it is determined that there is no other output destination of the own device A according to the behavior “5”. In accordance with the behavior “7”, it is determined that the print job is to be deleted.

  If the print job does not contain confidential information and there is another output destination in the own device A, it is determined that the print job is to be processed in the own device A according to the behavior “2”, and the behavior “4”. Accordingly, it is determined that the own device A performs output processing to another output destination.

  If there is no output destination in the own device A, it is determined that the print job is processed in the own device A according to the behavior “2”, and it is determined that there is no output destination of the own device A according to the behavior “5”. In accordance with the behavior “6”, it is determined that the image data is stored in the memory of the own device A.

  If “error 3” is detected, it is determined according to the behavior “1” that processing other than error cancellation or cancellation is not performed.

  The control unit 15 includes a CPU, a memory unit that stores an operation program of the CPU, and an input / output interface (none of which are shown), and the image reading unit 3, the communication unit 5, the storage unit 7, and the operation display described above. This unit controls the unit 9, the printing unit 11, and the determination unit 13, and has the following functions.

  The control unit 15 has a function of controlling the corresponding processing correspondence with reference to the above-described processing correspondence data according to the discrimination of the discrimination unit 13 for the print job related to the detection error.

  That is, if the determination unit 13 determines that the behavior is “1”, the control unit 15 does not perform any processing other than error cancellation or cancellation. If it determines that the behavior is “2”, the control unit 15 controls the processing of the print job by itself. If it is determined that the behavior is “3”, output control of the print job from the communication unit 5 to the other device B is performed, and the processing is left to the other device B.

  If the determination unit 13 determines that the behavior is “4”, the control unit 15 performs output control of the print job to another output destination. If the determination unit 13 determines that the behavior is “5”, the control unit 15 performs output control to the output destination by the own device A. If it is determined as “6”, the image data is stored and controlled in the storage unit 7 of its own device A. If it is determined as “7”, the print job in the storage unit 7 is deleted.

  The control unit 15 also functions as a function for deleting the print job if the determination unit 13 determines that the behavior is “7”, that is, an error canceling unit.

  As will be described later, the control unit 15 confirms the presence or absence of an error with respect to the multifunction device B, and when error information is obtained from the multifunction device B, even if it is determined that the behavior is “3”, the print job Is output from the communication unit 5 to the multifunction device B, and when error information cannot be obtained, the print job is output to the multifunction device B.

  The post-processing device 17 operates under the control of the control unit 15 and is an option for punching, stacking a plurality of sheets, stapling, or bending the printing paper discharged from the printing unit 11. Has a finisher processing function.

  Although not shown, the other multifunction device B is configured to include an image reading unit, a communication unit, a storage unit, an operation display unit, a printing unit, a control unit that controls these, and the like, similar to the image forming apparatus A. In response to an error presence confirmation request from the image forming apparatus A, the error information is output to the image forming apparatus A if an error has occurred, and the error information is not output if no error has occurred. Yes.

  FIG. 2 is a schematic configuration diagram showing the internal configuration of the image forming apparatus A and the post-processing apparatus 17 described above.

  In FIG. 2, in addition to a plurality of paper feed cassettes 23, a lower part of the main body case 19 of the image forming apparatus A has image data while secondary feeding paper sheets that are primarily fed from these paper feed cassettes 23. The above-described printing unit 11 including the transfer fixing unit 25 for transferring and fixing the toner is disposed.

  The printing unit 11 can perform monochrome or color printing by switching setting, and also includes a reversing conveyance unit 27 that reverses the front and back of the printing paper on which the image is transferred and fixed on one side and returns it to the transfer fixing unit 25.

  The image reading unit 3 and the operation display unit 9 described above are arranged on the upper part of the main body case 19, and the communication unit 5, the storage unit 7, the determination unit 13, and the control unit 15 are arranged at appropriate positions inside the main body case 19. An electronic circuit is formed and arranged.

  As described above, the post-processing device 17 is arranged to be connected to the paper discharge unit 29 side of the printing unit 11.

  The post-processing device 17 includes a paper discharge tray 31 for collecting printing paper discharged from the printing unit 11, an intermediate stack unit 33, a bending processing unit 35, and the like.

  Reference numeral 37 in the post-processing device 17 is a branch lever that determines whether the printing paper from the printing unit 11 is discharged to the paper discharge tray 31 or the intermediate stack unit 33, and is controlled by the post-processing control unit 17. Reference numerals 39 and 41 denote discharge trays for printing paper from the intermediate stack portion 33 and the bending processing portion 35.

  In the present invention, for convenience, the discharge tray 31 is described as “original output destination”, and the discharge trays 39 and 41 are described as “different output destinations”.

  Next, the operation of the image forming apparatus according to the present invention will be described with reference to the flowchart of FIG.

  When the program is started, in step S1, for example, the printing unit 11 executes print processing of a print job based on the image data, and in step S2, the determination unit 11 determines whether an error has occurred, and no error occurs. If step S2 is NO, the printing unit 11 executes print processing of the print job in step S3, outputs the printed paper from the discharge tray 31 that is the original output destination, and ends the print job. Is reset.

  For example, if error 1 such as a paper jam occurs in the printing unit 11 and step S2 is YES, the determination unit 11 confirms the processing correspondence with reference to the processing countermeasure data in FIG. 3 in step S4, and step S5. The discriminating unit 11 discriminates errors.

  If the error determination is “1”, the process proceeds to step S6, where the control unit 15 determines whether or not there is an error canceling condition, and the error in the storage unit 7 is eliminated or the temperature of the fixing unit in the printing unit 11 decreases. If the error canceling condition such as removal of the post-processing device 17 is satisfied, Step S6 becomes YES, and the processing returns to Step S1 without executing any processing.

  When the determination unit 11 determines that the behavior is “3” in step S5, the process proceeds to step S7, where the control unit 15 controls the output of the print job to the other device B, and ends the execution of the printing process to the other device B. In this example, error information from the other device B is not considered.

  If the determination unit 11 determines that the behavior is “2” in step S5, the process proceeds to step S8, where the determination unit 11 determines the error content. If the determination unit 11 determines that the behavior is “4”, the process proceeds to step S9 and the control unit 15 performs printing. The job is executed, output control is performed to another output destination, for example, the paper discharge tray 39 or 41, and the process ends.

  In this example, when an error occurs in the post-processing device (finisher) 17 and all the stages of the paper discharge tray 31 cannot be used, or when the previous printed matter remains, the printed paper is transferred to the paper discharge tray 39, An example of outputting to 41 is conceivable.

  If the determination unit 11 determines that the behavior is “5” in step S8, the process proceeds to step S10, and the control unit 15 determines whether the error waiting period has elapsed. If the period has elapsed and step S10 becomes YES, the process proceeds to step S11. The determination unit 11 confirms the error content, and determines the error content in the subsequent step S12.

  If the determination unit 11 determines that the behavior is “6” in step S12, the control unit 15 stores and controls the print job in the storage unit 7 in step S13 and ends. If the determination unit 11 determines that the behavior is “7”, the process proceeds to step S14. Then, the control unit 15 deletes the print job from the storage unit 7 and ends.

  In such an image forming apparatus according to the present invention, processing is performed at least by the image forming apparatus (own apparatus) A or another image forming apparatus (other apparatus) corresponding to the content of an error that occurs in the processing process of the print job. ) A storage unit 7 for storing processing correspondence data for which processing correspondence is set in advance is detected, and the occurrence of the error is detected. Based on the processing correspondence data, a print job corresponding to the error is detected. A discrimination unit 13 for discriminating whether the processing is performed by the own device A or the other device B, and when the discrimination unit 13 determines that the processing is the own device, the print job related to the detection error is referred to by referring to the processing correspondence data. And a control unit 15 that controls the output of the print job related to the detection error to the other machine with reference to the process-corresponding data when the own machine process is controlled and determined as the other machine process.

  For this reason, when an error occurs during the processing of a print job, it is determined whether the processing is performed by the own device A or the other device B depending on the error content, and the error state can be released early, and an error occurs. It is difficult for the print job to remain in the image forming apparatus A, the memory used for the print job is released, and prompt processing of other jobs is facilitated.

  In addition, when the determination unit 13 has an error canceling unit (control unit) 15 that cancels the error state in the own device A and the processing is not performed in the own device A, the error canceling unit (control unit) 15 Since the error cancellation of the print job is executed, when the print job related to the detection error is not processed on the other machine B side or the own machine A side, the print job is quickly deleted. It is hard to disturb processing.

  In addition, since the print job is output to the other machine B when the other machine B is connected, the print job related to the detection error is promptly processed on the other machine B side, and similarly the processing of other jobs is hindered. If the print job is output when an error of the other device B is not detected, the output print job can be reliably processed on the other device B side.

  Furthermore, if it is determined that there is no confidential information in the print job in which an error is detected, if the print job is output to the other machine B, the print job with the confidential information is printed on the other machine B side. Since it is not processed, the security of the print job is also ensured.

  When it is determined that the print job is output to another output destination, the print job is output to the other output destination. Therefore, even if the original print processing is difficult, the print job is separated in the own device A. Can be processed at the output destination.

  In addition, when it is determined that the print job has confidential information in the own device A, the print job is deleted. Therefore, when the original print processing is not performed for the print job having the confidential information, the print job is deleted. Similarly, it is easy to ensure security.

  Furthermore, since the print job is stored in the own machine A when it is determined that there is no confidential information, the print job is saved in the own machine even if the original print process is difficult, Other processes can be executed, and the process in the own machine A after the error is canceled becomes possible.

  The image forming apparatus A of the present invention is not limited to the configuration in which the “original output destination” is the discharge tray 31 or the “separate output destination” is the discharge trays 39 and 41 as described above. A configuration in which “original output destination” and “separate output destination” are internal output destinations of the image forming apparatus A itself is possible.

  By the way, in the image forming apparatus A of the present invention, a print job to be output is output with a name or ID indicating the image forming apparatus A that is a transmission source, and these images are output in the image forming apparatus B that is a reception destination. The name and ID indicating the forming apparatus A may be printed. For example, the control unit 15 may have a function of assigning a name and ID, and the image forming apparatus B may be configured to print.

  In such a configuration, since the transmission source is printed and displayed on the printed matter, there is an advantage that it is easy to understand where the original is from the printing instruction.

  The printing system according to the present invention includes the above-described image forming apparatus A and the image forming apparatus B as another machine that prints a print job related to the detection error output from the image forming apparatus A. The same effect as that of the image forming apparatus A can be obtained.

A control unit that controls output of the print job related to a detection error to the other device;
An error canceling unit for canceling the error state in the machine;
Comprising
Whether the determination unit performs processing of the print job in which an error is detected when the processing corresponding to the processing of the own device and not processing by the own device is set in the processing correspondence data. If there is no information indicating confidentiality in the print job and the processing correspondence to be processed by the other device is set in the processing correspondence data, the information indicating the confidentiality in the print job in which an error has been detected Determine the presence or absence,
When the other device is connected, the control unit checks whether there is an error with respect to the other device, and when error information is not obtained, controls the output of the print job to the other device, and the error information When it is obtained, the output of the print job is not controlled to the other machine, and the error information is output if an error has occurred in response to an error confirmation request, and the error information if the error has not occurred. Is output , and when the determination unit determines that there is no information indicating the confidentiality, the print job is output to the other device, and the determination unit determines that the processing is not performed on the own device. The image forming apparatus controls execution of the error cancellation in the error canceling unit. The determination unit is determined as the self-process, and when the processing correspondence for outputting the print job to a predetermined other output destination other than the output destination specified in the print job is set in the processing correspondence data, It is determined whether or not the error-detected print job corresponds to output to the another output destination, and the control unit determines that the print job corresponds to output corresponding to the other output destination. The image forming apparatus according to claim 1, wherein output control is performed to the separate output destination. When the processing correspondence to be processed by itself is set in the processing correspondence data when there is information indicating confidentiality in the print job, the determination unit stores the information indicating the confidentiality in the print job in which an error is detected. 2. The image forming apparatus according to claim 1, wherein presence / absence is determined, and the control unit deletes the print job when the determination unit determines that the print job includes information indicating the confidentiality. When the processing correspondence to be processed by itself is set in the processing correspondence data when there is information indicating confidentiality in the print job, the determination unit stores the information indicating the confidentiality in the print job in which an error is detected. The image forming apparatus according to claim 1, wherein the presence or absence is determined, and the control unit stores and controls the print job when the determination unit determines that there is no information indicating the confidentiality in the print job. 5.
