The scanning control unit also comprises position detection for controlling the position sensor to detect the position of the scanning unit, the width of paper, the detection for opening the box cover, the detection for ADF paper feeding and the like.
In a possible implementation, the sub-control system 401 may further comprise a unit module or the like related to performing other functional operations, for example, may comprise a power management unit for power supply of the sub-control system. Similarly, the sub-control system 401 may further include related unit modules for performing other functional operations, which are not described herein, and the unit modules included in the sub-control system 401 are not limited in the embodiment of the present invention.

The sub-control system 401 includes a second memory unit 404 and a memory bandwidth thereof, performs image processing on a scanned image in advance through the sub-control system 401, and converts the scanned image into a scanned file which can be identified by the main control system and printed or output to an external device.
Referring to fig. 5, a schematic structural diagram of another image forming apparatus according to an embodiment of the present invention is provided. The image forming apparatus 500 further includes a print engine control unit 507, a printing unit 508. The print engine control unit 507 is directly connected to the main control system 501 and isolated from the sub-control system 502 by the main control system 501, and the main control system 501 can continue to control the print engine control unit 507 to process image data to be printed when the sub-control system 502 is powered off or damaged. In other words, when the sub-control system 502 is powered off or damaged, the main control system 501 transmits print data to the print engine control unit 507, and the print engine control unit 507 controls the print unit 508 to perform a printing operation.
Specifically, as shown in fig. 5, the image forming apparatus 500 includes a main control system 501, a sub-control system 502, a scanning control unit 503, a scanning unit 504, a control panel 505, a print engine control unit 507, and a printing unit 508. Among them, the main control System 501, for example, a SoC (System on Chip), is configured as a central processing unit of the image forming apparatus 500, and receives a panel operation instruction from the control panel 505 or a scan control command from an external input. The sub-control System 502, for example, a SoC (System on Chip), receives a scan start instruction transmitted from the main control System 501, and outputs a control instruction that controls the scan control unit 503 to be able to execute a control instruction that controls the scan unit 504 to perform an image scanning operation based on the scan start instruction. The sub-control system 502 also receives the scanned image output from the scanning unit 504, and converts the scanned image into a scanned file that the main control system 501 can recognize and print or output to the external device 506. When it is necessary to perform a printing operation on the scanned image, the main control system 501 transmits print data to the print engine control unit 507, and the print engine control unit 507 controls the printing unit 508 to perform the printing operation. In addition, when the sub-control system 502 is powered off or damaged, since the print engine control unit 507 is isolated from the sub-control system 502 by the main control system 501, the main control system 501 can continue to control the print engine control unit 507 to process image data to be printed. In other words, when the sub-control system 502 is powered off or damaged, the user's printing operation is not affected.
In one possible implementation, the main control system 501 sends the print data to the print engine control unit 507 and stores the print data in the storage unit of the main control system 501, and performs the printing operation while performing the scanning operation during copy-by-copy or page-by-page copy, so that the imaging speed time can be shortened, which is beneficial for the parallel processing of high-speed printing and scanning transactions by the multifunctional integrated printer.
Referring to fig. 6, a schematic diagram of a process flow for determining whether a sub-control system is powered off or damaged is provided in an embodiment of the present invention. In step S601, the main control system determines whether the sub-control system is powered off or damaged according to feedback information provided by the sub-control system. In step S602, if the sub-control system is powered off or damaged, the main control system notifies the operation panel or the external device to prompt the user of "the scanning system is faulty but does not affect the printing operation", or otherwise prompts the scanning system to be faulty, but the printing operation may be performed, for example, the image forming apparatus without the operation panel may be represented by one or more modes such as lighting, different color lights, number of times or time of flashing the lights, etc. In step S603, the print engine control unit processes the data to be printed according to the user instruction. The user instruction is a print control instruction, and the data to be printed may be the data to be printed stored in the first storage unit, or may be a print job newly issued by the user to the main control system. In step S604, if the sub-control system is not powered off or damaged, the sub-control system can perform the scanning operation normally. In step S605, the scanning control unit scans the document image according to the user instruction. In step S606, when the user issues an operation instruction for copying or an operation instruction for printing a stored scanned document image, the flow advances to step S603. In step S603, the print engine control unit processes the data to be printed according to the user instruction. If the user does not issue an operation instruction for copying or an operation instruction for printing the stored scanned document image, the process is ended.
Referring to fig. 7, a schematic diagram of another image forming apparatus 700 according to an embodiment of the present invention is provided. The image forming apparatus 700 may include at least two sub-control systems. The sub-control System may specifically be an SoC (System on Chip), and the two sub-control systems may be the same or different. The first sub-control system 702 controls the first scanning unit 704 to perform a first image scanning operation through the first scanning control unit 703, the second sub-control system 707 controls the second scanning unit 709 to perform a second image scanning operation through the second scanning control unit 708, the first sub-control system 702 and the second sub-control system 707 are respectively electrically connected with the main control system 701, the first scanning control unit 703 is connected with the first sub-control system 702, and the second scanning control unit 708 is connected with the second sub-control system 707.
The first scan control unit 703 is a first scan engine control unit, and reads a first side of an original image according to a control instruction of an image scanning operation to obtain a first scan image. The second scan control unit 708 is a second scan engine control unit, and reads a second side of the document image according to the control instruction of the image scanning operation to obtain a second scanned image.
In one possible implementation, the first sub-control system 702 controls the first scan control unit 703 to perform a first image scanning operation, while the second sub-control system 707 controls the second scan control unit 708 to perform a second image scanning operation.
Specifically, when a user issues a panel operation instruction or control command for double-sided scanning or double-sided copying from the control panel 705 or through the external device 706, the main control system 701 simultaneously controls the first sub-control system 702 and the second sub-control system 707 to perform an image scanning operation. The first sub-control system 702 controls the first scanning unit 704 to read the first side of the document image in accordance with a control instruction of the image scanning operation through the first scanning engine control unit 703. Meanwhile, the second sub-control system 707 is controlled to control the second scanning unit 709 to read the second side of the document image in accordance with a control instruction of the image scanning operation through the second scanning engine control unit 708. After the scanning is completed, the first sub-control system 702 receives a first side of the document image, that is, a first scanned image, and the first sub-control system 702 performs image processing on the first scanned image. Meanwhile, the second sub-control system 707 receives a second side of the document image, that is, a second scanned image, and the second sub-control system 707 performs image processing on the second scanned image. Then, the first sub-control system 702 transmits the first scanned image to the main control system 701, and at the same time, the second sub-control system 707 transmits the second scanned image to the main control system 701. The main control system 701 sorts the received first scan image and second scan image in the front-back order, forms a scan file, or sends the scan file to the print engine control unit for printing operation.
In addition, when single-sided scanning is required, that is, when a user issues a single-sided scanning or single-sided copying panel operation instruction or control command from the control panel 705 or through the external device 706, the main control system 701 may control only one of the sub-control systems to perform image scanning operation, for example, control only the first sub-control system 702 to read a single-sided image of an original through the first scan engine control unit 703 according to a control instruction of the image scanning operation, or control only the second sub-control system 707 to read a single-sided image of an original through the second scan engine control unit 708 according to a control instruction of the image scanning operation.
