Detailed Description
For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step are within the scope of the present specification.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Fig. 1 is a flowchart of a control parameter matching method according to an embodiment of the present invention. The method can be applied to image forming apparatuses including, but not limited to, printers, copiers, facsimile machines, scanners, and all-in-one machines that integrate printing, copying, faxing, scanning, etc. functions of printing images or characters on an image forming medium. As shown in fig. 1, the method may include:
After the image forming device is started, the flag bit information related to the control parameter can be checked, and whether the first control parameter of the laser scanning unit is stored or not can be determined according to the specific numerical value of the flag bit information. Alternatively, before the laser scanning unit is first installed, the image forming apparatus does not store the control parameter, the flag bit information may be set to one of the second preset values, such as a null value or a negative number, and after the control parameter is successfully matched, the value of the flag bit information may be set to one of the first preset values, such as a positive number of 1, 2, or 0. The expression form of the flag bit information is not limited, and the flag bit information may also be set to letters or other symbols, for example, when the control parameter is not stored, the flag bit information is set to a, and when the control parameter is stored, the flag bit information is set to B, C and other letters; alternatively, when the control parameter is not stored, the flag bit information is set to 0x01, and when the control parameter is stored, the flag bit information is set to a numerical value such as 0x02 or 0x 03. The image forming device stores the control parameter successfully matched for the first time as a first control parameter, and modifies the zone bit information into a first preset value corresponding to the first control parameter. After the image forming apparatus is restarted, the flag bit information is detected to be the first preset value, and it can be determined that the first control parameter has been successfully matched and stored before the image forming apparatus is started this time. The image forming device directly obtains a prestored first control parameter and controls the laser scanning unit to operate based on the first control parameter. In one embodiment, the flag information may be set to 1 if the current LSU is of a pentaprism type, and may be set to 2 if the current LSU is of a tetraprism type.
And 102, in the operation process of the laser scanning unit, determining whether the first control parameter is matched with the laser scanning unit according to the line synchronization signal parameter of the laser scanning unit.
The horizontal synchronization signal parameter of the embodiment of the present invention may include at least one of the number and the period of the horizontal synchronization signal. As shown in fig. 2, the laser scanning unit specifically includes: a light emission control circuit 201, a laser diode 202, a focusing lens 203, a polygon motor 204, a condensing lens 205, a reflecting mirror 206, a reflecting mirror 207, a focusing lens 208, a focusing lens 209, and a line synchronization sensor 210. The light-emitting control circuit 201 can control the laser diode 202 to emit light beams, the light beams are converted into parallel light through the focusing lens 203 and reach the polygon motor 204, the polygon motor 205 reflects the light beams, and the light beams irradiate towards two aspects after passing through the focusing lens 205, wherein the reflecting mirror 206 reflects the light beams to the focusing lens 209, and the focusing lens 209 focuses the parallel light to the line synchronization sensor 210; the focusing lens 208 focuses the light beam and reflects the light beam onto the surface of the photosensitive drum for scanning by the mirror 207. After the laser scanning unit is operated, the polygon motor rotates to change the angle of the reflected light beam, and each time the polygon motor rotates one side, one line can be scanned on the photosensitive drum, and the time for scanning one line is the period of the line synchronization signal. The reflected light from the polygon motor 205 reaches the line synchronization sensor 210 in addition to the photosensitive drum, the line synchronization sensor 210 may determine an actual line synchronization signal period of the laser scanning unit, a preset line synchronization signal period is recorded in the first control parameter, and the image forming apparatus may compare the actual line synchronization signal period with the preset line synchronization signal period to determine whether the first control parameter matches the laser scanning unit. Specifically, if the difference between the actual line synchronizing signal period and the preset line synchronizing signal period does not exceed the first threshold, it may be determined that the first control parameter matches the laser scanning unit, otherwise, it may be determined that the first control parameter does not match the laser scanning unit.
And 103, if the laser scanning unit is not matched with the laser scanning unit, re-executing the control parameter matching process, determining a second control parameter matched with the laser scanning unit, and controlling the laser scanning unit to operate based on the second control parameter.
If the type of the laser scanning unit is replaced before the image forming apparatus is started up, the previously stored first control parameter may not match the current laser scanning unit, and thus the control parameter matching procedure needs to be re-executed. The control parameters mainly include: the type of the light-emitting diode, the resolution ratio, the printing amplitude, the effective scanning angle, the number of the polygon mirror surfaces, the line synchronization signal period, the line scanning frequency, the time of one rotation of the polygon motor, the rotating speed of the polygon motor, the included angle between the polygon mirrors, the effective scanning utilization rate and the like. The number of polygon mirror surfaces, the period of the line synchronization signal, and the rotational speed of the polygon mirror motor are main influencing factors, the number of polygon mirror surfaces of different types of laser scanning units may be different, and when the rotational speeds of the polygon mirror motors are the same, the period of the line synchronization signal is inversely proportional to the number of polygon mirror surfaces. The correlation formula includes: polygon motor speed = line synchronization signal period 60/polygon mirror number. The image forming apparatus may acquire a plurality of control parameters configured in advance, each control parameter including different polygon motor rotation speeds and a corresponding line synchronization signal period T1, then control a motor operation of the laser scanning unit based on the polygon motor rotation speed of any control parameter, and determine an actual line synchronization signal period T2 of the current laser scanning unit, if a difference between T1 and T2 does not exceed a first threshold, determine the current control parameter as a second control parameter matched with the laser scanning unit, and if a difference between T1 and T2 exceeds the first threshold, switch other control parameters for matching. After the matching is successful, the image forming apparatus deletes the previously stored first control parameter and stores the successfully matched control parameter as the second control parameter, while modifying the flag information, for example, modifying the flag information from 1 to 2.
In one embodiment, in step 101, if it is detected that the flag bit information is a negative number (LSU is first installed) or other second preset value after the image forming apparatus is started, the control parameter matching process is directly executed, and after the matching is successful, the matched parameter is stored as a second control parameter, and the flag bit information is modified to be a positive number or other first preset value.
In the existing technical solution, a special memory chip is usually configured to store all the control parameters and flag bit information that are successfully matched before in an associated manner, for example, the flag bit 1-a type control parameter, the flag bit 2-B type control parameter, the flag bit 3-C type control parameter, and the like, and after each start of the image forming apparatus, the LSU identification is performed to obtain the corresponding control parameter. In the embodiment of the invention, the image forming device only stores the control parameters and the zone bit information which are successfully matched currently, for example, the zone bit 1-A control parameters are stored after the A-type control parameters are successfully matched, and the zone bit 1-A control parameters are deleted and the zone bit 2-B control parameters are stored before the B-type control parameters are successfully matched. Therefore, a special chip is not required to store the associated information, and the space is saved.
In the embodiment of the invention, after the image forming device is started, the laser scanning unit is directly controlled to operate based on the stored first control parameter, so that the waiting time caused by parameter matching is reduced; and secondly, if the first control parameter is found not to be matched, the control parameter matching process is executed again, and the first control parameter is deleted after the matching is successful.
Fig. 3 is a flowchart of another control parameter matching method according to an embodiment of the present invention. As shown in fig. 3, the method may include:
After the image forming apparatus is started, the flag bit information is determined, if the flag bit information is detected to be a second preset value (if the flag bit information is a positive number), it is determined that the matching is successful and the control parameter has been stored, step 307 is performed, if the flag bit information is a first preset value (if the flag bit information is a negative number), it is determined that the control parameter has not been stored, and step 302 is performed.
And if the control parameters are not stored, matching the control parameters in sequence, and selecting one control parameter to operate the LSU.
And step 304, judging whether the actual line synchronization signal period is matched with the preset line synchronization signal period recorded by the current control parameter.
The control parameter currently in the matching process records a 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, the control parameter can be determined to be matched with the LSU. Specifically, an error threshold may be set in advance, and if the difference between the actual line synchronizing signal period and the preset line synchronizing signal period does not exceed the error threshold, it is determined that the current control parameter matches the LSU.
And step 305, switching the control parameters of the B (C, D, E) class for matching.
And if the current control parameter fails to be matched, switching other control parameters for matching.
If the matching is successful, the image forming apparatus stores the current control parameter, and sets the flag bit information to a positive number, and if the matching is failed, sets the flag bit information to a negative number.
In a specific embodiment, the image forming apparatus sets different flag bit information according to the reason of the matching failure and reports the reason, if the error is large, the flag bit information is set to-2, and the cycle of the line synchronization signal is reported to be abnormal; if all the control parameters are not matched, setting flag bit information as-1, and reporting LSU identification failure; and if the motor parameter is abnormal, the motor is started unstably, setting the flag bit information to be-3, reporting the motor abnormality, and matching after the user can replace the motor.
During the operation of the LSU, the image forming apparatus still performs detection of the period of the synchronization signal, and if the period of the line synchronization signal is found to be abnormal, performs the matching process of the control parameters again.
In the actual matching process, the image forming device can judge whether to match according to whether the LSU rotates, the rotation represents that the LSU is being matched, the LSU rotates and then is normally ready to represent that the LSU is successfully matched, if the LSU is damaged and does not rotate, the line synchronization signal period is not matched, the image forming device can report errors, and the errors can be reported for 2 times under the common condition.
In one embodiment, to avoid the control parameter matching process 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 minimum rotating speed of the motor can be selected for matching, and if the matching fails, other control parameters are switched according to the sequence of the rotating speed of the motor from small to large.
In the embodiment of the invention, if the stored control parameters are determined after the image forming device is started, the control parameters are directly acquired to control the LSU to operate, whether the control parameters are matched or not is judged according to the line synchronization signal period in the operation process, and the waiting time can be reduced because the type identification (control parameter matching) of the LSU is carried out without setting the rotating speed of the motor. And if the control parameters are determined not to be stored, the LSU is operated based on different control parameters, matching is carried out according to the actual line synchronization signal period, and the line synchronization sensor is arranged in the LSU, so that the actual line synchronization signal period can be determined.
Fig. 4 is a schematic structural diagram of a control parameter matching apparatus according to an embodiment of the present invention. The apparatus may be used as a specific device to implement the control parameter matching method provided in the embodiment of the present invention, and as shown in fig. 4, the apparatus may include: a processing module 410, a determining module 420 and a matching module 430.
