Detailed ways

In order to better understand the technical solutions of the present specification, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

It should be clear that the described embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

Terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the description. As used in the embodiments of the present invention and the appended claims, the singular forms "a", "said" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

Fig. 1 is a flowchart of a control parameter matching method provided by an embodiment of the present invention. The method can be applied to an image forming device, and the image forming device includes but is not limited to a printer, a copier, a fax machine, a scanner, and an all-in-one machine that integrates functions such as printing, copying, faxing, and scanning, etc., and its functions are Print images or text on imaging media. As shown in Figure 1, the method may include:

Step 101 , after the image forming apparatus is started, if it is determined that the image forming apparatus has stored a first control parameter of the laser scanning unit, then the operation of the laser scanning unit is controlled based on the first control parameter.

After the image forming device is started, it can check the flag bit information related to the control parameters, and determine whether the first control parameter of the laser scanning unit has been stored according to the specific value of the flag bit information. Optionally, before the laser scanning unit is installed for the first time, the image forming device does not store control parameters, and the flag bit information can be set to one of the second preset values, such as a null value or a negative number. After the control parameters are successfully matched, the flag bit information can be set to The value of the bit information is set to one of the first preset values, such as positive numbers such as 1, 2 or 0. The expression form of the flag bit information is not limited, and it can also be set as letters or other symbols. For example, when the control parameters are not stored, the flag bit information is set to A; when the control parameters are stored, the flag bit information is set to B, C, and Other letters; or, when the control parameter is not stored, the flag bit information is set to 0x01, and when the control parameter has been stored, the flag bit information is set to 0x02, 0x03 and other values. The image forming apparatus stores the control parameter that is successfully matched for the first time as the first control parameter, and modifies the flag bit information to a first preset value corresponding to the first control parameter. After the image forming apparatus is restarted, it is detected that the flag bit information is the first preset value, and it can be determined that the first control parameter has been successfully matched and stored before this startup. The image forming device directly acquires the pre-stored first control parameters, and controls the operation of the laser scanning unit based on the first control parameters. In a specific embodiment, if the current LSU is a pentaprism type, the flag bit information may be set to 1, and if the current LSU is a quadrangle prism type, the flag bit information may be set to 2.

Step 102, during the operation of the laser scanning unit, determine whether the first control parameter matches the laser scanning unit according to the line synchronization signal parameters of the laser scanning unit.

The parameter of the horizontal synchronization signal in this embodiment of the present invention may include at least one of the number and period of the horizontal synchronization signal. The laser scanning unit can be as shown in FIG. 2 , and specifically includes: a light emitting control circuit 201, a laser diode 202, a focusing lens 203, a polygon mirror motor 204, a focusing lens 205, a reflector 206, a reflector 207, a focus lens 208, and a focus lens 209 and line sync sensor 210. The light emission control circuit 201 can control the laser diode 202 to emit light beams. The light beams are converted into parallel light by the focusing lens 203 and reach the polygon mirror motor 204. The polygon mirror motor 205 reflects the light beams. After the light beams pass through the focusing lens 205, they illuminate two directions. The reflector 206 reflects the light beam to the focus lens 209, which focuses the parallel light and irradiates it to the line synchronous sensor 210; the focus lens 208 focuses the light beam, which is reflected by the reflector 207 to the surface of the photosensitive drum for scanning. After the laser scanning unit is running, the polygon mirror motor rotates to change the angle of the reflected light beam. Every time it turns one side, one line can be scanned on the photosensitive drum. The time used to scan one line is the line synchronization signal period. The reflected light of the polygon mirror motor 205 will reach the line synchronization sensor 210 in addition to the photosensitive drum. The line synchronization sensor 210 can determine the actual line synchronization signal period of the laser scanning unit. The first control parameter records the preset line synchronization signal period, the image forming apparatus can compare the actual period of the line synchronization signal with the period of the preset line synchronization signal, so as to determine whether the first control parameter matches the laser scanning unit. Specifically, if the difference between the actual line synchronization signal period and the preset line synchronization signal period does not exceed the first threshold, it can be determined that the first control parameter matches the laser scanning unit, otherwise it is determined that the first control parameter does not match the laser scanning unit .

Step 103, if not, re-execute the control parameter matching process, determine a second control parameter matching the laser scanning unit, and control the operation of the laser scanning unit based on the second control parameter.

If the type of the laser scanning unit is changed before the image forming apparatus is started, the previously stored first control parameter may not match the current laser scanning unit, so the control parameter matching process needs to be executed again. The control parameters mainly include: LED type, resolution, printing amplitude, effective scanning angle, number of polygonal mirrors, line synchronization signal cycle, line scanning frequency, time for polygonal mirror motor to rotate one circle, polygonal mirror motor speed, angle between mirrors And scan effective utilization, etc. Among them, the number of polygon mirrors, the period of the line synchronization signal and the rotation speed of the polygon mirror motor are the main influencing factors. The number of polygon mirrors of different types of laser scanning units may be different. When the rotation speed of the polygon mirror motor is the same, the period of the line synchronization signal and the number of polygon mirrors Inversely proportional. Relevant formulas include: rotation speed of the polygon mirror motor=period of the line synchronization signal*60/number of polygon mirrors. The image forming device can obtain a variety of pre-configured control parameters, each control parameter includes a different rotation speed of the polygon mirror motor and a corresponding period T1 of the line synchronization signal, and then control the motor of the laser scanning unit based on the rotation speed of the polygon mirror motor of any control parameter Run, and determine the actual line synchronization signal period T2 of the current laser scanning unit, if the difference between T1 and T2 does not exceed the first threshold, then determine the current control parameter as the second control parameter matching the laser scanning unit, if T1 and T2 If the difference exceeds the first threshold, other control parameters are switched for matching. After the matching is successful, the image forming device will delete the previously stored first control parameter and store the successfully matched control parameter as the second control parameter, and at the same time modify the flag information, for example, modify the flag information from 1 to 2.

In one embodiment, in step 101, if after the image forming device is started, it is detected that the flag bit information is a negative number (LSU is installed for the first time) or other second preset values, the control parameter matching process is directly executed, and after the matching is successful, The parameter matched this time is stored as the second control parameter, and the flag bit information is modified to be a positive number or other first preset value.

In the existing technical solutions, a special memory chip is usually set up to store all the previously matched control parameters and flag bit information associatively, for example, flag bit 1-type control parameters, flag bit 2-type B control parameters, Flag bit 3—C control parameters, etc., LSU identity identification is performed each time the image forming device is started, and corresponding control parameters are acquired. In the embodiment of the present invention, the image forming device only saves the control parameters and flag bit information that are currently successfully matched. For example, before the type A control parameters are successfully matched, the stored flag bit 1-type A control parameters, before the type B control parameters are successfully matched, Delete flag bit 1-type A control parameters, and store flag bit 2-type B control parameters. In this way, a dedicated chip may not be provided to store associated information, saving space.

In the embodiment of the present invention, after the image forming device is started, the operation of the laser scanning unit is directly controlled based on the stored first control parameters, which reduces the waiting time caused by parameter matching; secondly, if the first control parameters do not match, then re-execute Control the parameter matching process, and delete the first control parameter after the matching is successful, because there is no need to save the association relationship between the flag bit information and the corresponding control parameter, saving storage space.

FIG. 3 is a flowchart of another control parameter matching method provided by an embodiment of the present invention. As shown in Figure 3, the method may include:

Step 301, judging whether the control parameter has been stored according to the flag bit information.

After the image forming device is started, first judge the flag bit information, if it is detected that the flag bit information is the second preset value (such as the flag bit information is a positive number), it can be determined that the matching has been successful and the control parameters have been stored before, and enter In step 307, if the flag bit information is the first preset value (such as a negative number), it can be determined that no control parameter has been stored before, and the process goes to step 302.

Step 302, run the LSU with type A control parameters.

If the control parameters are not stored, the control parameters are matched sequentially, and one control parameter is selected to run the LSU.

Step 303, acquiring the actual period of the line synchronization signal of the current LSU.

Step 304, judging whether the actual period of the line synchronization signal matches the period of the preset line synchronization signal recorded in the current control parameter.

The control parameter currently in the matching process records the preset line synchronization signal period, and if the error between the actual line synchronization signal period of the LSU and the preset line synchronization signal period is small, it can be determined that the control parameter matches the LSU. Specifically, an error threshold may be set in advance, and if the difference between the actual period of the horizontal synchronization signal and the period of the preset horizontal synchronization signal does not exceed the error threshold, it is determined that the current control parameter matches the LSU.

Step 305, switching control parameters of type B (C, D, E) for matching.

If the matching of the current control parameter fails, other control parameters are switched for matching.

Step 306, storing type A control parameters and flag bit information.

If the matching is successful, the image forming apparatus stores the current control parameters, and sets the flag bit information as a positive number, and if the matching fails, sets the flag bit information as a negative number.

In a specific embodiment, the image forming device will set different flag bit information and report the reason according to the cause of the matching failure. If the error is large, set the flag bit information to -2, and report that the cycle of the line synchronization signal is abnormal; if all control parameters If they do not match, set the flag bit information to -1, and report LSU identification failure; if the motor parameters are abnormal, causing the motor to start unstable, set the flag bit information to -3, and report the motor abnormality, the user can replace the motor before matching .

Step 307, run the LSU based on the matched control parameters.

During the operation of the LSU, the image forming device will still detect the period of the synchronization signal, and if the period of the line synchronization signal is found to be abnormal, it will perform the matching process of the control parameters again.

In the actual matching process, the image forming device can judge whether to perform matching according to whether the LSU rotates. The rotation indicates that the matching is in progress. After the LSU rotates, it is normally ready to indicate that the matching is successful. If the LSU is broken and does not rotate, the period of the line synchronization signal cannot be matched, and the image is formed. The device will report an error, usually 2 times.

In one embodiment, in order to prevent the control parameter matching process from affecting the overall timing of the image forming apparatus, a separate thread may be started to complete the matching process before the main thread is started. In order to reduce the loss of the motor, the control parameter with the smallest motor speed can be selected first for matching. If the matching fails, other control parameters are switched according to the order of the motor speed from small to large.

In the embodiment of the present invention, if it is determined that the control parameters have been stored after the image forming device is started, the control parameters are directly acquired to control the operation of the LSU, and whether the control parameters match is judged according to the period of the line synchronization signal during operation. The type identification (control parameter matching) can reduce the waiting time. If it is determined that the control parameters are not stored, the LSU is operated based on different control parameters, and matching is performed according to the actual period of the line synchronization signal. A line synchronization sensor is installed inside the LSU to determine the actual period of the line synchronization signal.

The judgment module 420 determines the actual line synchronization signal period of the laser scanning unit during the operation of the laser scanning unit; if the difference between the actual line synchronization signal period and the preset line synchronization signal period recorded in the first control parameter does not exceed the first threshold, Then it is determined that the first control parameter matches the laser scanning unit, otherwise it is determined that the first control parameter does not match the laser scanning unit.
