Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printers, in particular to a method and device for adjusting a print head, an electronic device and a storage medium. BACKGROUND

[0002] With the development of printers, the improvement of the living standards of residents and the office level of enterprises, the application of printers is becoming more and more common, and has been completely integrated into people's daily life. Therefore, the performance of the printer is one of the key issues that people are concerned about.

[0003] The performance of the printer is closely related to the performance, stability and synergy of each component in the printer, such as the synergy function of the print head and the installation information of the print head. If there is a fault in each component in the printer or the synergy of each component is limited, the printing effect of the printer will be greatly reduced, and the user's experience will be affected. At present, the printers with high printing efficiency on the market generally have two or more print heads, and use multiple print heads to work together to improve the printing speed of the printer. However, there is a parallel error and offset between the print heads of the multi-print head printing device, which will cause the printing content of the printer to be misaligned and affect the printing effect.

[0004] At present, the calibration method of the print head is to manually adjust the position of the print head by the technician according to experience, but the adjustment ability of the technician is limited, and it is very difficult to manually adjust the position of the print head. Once the offset / parallel error of the print head to be adjusted is small, the technician will not be able to accurately adjust the position of the print head, and improper position adjustment will affect the printing quality of the printer.

[0038] In order to make the technical solutions in the embodiments of the present application clearer, the accompanying drawings needed in the embodiments will be briefly introduced. Obviously, the accompanying drawings in the following description only need to be some embodiments of the present application, and other drawings can be obtained by those skilled in the art without any creative effort.

[0039] It is to be understood that the terms "first", "second", and the like, used in the description and the claims of the application and the above drawings, are used to distinguish between similar objects, and are not necessarily used to describe a particular sequential or chronological order. It is to be understood that the use of data herein is not to be construed as limiting, but rather, the embodiments of the application described herein are capable of being practiced in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprise" and "include", and variations thereof, are intended to cover non-exclusive inclusions, such that processes, methods, systems, products, or devices that comprise, include, or are otherwise including a list of steps or elements, can include those not expressly listed or inherent to such processes, methods, systems, products, or devices.

[0040] Embodiment one

[0041] Figure 1 is a flowchart of a method for adjusting a print head sheet according to an embodiment of the application. The embodiment can be applicable to horizontal calibration of the print head sheet, left-right alignment calibration of the print head sheet, etc. The method can be executed by an adjusting device for the print head sheet according to the application. The device can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated in an electronic device. The following embodiment will be described by taking the device integrated in the electronic device as an example. Referring to Figure 1 , the method specifically includes the following steps:

[0042] S101, determining an initial working mode of the print head sheet based on an adjustment requirement of the print head sheet.

[0043] The initial print head sheet includes at least two print head sheets. The number of print head sheets is related to the model of the printer, and is generally 2 to 4. Different print head sheets can print different color contents. After installation, the print head sheet can have parallel errors and alignment errors. The parallel errors can cause the printed contents of the print head sheets to be inclined. The alignment errors can cause the starting printing positions of the print head sheets to be different. Both types of errors can affect the printing effect.

[0044] Specifically, the adjustment requirement includes a parallel adjustment requirement and an alignment adjustment requirement. The parallel adjustment requirement can be understood as a starting instruction for adjusting the parallel errors of the print head sheets. The alignment adjustment requirement can be understood as a starting instruction for adjusting the alignment errors of the print head sheets. The working mode includes a first working mode and a second working mode. The first working mode corresponds to the parallel adjustment requirement, and the second working mode corresponds to the alignment adjustment requirement. Further, the first working mode is based on a first preset direction and a first preset distance, and the second working mode is based on a second preset direction and a second preset distance.

[0045] For example, when the adjustment requirement of the print head piece is a parallel adjustment requirement, the working mode of the initial print head piece is determined to be running based on the first preset direction and the first preset distance, and when the adjustment requirement of the print head piece is an alignment adjustment requirement, the working mode of the initial print head piece is determined to be running based on the second preset direction and the second preset distance.

[0046] In this way, the movement mode of the print head piece can be determined according to different adjustment requirements, and the adjustment efficiency and accuracy of the print head piece are improved.

[0047] Optionally, the adjustment requirement of the print head piece in the embodiment includes a parallel adjustment requirement and an alignment adjustment requirement. Therefore, the working mode of the initial print head piece is determined based on the adjustment requirement, including: determining whether the adjustment requirement is a parallel adjustment requirement; if the adjustment requirement is a parallel adjustment requirement, determining the working mode of the initial print head piece to be running based on the first preset direction and the first preset distance; if the adjustment requirement is not a parallel adjustment requirement, determining the adjustment requirement to be an alignment adjustment requirement, and considering that the working mode of the initial print head piece is running based on the second preset direction and the second preset distance; or, the working mode of the initial print head piece is determined based on the adjustment requirement, including: determining whether the adjustment requirement is an alignment adjustment requirement; if the adjustment requirement is an alignment adjustment requirement, determining the working mode of the initial print head piece to be running based on the second preset direction and the second preset distance; if the adjustment requirement is not an alignment adjustment requirement, determining the adjustment requirement to be a parallel adjustment requirement, and considering that the working mode of the initial print head piece is running based on the first preset direction and the first preset distance. In this way, the working mode of the print head piece can be quickly determined.

[0048] The first preset distance and the second preset distance are used to observe the running information of the print head piece, and the specific values are not limited, and can be set and adjusted according to the size of the print paper, the running logic of the print head piece, the paper feeding speed of the printer, and the like. The embodiment does not limit this.

[0049] Specifically, the control of the print head piece to operate based on the first preset direction and the first preset distance can be understood as the control of the print head piece to print a straight line with a length of the first preset distance, that is, the determination of the printing points of the print head piece that need to perform the printing work based on the first preset distance, and the control of the printing points of the print head piece to perform the printing work at the same time, so as to print a straight line with a length of the first preset distance. The control of the print head piece to operate based on the second preset direction and the second preset distance can be understood as the control of the print head piece to print an inclined line with a length of the second preset distance, that is, the determination of the number of the printing points of the print head piece that need to perform the printing work based on the second preset distance, and the control of the printing points of the print head piece to perform the printing work in turn in the paper feeding process, so as to print an inclined line with a length of the second preset distance. The specific inclination angle is related to the calibration logic of the printer and the paper feeding speed, which is not limited in the embodiment.

[0050] S102, control the initial print head piece to operate based on the working mode, and obtain the operation information of the initial print head piece.

[0051] The operation information of the initial print head piece can be understood as distance information between the initial print head pieces, which is used to determine whether there is a parallel error and / or an alignment error in the initial print head pieces.

[0052] Specifically, the control of the initial print head piece to operate based on the working mode can be understood as the control of the initial print head piece to operate based on the working mode determined in step S101. The obtaining of the operation information of the initial print head piece can be understood as the determination of at least one relative distance between the print head pieces. The relative distance is essentially the distance between the lines printed by the print head pieces. The number of the relative distances corresponds to the adjustment requirement. For example, at least two relative distances are required for the parallel adjustment of the print head pieces, and at least one relative distance is required for the alignment adjustment of the print head pieces.

[0053] For example, the obtaining of the operation information of the initial print head piece includes the determination of the printing tracks of the print head pieces, and the determination of the relative distances between the print head pieces according to the printing tracks.

[0054] The advantage of such a setting is that the operation information can be determined according to the adjustment requirement of the print head piece, thereby saving resources.

[0055] S103, determining a target print head piece and an adjustment mode of the target print head piece based on the operation information.

[0056] The target print head piece can be understood as a print head piece that needs to be adjusted and calibrated. The adjustment mode of the target print head piece can be understood as the calibration information of the target print head piece, including the adjustment angle, the adjustment distance, etc. The embodiment is not limited in this regard.

[0057] Specifically, the target print head piece is at least one print head piece in the initial print head pieces.

[0058] For example, assuming that the printer has two print head pieces, if it is determined according to the running information that the print head piece that needs to be calibrated is print head piece 1, and the calibration information is to move Y distance in the X direction, then the target print head piece is print head piece 1, and the adjustment mode of the target print head piece is to move Y distance in the X direction.

[0059] S104, adjusting the target print head piece based on the adjustment mode.

[0060] Specifically, adjusting the target print head piece based on the adjustment mode can be understood as adjusting the position of the target print head piece based on the adjustment mode of the target print head piece determined in step S103, so as to improve the printing quality of the printer.

[0061] For example, assuming that the target print head piece is print head piece 1, and the adjustment mode of the target print head piece is to move Y distance in the X direction, then adjusting the target print head piece based on the adjustment mode is to move print head piece 1 Y distance in the X direction.

[0062] The advantage of such a setting is that the print head piece can be adjusted according to the adjustment requirements of the print head piece and the running information of the print head piece, improving the adjustment accuracy of the print head piece and enhancing the printing effect of the printer.

[0063] The technical scheme of the embodiment determines the working mode of the initial print head piece based on the adjustment requirements of the print head piece, wherein the initial print head piece includes at least two print head pieces; controls the initial print head piece to run based on the working mode, and obtains the running information of the initial print head piece; determines the target print head piece and the adjustment mode of the target print head piece based on the running information, wherein the target print head piece is at least one print head piece in the initial print head pieces; and adjusts the target print head piece based on the adjustment mode. The working mode of the print head piece can be determined according to the adjustment requirements of the print head piece, and the adjustment mode of the print head piece can be determined according to the running information of the print head piece, which can improve the adjustment accuracy of the print head piece and enhance the printing effect of the printer. The problems of manually adjusting the position of the print head piece by the technician according to experience, the limited adjustment ability of the technician, the difficulty of manually adjusting the position of the print head piece, and the inability of the technician to accurately adjust the position of the print head piece when the offset and / or parallel error of the print head piece to be adjusted is small, thereby reducing the printing quality of the printer, are solved.

[0064] Embodiment two

[0065] Figure 2is a flowchart of a method for adjusting a print head piece according to Embodiment Two of the present application. The present embodiment is applicable to parallel calibration of a print head piece. The method can be performed by an adjusting device for a print head piece provided by the present application. The device can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated in an electronic device. The following embodiments will be described by taking the device integrated in an electronic device as an example. Refer to Figure 2 The method specifically includes the following steps.

[0066] S201: Determine an initial working mode of the print head piece based on an adjustment requirement of the print head piece.

[0067] In the present embodiment, determining the initial working mode of the print head piece based on the adjustment requirement of the print head piece can be understood as determining the initial working mode of the print head piece based on the parallel adjustment requirement as running based on a first preset direction and a first preset distance.

[0068] The first direction represents a horizontal direction on the paper, for example, row information of the paper or column information of the paper. The specific orientation of the horizontal direction is related to the calibration logic of the printer, which is not limited in the present embodiment.

[0069] The purpose of controlling the initial print head piece to run based on the first preset direction and the first preset distance is to control each print head piece to print a preset length of horizontal line, so as to determine whether there is a parallel error between the print head pieces according to the relative distance between the print head pieces.

[0070] S202: Determine at least two running information collection positions.

[0071] The running information collection position can be understood as a position for determining the relative distance between the print head pieces. Specifically, the relative distance between the print head pieces at at least two different positions can be used to determine whether there is a parallel error between the print head pieces. For example, if the relative distances at multiple positions are equal or within a certain range, it is considered that the print head pieces are in a relatively parallel state, and there is no parallel error between the print head pieces. If the relative distances at multiple positions are quite different, it is considered that the print head pieces have an inclination problem, and there is a parallel error between the print head pieces.

[0072] The advantage of such setting is to effectively improve the accuracy of the running data of the print head piece.

[0073] S203: Control the initial print head piece to run based on the first preset direction and the first preset distance, and determine a time difference set between the print tracks of the initial print head piece based on an information collector at the running information collection position.

[0074] The information collector can be understood as a device for collecting printing track information, for example, a photoelectric pair. Specifically, after the print head piece is operated, a printing track is left on the paper. The reflected / transmitted signal of the photoelectric pair when passing through the printing track is different from the signal when passing through the white paper. The time difference set can be determined by the time of the photoelectric pair passing through the printing track of each print head piece. The time difference set includes at least two sub-time differences. The sub-time differences correspond to the operation information collection positions one by one.

[0075] For example, assuming that the operation information collection positions are position 1 and position 2, the print head pieces include print head piece 1 and print head piece 2, and the print head pieces leave a black printing track on the printing paper when they are operated. If the photoelectric pair detects the printing track of print head piece 1 at time 1 and the printing track of print head piece 2 at time 2 at position 1, and detects the printing track of print head piece 1 at time 3 and the printing track of print head piece 2 at time 4 at position 2, then the time difference set includes two sub-time differences. One sub-time difference is the difference between time 2 and time 1, and the other sub-time difference is the difference between time 4 and time 3.

[0076] S204, determining at least two first target distances according to the paper feed speed of the printer and the time difference set.

[0077] The first target distance is the relative distance between the initial print head pieces at the operation information collection position. Specifically, the first target distance can be determined according to the product of the paper feed speed of the printer and the sub-time difference.

[0078] For example, assuming that the operation information collection positions are position 1 and position 2, and the print head pieces include print head piece 1 and print head piece 2, then the first target distance includes distance 1 and distance 2. Distance 1 is the distance between the printing track of print head piece 1 and the printing track of print head piece 2 at position 1 (which can be understood as a straight line printed by print head piece 1). Figure 3 is a schematic diagram of a print head piece provided by the second embodiment of the present application. In the diagram, d1 represents distance 1, and d2 represents distance 2. According to the relative relationship between d1 and d2, it can be determined whether print head piece 1 and print head piece 2 have parallel error. For example, if d2 is greater than d1, then print head piece 1 has deviation away from print head piece 2 or print head piece 2 has deviation away from print head piece 1. If d2 is less than d1, then print head piece 1 has deviation close to print head piece 2 or print head piece 2 has deviation close to print head piece 1.

[0079] S205, determining the target print head piece according to the selection rule of the initial print head piece and the target print head piece.

[0080] The selection rule of the target print head piece can be understood as indicative information of selecting the target print head piece, for example, selecting a print head piece with relatively parallel print tracks as the target print head piece, selecting a print head piece with relatively non-parallel print tracks as the target print head piece, selecting all print head pieces as the target print head piece, etc. The selection rule of the target print head piece can be set according to adjustment requirements, which is not limited in the embodiment.

[0081] For example, Figure 3 As described above, the print head piece 1 can be selected as the target print head piece. When adjusting, only the position of the print head piece 1 needs to be adjusted according to the two relative distances. The advantage of this setting is that it can simplify the adjustment mode of the print head piece and improve the adjustment efficiency of the print head piece while ensuring the adjustment effect.

[0082] S206, determining whether the distance difference of the at least two first target distances is less than or equal to a preset distance difference.

[0083] The preset distance difference can be understood as a standard for measuring whether the first target distances are equal. The specific value of the preset distance difference is related to the accuracy of the print head piece. If the difference between the first target distances is less than or equal to the preset distance difference, it is considered that the first target distances are equal.

[0084] Specifically, if the distance difference is less than or equal to the preset distance difference, step S207 is performed, and if the distance difference is greater than the preset distance difference, step S208 is performed.

[0085] S207, determining that the adjustment mode is not adjusted.

[0086] Specifically, when the distance difference is less than or equal to the preset distance difference, it is considered that the print head pieces are in a relatively parallel state, and there is no parallel error between the print head pieces, so no adjustment is needed.

[0087] The advantage of this setting is that it can save adjustment resources.

[0088] S208, determining a first intermediate target distance based on the at least two first target distances, and determining that the adjustment mode is to adjust the target print head piece based on a first adjustment direction and a first adjustment distance.

[0089] The first intermediate target distance is the distance with the highest distance value among all target distances, the first adjustment direction is the direction in which the target print head piece approaches other print head pieces, the first adjustment distance is half of the distance difference between the first intermediate target distance and a second intermediate target distance, and the second intermediate target distance is a target distance other than the first intermediate target distance among the at least two target distances.

[0090] For example, Figure 3For example, the determination process of the adjustment mode is described. It is assumed that the starting printing point of the printhead sheet is located at the left end of the printing track (the position where the paper starts to be written), and the ending printing point of the printhead sheet is located at the right end of the printing track (the position where the paper ends to be written). If d1>d2, the first intermediate target distance is d1, the second intermediate target distance is d2, the first adjustment direction is the direction of approaching printhead sheet 2, the first adjustment distance is (d1-d2) / 2, and the adjustment mode is to adjust printhead sheet 1 to approach printhead sheet 2 by (d1-d2) / 2 (specifically, the left / starting end of printhead sheet 1 is adjusted to approach printhead sheet 2). If d2>d1, the first intermediate target distance is d2, the second intermediate target distance is d1, the first adjustment direction is the direction of approaching printhead sheet 2, the first adjustment distance is (d2-d1) / 2, and the adjustment mode is to adjust printhead sheet 1 to approach printhead sheet 2 by (d2-d1) / 2 (specifically, the right / ending end of printhead sheet 1 is adjusted to approach printhead sheet 2).

[0091] Further, d1 and d2 can also be compared with the ideal distance, and the target printhead adjustment mode is determined according to the difference between the ideal distance and d1 and d2.

[0092] S209, adjusting the target printhead based on the adjustment mode.

[0093] Specifically, adjusting the target printhead based on the adjustment mode can be understood as adjusting the target printhead based on the above-determined adjustment mode.

[0095] Embodiment three

[0096] Figure 4 is a flowchart of a print head piece adjustment method provided by the embodiment three of the present application. The embodiment can be applicable to left-right alignment calibration of the print head piece. The method can be executed by a print head piece adjustment device provided by the present application. The device can be realized in the form of software and / or hardware. In a specific embodiment, the device can be integrated in an electronic device. The following embodiment will be described by taking the device integrated in the electronic device as an example. Refer to Figure 4 , the method specifically includes the following steps:

[0097] S401, determine the working mode of the initial print head piece based on the adjustment requirement of the print head piece.

[0098] In this embodiment, the initial print head piece is determined based on the adjustment requirements of the print head piece. The working mode of the initial print head piece can be understood as being determined based on the alignment adjustment requirements. The working mode of the initial print head piece is based on the second preset direction and the second preset distance. Specifically, the number of print points of the print head piece that need to perform the printing work is determined based on the second preset distance. The print points of each print head piece are controlled to perform the printing work in sequence during the paper feeding process, so as to print an inclined line with a length of the second preset distance.

[0099] In the formula, the second direction represents the inclination angle of the printing track. The specific size of the inclination angle is related to the paper feeding speed of the printer, the relative distance of each print point in the print head piece, and other factors. The present embodiment is not limited here.

[0100] The purpose of controlling the initial print head piece to run based on the second preset direction and the second preset distance is to control each print head piece to print an inclined line with a preset length, so as to determine whether there is an alignment error between the print head pieces according to the relative distance between the print head pieces.

[0101] S402, determine the collection position of the running information.

[0102] Specifically, the running information collection position can be understood as a position for determining the relative distance between the print head pieces. It is worth noting that only one relative position needs to be collected in the present embodiment. According to the difference between the collected relative position and the ideal position, whether there is an alignment error between the print head pieces can be determined.

[0103] The advantage of such a setting is to save information collection resources and the working task of the information collector.

[0104] S403, control the initial print head piece to run based on the second preset direction and the second preset distance, and determine the time difference between the printing tracks of the initial print head piece based on the information collector at the collection position.

[0105] In the formula, the information collector can be understood as a device for collecting printing track information, such as a photoelectric pair. Specifically, after each print head piece runs, it will leave an inclined black printing track on the paper. The reflected / transmitted signal of the photoelectric pair when passing through the printing track is different from the signal when passing through the white paper. The time difference between the printing tracks of the print head pieces can be determined by the time when the photoelectric pair passes through the printing track of each print head piece.

[0106] For example, it is assumed that the running information collection position is position 3, the print head pieces include print head piece 1 and print head piece 2, and the print head pieces will leave an inclined black printing track on the printing paper when running. If the photoelectric pair detects the printing track of print head piece 1 at time 5 and detects the printing track of print head piece 2 at time 6, then the time difference is the difference between time 6 and time 5.

[0107] S404, determining a second target distance of the initial print head piece according to the paper feed speed of the printer and the time difference.

[0108] The second target distance is the relative distance between the print head pieces at the information collection position. Specifically, the second target distance can be determined according to the product of the paper feed speed of the printer and the time difference.

[0109] For example, assuming that the time difference is T and the paper feed speed of the printer is V, the second target distance is T*V.

[0110] Specifically, when the second target distance is equal to the ideal distance or the error between the two is within a certain range, it is considered that there is no alignment error between the print head pieces, and when the error between the second target distance and the ideal distance is too large, it is considered that there is an alignment error between the print head pieces.

[0111] For example, assuming that the running information collection position is position 4 and the print head pieces include print head piece 1 and print head piece 2, the second target distance includes distance 4, which is the distance between the print track of print head piece 1 (which can be understood as the inclined straight line printed by print head piece 1) and the print track of print head piece 2 at position 1. Figure 5 is a schematic diagram of a print head piece provided by the third embodiment of the present application, in which the inclined straight line represents the actual print track of the print head piece, the inclined dashed line represents the ideal print track of print head piece 1, d3 represents the ideal distance, and d4 represents the actual distance between print head piece 1 and print head piece 2. According to the relative relationship between d3 and d4, it can be determined whether print head piece 1 and print head piece 2 have an alignment error, for example, if d4 is greater than d3, print head piece 1 has a deviation of lagging behind print head piece 2 or print head piece 2 has a deviation of advancing ahead of print head piece 1, if d4 is less than d3, print head piece 1 has a deviation of advancing ahead of print head piece 2 or print head piece 2 has a deviation of lagging behind print head piece 1.

[0112] S405, determining a reference print head piece according to a selection rule of the initial print head piece and the reference print head piece.

[0113] The reference print head piece can be understood as a medium for determining the relative relationship between the print head pieces, and the selection rule of the reference print head piece can be understood as indicative information for selecting the reference print head piece, for example, selecting a print head piece whose print track is closer to the header position as the reference print head piece, selecting a print head piece whose print track is closer to the footer position as the reference print head piece, etc. The selection rule of the reference print head piece can be set according to the adjustment requirements, which is not limited in the present embodiment.

[0114] For example, as shown in FIG. 4, the selection rule of the reference print head piece is that the print head piece whose print track is closer to the header position is selected as the reference print head piece. Figure 5The embodiment can select the print head piece 1 as the reference print head piece, and adjust the position relationship between the print head piece 1 and the print head piece 2 according to the inclination angle of the print track, the ideal distance and the actual distance of the print track.

[0115] The print head piece to be adjusted can be conveniently selected.

[0116] S406, determining the offset of the target print head piece and the reference print head piece based on the third preset distance, the inclination angle of the reference print head piece and the second target distance.

[0117] The third preset distance can be understood as the ideal distance between the print head pieces. The inclination angle of the reference print head piece is related to the paper feeding speed, the parameters of the print head piece and the control logic, and can be understood as a known quantity in the embodiment. The target print head piece can be understood as the print head piece to be adjusted, and the offset can be understood as the left-right offset degree between the print head pieces.

[0118] For example, as shown in FIG. 4, θ represents the inclination angle of the reference print head piece, d3 represents the third preset distance, d4 represents the second target distance, and d5 represents the offset. Figure 5 As shown in FIG. 4, tanθ=(d4-d3) / d5, so d5=(d4-d3) / tanθ.

[0119] It is worth noting that the d5 can be with direction or without direction. The d5 with direction can represent the offset degree and the offset direction, and the offset direction can be used to represent the leading / lagging relationship between the print head piece 1 and the print head piece 2.

[0120] Specifically, when the print head piece 1 lags behind the print head piece 2, the print head piece 2 is considered to be the print head piece to be adjusted, that is, the target print head piece is the print head piece 2. When the print head piece 1 leads the print head piece 2, the print head piece 1 is considered to be the print head piece to be adjusted, that is, the target print head piece is the print head piece 1. Figure 5 In the embodiment, the print head piece 1 lags behind the print head piece 2, and the print head piece 2 is the print head piece to be adjusted, that is, the target print head piece is the print head piece 2.

[0121] S407, determining whether the difference between the offset and the third preset distance is less than or equal to a preset offset.

[0122] The preset offset can be understood as a basis for measuring the distance difference between the second target distance and the ideal distance. The specific value of the preset offset is related to the precision of the print head piece. If the distance difference between the second target distance and the ideal distance is less than or equal to the preset offset, it is considered that the difference between the second target distance and the ideal distance is small. If the distance difference between the second target distance and the ideal distance is greater than the preset offset, it is considered that the difference between the second target distance and the ideal distance is large.

[0123] Specifically, if the offset is less than or equal to the preset offset, step S408 is performed, and if the offset is greater than the preset offset, step S409 is performed.

[0124] The advantage of such a setting is that the calibration method of the print head piece can be determined according to the actual data of the second target distance and the ideal distance.

[0125] S408, determining that the adjustment method is to update the starting printing point of the target print head piece based on the offset.

[0126] The updating of the starting printing point of the target print head piece can be understood as resetting the starting printing point of the print head piece. Specifically, Figure 6 is another schematic diagram of a print head piece provided in Embodiment Three of the present application, Figure 6 The thick black dots in the diagram represent the printing points of the print head piece. As can be seen from the diagram, the print head piece 1 lags behind the print head piece 2, so it is necessary to redefine the starting printing point of the print head piece 2 in order to align the two print head pieces. P1 in the diagram is the starting printing point of the updated print head piece 2, and the printing points before the P1 point will not be processed for any printing task.

[0127] The advantage of such a setting is that the print head pieces are aligned, reducing the misplacement of the printed content and improving the printing quality.

[0128] S409, determining that the adjustment method is to adjust the position information of the starting printing point of the target print head piece based on the offset.

[0129] Specifically, adjusting the position information of the starting printing point of the target print head piece based on the offset can be understood as moving the print head piece by a distance corresponding to the offset, so as to align the print head pieces.

[0130] A large degree of offset is not suitable for redefining the starting point of the print head piece, and too many print head pieces stopping working will affect the printing speed, printing quality and printing efficiency. The advantage of such a setting is that when the offset degree is large, the target print head piece is directly moved based on the offset, which can quickly and efficiently align the print head pieces.

[0131] S410, adjusting the target print head piece based on the adjustment method.

[0132] Specifically, adjusting the target print head piece based on the adjustment mode can be understood as adjusting the target print head piece based on the determined adjustment mode. If the adjustment mode is to update the starting print point of the target print head piece, the starting print point of the target print head piece is reset. If the adjustment mode is to adjust the position information of the starting print point of the target print head piece, the target print head piece is moved to adjust the position of the initial print point of the target print head piece.

[0133] The technical scheme of the embodiment determines the working mode of the initial print head piece based on the adjustment requirement of the print head piece, determines the collection position of the running information, controls the initial print head piece to run based on the second preset direction and the second preset distance, determines the time difference between the print tracks of the initial print head piece based on the information collector at the collection position, determines the second target distance of the initial print head piece according to the paper feed speed of the printer and the time difference, determines the reference print head piece according to the selection rule of the initial print head piece and the reference print head piece, determines the offset amount of the target print head piece and the reference print head piece based on the third preset distance, the inclination angle of the reference print head piece and the second target distance, determines whether the difference between the offset amount and the third preset distance is less than or equal to the preset offset amount, determines the adjustment mode as updating the starting print point of the target print head piece based on the offset amount if the offset amount is less than or equal to the preset offset amount, determines the adjustment mode as adjusting the position information of the starting print point of the target print head piece based on the offset amount if the offset amount is greater than the preset offset amount, and adjusts the target print head piece based on the adjustment mode. The working mode of the print head piece can be determined according to the alignment adjustment requirement of the print head piece, the time difference information between the print head pieces is collected at the information collection position, and the adjustment mode of the target print head piece is determined according to the relative distance between the print head pieces, the ideal distance and the inclination angle of the print track, which can improve the adjustment accuracy of the print head piece and enhance the printing effect of the printer. The problems of manually adjusting the position of the print head piece by the technician according to experience, the limited adjustment ability of the technician, the difficulty of manually adjusting the position of the print head piece, the inability of the technician to accurately adjust the position of the print head piece when the offset and / or parallel error of the print head piece to be adjusted is small, and the reduction of the printing quality of the printer are solved.
