Description

Technical Field

[0001] The present application relates to the field of image forming technology, and in particular to a fixing control method, an image forming device, an electronic device and a storage medium. Background Art

[0002] An image forming device is a device that forms an image on an imaging medium through the imaging principle, and generally includes a fixing component inside, wherein the fixing component is used to heat and fix the toner pattern corresponding to the image forming task onto the imaging medium.

[0003] Under the action of high temperature and high pressure, the material life of the fixing component will be affected. It is understandable that as the number of printing and fixing times of the fixing component in the image forming device increases, the fixing component will be worn to a certain extent.

[0004] Furthermore, during the process from when the image forming apparatus receives an image forming job task to when it completes printing the first page of the image forming job task, the fixing component is in an idle state most of the time, which results in a loss of the life of the fixing component.

[0005] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Summary of the invention

[0006] In view of this, the present application provides a fixing control method, an image forming device, an electronic device and a storage medium, so as to solve the problem in the prior art that in the process from when the image forming device receives an image forming job task to when the first page of the image forming job task is printed, the fixing component is in an idling state most of the time, thereby causing the life of the fixing component to be lost.

[0007] In a first aspect, an embodiment of the present application provides a fixing control method, which is applied to an image forming device, wherein the image forming device includes a fixing component, and the fixing component includes a pressure roller and a heating roller. The method includes:

[0008] In response to the issued image forming job task, controlling the rotation speed of the pressure roller and the heating roller in the fixing component to be a first rotation speed;

[0009] When the position of the imaging medium corresponding to the image forming task satisfies a preset condition, the rotational speed of the pressure roller and the heating roller in the fixing component is controlled to be a second rotational speed, wherein the preset condition is used to characterize that the imaging medium is about to enter the fixing component; the second rotational speed is the rotational speed of the pressure roller and the heating roller under normal working conditions of the fixing component; and the first rotational speed is less than the second rotational speed.

[0010] In an embodiment of the present application, in response to an issued image forming job task, first control the rotation speeds of the pressure roller and the heating roller in the fixing unit to a first rotation speed; when the position of the imaging medium corresponding to the image forming job task meets a preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to a second rotation speed. It can be understood that after the image forming job task is issued, the fixing unit will control the pressure roller and the heating roller to maintain a relatively low rotation speed, that is, the first rotation speed; since the preset condition indicates that the imaging medium is about to enter the fixing unit, when it is detected that the position of the imaging medium meets the preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to change from the first rotation speed to the second rotation speed, thereby avoiding the pressure roller and the heating roller from being in a high-speed working state for a long time, and to a certain extent, improving the service life of the fixing unit.

[0011] In a possible implementation manner, the step of when the position of the imaging medium corresponding to the image forming job task meets a preset condition, controlling the rotation speeds of the pressure roller and the heating roller in the fixing unit to a second rotation speed includes:

[0012] Obtain a first distance corresponding to the imaging medium, where the first distance corresponding to the imaging medium is the distance along the movement trajectory of the imaging medium from the current position of the imaging medium to the imaging medium input port of the fixing unit;

[0013] Judge whether the first distance corresponding to the imaging medium matches a preset distance;

[0014] When the first distance corresponding to the imaging medium matches the preset distance, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to a second rotation speed.

[0015] In an embodiment of the present application, first obtain a first distance corresponding to the imaging medium; then judge whether the first distance corresponding to the imaging medium matches a preset distance; finally, when the first distance corresponding to the imaging medium matches the preset distance, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to a second rotation speed. It can be understood that since the first distance is the distance along the movement trajectory of the imaging medium from the current position of the imaging medium to the imaging medium input port of the fixing unit, by controlling the rotation speeds of the pressure roller and the heating roller in the fixing unit based on the magnitude relationship between the first distance and the preset distance, it can effectively avoid the pressure roller and the heating roller from being in a high-speed working state for a long time, and to a certain extent, improve the service life of the fixing unit.

[0016] In a possible implementation manner, the image forming device includes a transfer roller, and the transfer roller is used to transfer the toner pattern corresponding to the image forming job task to the imaging medium;

[0017] The preset distance is the distance between the transfer roller and the imaging medium input port of the fixing member along the movement track of the imaging medium.

[0018] In the embodiment of the present application, the preset distance is the distance between the transfer roller and the imaging medium input port of the fixing member along the movement track of the imaging medium. It can be understood that when it is detected that the toner pattern corresponding to the image forming operation task starts to be transferred to the imaging medium, the rotation speeds of the pressure roller and the heating roller in the fixing member are accelerated to the second rotation speed, so as to ensure the service life of the fixing member while ensuring that each imaging medium transferred with the toner pattern can be fully fixed.

[0019] In a possible implementation manner, when the position of the imaging medium corresponding to the image forming operation task meets a preset condition, controlling the rotation speeds of the pressure roller and the heating roller in the fixing member to be the second rotation speed includes:

[0020] When a preset time has elapsed after the image forming operation task is issued, controlling the rotation speeds of the pressure roller and the heating roller in the fixing member to be the second rotation speed, where the preset time represents that the position of the imaging medium corresponding to the image forming operation task meets the preset condition.

[0021] In the embodiment of the present application, when a preset time has elapsed after the image forming operation task is issued, controlling the rotation speeds of the pressure roller and the heating roller in the fixing member to be the second rotation speed. It can be understood that since the time when the ink dots corresponding to the image forming operation task on the transfer belt reach a fixed position can be evaluated, setting in advance to control the rotation speeds of the pressure roller and the heating roller in the fixing member to be the second rotation speed when a preset time has elapsed after the image forming operation task is issued can avoid the pressure roller and the heating roller being in a high-speed working state for a long time, improve the service life of the fixing member, and at the same time, since the adjustment of the rotation speeds of the pressure roller and the heating roller is achieved by timing and a position sensor is not required, the effect of saving devices and costs can be achieved.

[0022] In a possible implementation manner, the method further includes:

[0023] Determining a compensation distance between adjacent imaging media corresponding to the image forming operation task according to the fixing influencing factors; adjusting the distance between adjacent imaging media corresponding to the image forming operation task according to the compensation distance between adjacent imaging media corresponding to the image forming operation task.

[0024] In an embodiment of the present application, first, a compensation spacing between adjacent imaging media corresponding to an image forming operation task is determined according to fixing influencing factors, and then, according to the compensation spacing between adjacent imaging media corresponding to the image forming operation task, the spacing between adjacent imaging media corresponding to the image forming operation task is adjusted. It can be understood that the fixing influencing factors can reflect the life state of the fixing device. By adjusting the spacing between adjacent imaging media corresponding to the image forming operation task according to the fixing influencing factors, the adjusted spacing between adjacent imaging media corresponding to the image forming operation task is adapted to the life state of the fixing component, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the problem of fixing image ghosting and improving the imaging quality.

[0025] In a possible implementation manner, the method further includes:

[0026] Determine a target fixing temperature according to the fixing influencing factors;

[0027] Control the fixing temperature of the heating roller to be the target fixing temperature.

[0028] In an embodiment of the present application, first, a target fixing temperature is determined according to the fixing influencing factors; then, the fixing temperature of the heating roller is controlled to be the target fixing temperature. It can be understood that the fixing influencing factors can reflect the life state of the fixing device. By adjusting the fixing temperature according to the fixing influencing factors, the wear of the pressure roller and the heating roller is reduced, the service life of the fixing component is improved, and to a certain extent, the image ghosting of the imaging medium is avoided, and the imaging quality is improved.

[0029] In a possible implementation manner, the fixing influencing factors include at least one of: the cumulative fixing pages, the external environmental temperature, and the imaging medium type.

[0030] In an embodiment of the present application, the fixing influencing factors include at least one of: the cumulative fixing pages, the external environmental temperature, and the imaging medium type. It can be understood that by fully considering the environmental factors affecting the fixing operation of the fixing component, the compensation spacing between adjacent imaging media and the fixing temperature can be determined more accurately, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the problem of fixing image ghosting and improving the imaging quality.

[0031] In a second aspect, an embodiment of the present application provides an image forming apparatus, the image forming apparatus includes a fixing component, the fixing component includes a pressure roller and a heating roller, and the apparatus includes:

[0032] A first rotation speed control module, configured to control the rotation speeds of the pressure roller and the heating roller in the fixing component to be a first rotation speed in response to an issued image forming operation task;

[0033] A second rotation speed control module, configured to control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be a second rotation speed when the position of the imaging medium corresponding to the image forming operation task meets a preset condition, where the preset condition is used to indicate that the imaging medium is about to enter the fixing unit; the second rotation speed is the rotation speed of the pressure roller and the heating roller in the normal working state of the fixing unit; the first rotation speed is less than the second rotation speed.

[0034] In a third aspect, an embodiment of the present application provides an electronic device, which is characterized by including:

[0035] A processor;

[0050] For a better understanding of the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0051] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0052] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0053] It should be understood that the term " / and / " used herein is only a description of the associated relationship of the associated objects, indicating that there can be three relationships. For example, a and / or b can represent: a exists alone, a and b exist simultaneously, and b exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0054] For ease of understanding, the following first gives an exemplary description of a specific application scenario.

[0055] See Figure 1 , a schematic diagram of an application scenario provided by an embodiment of the present application. As Figure 1As shown, this application scenario includes: an image forming apparatus 101. Among them, the image forming apparatus 101 includes: a fixing member 102, printing paper 103, an intermediate transfer belt 104, and a paper cassette 105. Specifically, after the intermediate transfer belt 104 on the image forming apparatus 101 transfers the toner corresponding to the target image onto the printing paper 103, the fixing member 102 performs a fixing operation on the transferred imaging medium, thereby ensuring that the toner corresponding to the target image melts and is fixed onto the imaging medium. Among them, as Figure 1 The image forming apparatus shown also includes other functional structures, such as an ink cartridge, a photosensitive drum, and a charging roller, etc. For the sake of concise description, this application does not specifically elaborate on them here.

[0056] It should be noted that Figure 1 The image forming apparatus 101 and the printing paper 103 shown in

[0057] are only an exemplary description and should not be regarded as a limitation of the protection scope of this application. For example, the image forming apparatus 101 includes but is not limited to printers, copiers, fax machines, multifunctional image production and copying devices, electrophotographic printing devices, and any other similar devices. The printing paper 103 includes but is not limited to photos, papers, posters, and any other similar media.

[0057] For the convenience of understanding the fixing operation of the fixing member, refer to Figure 2 which is a schematic diagram of a fixing process scenario provided by the related art. As Figure 2 shown, this application scenario includes: a heating roller 201, a pressure roller 202, printing paper 203, cured toner 204, and unmelted toner 205. Specifically, the printing paper 203 moves to the left, and the unmelted toner 205 on the printing paper 203 is melted by the heating roller 201 and pressed by the pressure roller 202, so that the toner melts and is fixed onto the imaging medium 203.

[0058] To better understand the fixing member, this application also provides a schematic diagram of the structure of a fixing member. Specifically, refer to Figure 3 which is a schematic diagram of the structure of a fixing member provided by the related art. As shown in the figure, a heating roller 302 and a pressure roller 308 are shown. Among them, the heating roller 302 specifically includes: a support sheet metal 305, a support bracket 307, a ceramic heating sheet 304, a thermistor 306, a fixing film 303, and a fixing film bushing 301. Specifically, the heating roller is the source of fixing heat, and the pressure roller provides pressure under the action of an elastic member. The support sheet metal and the support bracket are mainly used to support the heating roller, the ceramic heating sheet is the source of heat generated by the heating roller, the fixing film is used to conduct the heat of the ceramic heating sheet to the medium, and the fixing film bushing is used to support the fixing film.

[0059] In the related art, under the action of high temperature and high pressure, the material life of the fixing member will be affected. As the number of printing fixings of the fixing member in the image forming apparatus increases, the fixing member will be worn to a certain extent.

[0060] Moreover, during the process from when the image forming apparatus receives an image forming job task to when the first page of the printed image forming job task is completed, the fixing member is mostly in an idling state, which will cause wear and tear of the life of the fixing member at this time.

[0061] When the pressure roller reaches the late stage of its life, the sponge material of the pressure roller is damaged, the material supportability becomes poor, and then the outer diameter contour curve of the pressure roller is damaged. At this time, continuing to fix the imaging medium will cause paper wrinkles. It can be understood that when the pressure roller is in the late stage of its life, in a long-term high temperature and high pressure working environment, the supportability of the silicone material of the pressure roller is damaged, and the problem of paper wrinkles will occur. Therefore, in actual use, the ineffective loss of the life of the fixing member should be avoided as much as possible.

[0062] In response to the above problems, in the embodiments of the present application, in response to the issued image forming job task, first control the rotation speeds of the pressure roller and the heating roller in the fixing member to be the first rotation speed; when the position of the imaging medium corresponding to the image forming job task meets a preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing member to be the second rotation speed. It can be understood that after the image forming job task is issued, the fixing member controls the pressure roller and the heating roller to maintain a lower rotation speed, that is, the first rotation speed; since the preset condition indicates that the imaging medium is about to enter the fixing member, when it is detected that the position of the imaging medium meets the preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing member to become the second rotation speed, thereby avoiding the pressure roller and the heating roller from being in a high-speed working state for a long time, and to a certain extent, improving the service life of the fixing member. Specifically, it will be described in detail below in conjunction with the drawings and specific embodiments.

[0063] See Figure 4 , which is a schematic flowchart of a fixing control method provided by an embodiment of the present application. This method can be applied to Figure 1 the application scenario shown in Figure 4 as shown, and it mainly includes the following steps.

[0064] Step S401: In response to the issued image forming job task, control the rotation speeds of the pressure roller and the heating roller in the fixing member to be the first rotation speed.

[0065] In an embodiment of the present application, in response to an issued image forming operation task, the rotation speeds of a pressure roller and a heating roller in a fixing unit are controlled to be a first rotation speed. Specifically, when the image forming apparatus detects an image forming operation task, the image forming apparatus controls the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the first rotation speed.

[0066] It can be understood that the first rotation speed is less than the movement speed of an imaging medium in a normal operating state of the image forming apparatus, that is, a second rotation speed. Of course, in a possible implementation manner, the first rotation speed can be 0, and the present application does not make specific limitations thereto.

[0067] Step S402: When the position of the imaging medium corresponding to the image forming operation task meets a preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed.

[0068] In an embodiment of the present application, when the position of the imaging medium corresponding to the image forming operation task meets a preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed. Among them, the preset condition is used to indicate that the imaging medium is about to enter the fixing unit; the second rotation speed is the rotation speed of the pressure roller and the heating roller in a normal operating state of the fixing unit; the first rotation speed is less than the second rotation speed.

[0069] It can be understood that after the image forming operation task is issued, the fixing unit will control the pressure roller and the heating roller to maintain a lower rotation speed, that is, the first rotation speed; since the preset condition indicates that the imaging medium is about to enter the fixing unit, when it is detected that the position of the imaging medium meets the preset condition, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to change from the first rotation speed to the second rotation speed, thereby avoiding the pressure roller and the heating roller from being in a high-speed operating state for a long time, and to a certain extent, improving the service life of the fixing unit.

[0070] Of course, in practical applications, in order to accurately control the rotation speeds of the pressure roller and the heating roller in the fixing unit, it is first necessary to accurately determine whether the imaging medium has run to a position that meets the preset condition. Specifically, the current position of the imaging medium can be directly detected by a sensor, and then it is determined whether the current position of the imaging medium meets the preset condition; or the current position of the imaging medium can be predicted based on existing conditions, and then it is determined whether the current position of the imaging medium meets the preset condition, etc.

[0071] Therefore, in a possible implementation manner, step S402 specifically includes steps S4021 - S4023. Details are as described below.

[0072] Step S4021: Obtain a first distance corresponding to the imaging medium.

[0073] In an embodiment of the present application, when the image forming apparatus detects an image forming job task, a first distance corresponding to the imaging medium is obtained. The first distance is the distance along the movement trajectory of the imaging medium from the current position of the imaging medium to the imaging medium input port of the fixing unit.

[0074] Exemplarily, when the current position of the imaging medium is in the paper tray, the corresponding first distance is the distance along the movement trajectory of the imaging medium from the paper outlet of the paper tray to the imaging medium input port of the fixing unit; when the current position of the imaging medium is at position A, the corresponding first distance is the distance along the movement trajectory of the imaging medium from position A to the imaging medium input port of the fixing unit.

[0075] It should be noted that the current position of the imaging medium described above, that is, position A, may specifically be the paper outlet position of the paper tray, the transfer position of the secondary transfer roller and the imaging medium, any position on the movement trajectory between the paper outlet position of the paper tray and the transfer position of the secondary transfer roller and the imaging medium, and any position on the movement trajectory between the transfer position of the secondary transfer roller and the imaging medium and the imaging medium input port of the fixing unit, etc. Those skilled in the relevant art can make adjustments according to the actual situation, and the present application does not make specific limitations thereto.

[0076] Step S4022: Determine whether the first distance corresponding to the imaging medium matches a preset distance.

[0077] In an embodiment of the present application, after the first distance is obtained, it is determined whether the first distance corresponding to the imaging medium matches a preset distance. It can be understood that when the first distance corresponding to the imaging medium matches the preset distance, step S4023 is executed, and specific reference is made to the following embodiments for description.

[0078] In a possible implementation manner, when the first distance corresponding to the imaging medium does not match the preset distance, the first distance corresponding to the imaging medium is obtained again to perform the matching between the first distance and the preset distance again.

[0079] Wherein, the "preset distance" described above is a distance preset by the user. In a possible implementation manner, when the image forming apparatus is a color printer, the preset distance may be the distance along the movement trajectory of the imaging medium from the secondary transfer roller to the imaging medium input port of the fixing unit; when the image forming apparatus is a black and white printer, the preset distance may be the distance along the movement trajectory of the imaging medium from the transfer roller to the imaging medium input port of the fixing unit.

[0080] It can be understood that when it is detected that the toner pattern corresponding to the image forming job task starts to be transferred to the imaging medium, the rotation speeds of the pressure roller and the heating roller in the fixing unit are controlled to accelerate to the second rotation speed, thereby ensuring the service life of the fixing unit while ensuring that each imaging medium transferred with the toner pattern can be fully fixed.

[0081] Step S4023: When the first distance corresponding to the imaging medium matches the preset distance, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed.

[0082] In the embodiment of the present application, when the first distance corresponding to the imaging medium matches the preset distance, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed. Wherein, the second rotation speed is the rotation speed of the pressure roller and the heating roller in the normal working state of the fixing unit, and the first rotation speed is less than the second rotation speed.

[0083] Specifically, along the movement track of the imaging medium, a corresponding sensor can be installed at a preset distance from the fixing unit. When it is detected that the imaging medium has passed by, start to control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed.

[0084] It can be understood that since the first distance is the distance from the current position of the imaging medium to the imaging medium input port of the fixing unit along the movement track of the imaging medium, therefore, based on the magnitude relationship between the first distance and the preset distance, controlling the rotation speeds of the pressure roller and the heating roller in the fixing unit can effectively prevent the pressure roller and the heating roller from being in a high-speed working state for a long time, and to a certain extent, improve the service life of the fixing unit.

[0085] In practical applications, since the position where the photosensitive drum in the Y color toner cartridge receives the light beam emitted by the laser scanning unit, the transfer position of the secondary transfer roller and the imaging medium, and the actual mechanical distance of the fixing unit are determined during the manufacture of the image forming apparatus, and at the same time, the speed of the transfer belt is generally constant, so the time corresponding to the position where the ink dots corresponding to the image forming job task reach the transfer roller can be evaluated.

[0086] Therefore, in a possible implementation manner, when a preset time has elapsed after the image forming job task is issued, control the rotation speeds of the pressure roller and the heating roller in the fixing unit to be the second rotation speed. Wherein, the preset time represents that the position of the imaging medium corresponding to the image forming job task meets the preset conditions.

[0087] Specifically, when the Y-color toner cartridge receives the light beam emitted by the laser scanning unit, the rotation speeds of the pressure roller and the heating roller in the fixing unit are controlled to be the first rotation speed; after a preset time period is timed, then the rotation speeds of the pressure roller and the heating roller in the fixing unit are controlled to be the second rotation speed. Specifically, the preset time period can be: the time point when the Y-color toner cartridge receives the light beam emitted by the laser scanning unit to the time point when the ink dot reaches the transfer position between the secondary transfer roller and the imaging medium. For example: when performing a certain image forming operation task, timing starts at the time point when the Y-color toner cartridge receives the light beam emitted by the laser scanning unit, and the rotation speeds of the pressure roller and the heating roller in the fixing unit are controlled to be the first rotation speed. After a preset time period T1, the rotation speeds of the pressure roller and the heating roller in the fixing unit are controlled to be the second rotation speed. Among them, T1 can be determined by the mechanical distance from the position where the Y-color toner cartridge receives the light beam emitted by the laser scanning unit to the transfer position between the secondary transfer roller and the imaging medium. Specifically, when performing an image forming operation task, the laser scanning unit emits a light beam, the Y-color toner cartridge receives the light beam emitted by the laser scanning unit, and the actual mechanical distances between the position where the Y-color toner cartridge receives the light beam, the secondary transfer roller, and the fixing unit are determined during the manufacture of the image forming apparatus. Therefore, by dividing the corresponding mechanical distance by the speed of the transfer belt, the time when the ink dot corresponding to the image forming operation task reaches the corresponding position can be estimated. The above solution is described using one of the toner cartridges. In addition to the Y-color toner cartridge, it is also possible to use the position where the photosensitive drum of any one of the other three color toner cartridges C / M / K receives the light beam emitted by the LSU as the starting point. The present application does not make specific limitations on this. The preset time period can also be: the time point when the Y-color toner cartridge receives the light beam emitted by the laser scanning unit to the time point when the ink dot corresponding to the image forming task reaches any other position. It should be noted that LSU is the laser scanning unit, and will not be elaborated below.

[0088] In another possible implementation, a corresponding sensor can be installed at the Y-color imaging position. When it is detected that there is toner on the transfer belt, among them, the secondary transfer roller, and the Y / M / C / K four-color toner cartridges described above are all components in a color printer. Of course, the method corresponding to the embodiments of the present application can also be applied to a black-and-white printer. The present application does not make specific limitations on this.

[0089] It should be pointed out that the above method embodiments are generally applied to the scenario where the image forming apparatus performs intermittent printing. Among them, intermittent printing means that the image forming apparatus performs a new image forming operation task at least after an interval of a period of time.

[0090] In practical applications, the hardness of the pressure roller in the fixing unit gradually decreases as the cumulative number of fixing pages increases, thereby increasing the width of the pressure area between the pressure roller and the heating roller. For the sake of easy understanding, on the basis of Figure 2 see Figure 5, which is a schematic diagram of another fusing process scenario provided by the embodiments of the present application. The width 501 of the pressure area between the pressure roller and the heating roller is also shown in the figure. It can be understood that during the operation of a general image forming apparatus, the pressure between the pressure roller and the heating roller is constant, but the hardness of the pressure roller changes. When the hardness of the pressure roller changes, the pressure roller will be pressed more downward, and the pressed area will be larger.

[0091] In practical applications, when the width of the pressure area between the pressure roller and the heating roller increases and the fusing speed remains unchanged, the fusing heating time of the imaging medium will increase, and thus the problem of image ghosting is likely to occur.

[0092] In view of the above problems, in the embodiments of the present application, a compensation distance between adjacent imaging media corresponding to an image forming operation task is determined according to the fusing influencing factors; and the distance between adjacent imaging media corresponding to the image forming operation task is adjusted according to the compensation distance between adjacent imaging media corresponding to the image forming operation task. It should be noted that adjusting the distance between adjacent imaging media corresponding to the image forming operation task refers to the distance between each page printed in the image forming operation task. For example, in a certain image forming operation task, the user issues a printing task of 100 pages. Then, in this image forming operation task, the distance between each page of paper needs to be adjusted according to the compensation distance.

[0093] In a specific implementation manner, the fusing influencing factor may be the cumulative number of fusing pages. Specifically, before controlling imaging, first determine whether the cumulative number of fusing pages is greater than or equal to a preset number of fusing pages; then when the cumulative number of fusing pages is greater than or equal to the preset number of fusing pages, determine the compensation distance between adjacent imaging media corresponding to the image forming operation task; finally, adjust the distance between adjacent imaging media corresponding to the image forming operation task according to the compensation distance between adjacent imaging media corresponding to the image forming operation task. It can be understood that the cumulative number of fusing pages can reflect the life state of the fusing device. According to the magnitude relationship between the cumulative number of fusing pages and the preset number of fusing pages, the distance between adjacent imaging media corresponding to the image forming operation task is adjusted, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fusing component, and to a certain extent avoiding the problem of fusing image ghosting and improving the imaging quality. This will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0094] See Figure 6 , which is a schematic flowchart of another fusing control method provided by the embodiments of the present application. This method can be applied to Figure 1 the application scenario shown in Figure 6 As shown, before controlling imaging, the embodiments of the present application further include the following steps.

[0095] Step S601: Determine whether the cumulative number of fusing pages is greater than or equal to a preset number of fusing pages.

[0096] In an embodiment of the present application, after receiving an image forming job task, the image forming apparatus first obtains the cumulative fixing pages; then, it determines whether the cumulative fixing pages are greater than or equal to a preset fixing page number. Wherein, the cumulative fixing pages are the total number of imaging media fixed by the fixing component.

[0097] To ensure accurate counting of the cumulative fixing pages, a power-off protection buffer space can be set in the image forming apparatus to store the cumulative fixing pages. Even if the image forming apparatus suddenly loses power, after the image forming apparatus is powered on again, it will continue to count based on the original cumulative fixing pages.

[0098] Step S602: When the cumulative fixing pages are greater than or equal to the preset fixing page number, determine the compensation distance between adjacent imaging media corresponding to the image forming job task.

[0099] In an embodiment of the present application, when the cumulative fixing pages are greater than or equal to the preset fixing page number, the compensation distance between adjacent imaging media corresponding to the image forming job task is determined. It can be understood that when the cumulative fixing pages are greater than or equal to the preset fixing page number, it indicates that the wear between the pressure roller and the heating roller may be relatively serious at this time, and the compensation distance between adjacent imaging media corresponding to the image forming job task can be determined at this time.

[0100] In a possible implementation manner, the user can preset a compensation distance. When the cumulative fixing pages are greater than or equal to the preset fixing page number, the compensation distance between adjacent imaging media corresponding to the image forming job task is determined as the preset compensation distance.

[0101] In an embodiment of the present application, first obtain the fixing influencing factors, and then according to the fixing influencing factors, the compensation distance between adjacent imaging media corresponding to the fixing influencing factors can be determined more accurately, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the problem of fixing image ghosting and improving the imaging quality.

[0102] It should be noted that, in a possible implementation manner, the fixing influencing factors include: the cumulative fixing pages, the external environmental temperature, and the imaging medium type. It can be understood that fully considering the environmental factors affecting the fixing operation of the fixing component can more accurately determine the compensation distance between adjacent imaging media and the fixing temperature, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the problem of fixing image ghosting and improving the imaging quality.

[0103] Further, in a possible implementation manner, according to the fixing influencing factors and the first preset relation table, the compensation distance between adjacent imaging media corresponding to the fixing influencing factors is determined. Wherein, the first preset relation table is a preset corresponding relation table between the fixing influencing factors and the compensation distance.

[0104] Exemplarily, as shown in Table 1, a first preset relation table provided by the present application is shown. When the fixing influencing factor is fixing influencing factor B, the compensation distance can be determined as compensation distance B according to fixing influencing factor B and Table 1; similarly, when the fixing influencing factor is fixing influencing factor A, the compensation distance can be determined as compensation distance A according to fixing influencing factor A and Table 1; similarly, by analogy, the present application does not make specific limitations thereto.

[0105] Table 1:

[0106]

[0107] In the embodiment of the present application, according to the fixing influencing factors and the first preset relation table, the compensation distance between adjacent imaging media corresponding to the fixing influencing factors can be determined more accurately, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the problem of fixing image ghosting and improving the imaging quality.

[0108] Since the fixing influencing factors may include: factors such as the cumulative fixing pages P, the external environment temperature H, and the imaging medium type T, etc., the compensation distance can also be determined jointly according to multiple fixing influencing factors. As shown in Table 2, another first preset relation table provided by the present application is shown. When the cumulative fixing pages are P1, the external environment temperature is H1, and the imaging medium type is T1, the compensation distance can be determined as compensation distance a according to Table 2; similarly, when the cumulative fixing pages are P2, the external environment temperature is H2, and the imaging medium type is T3, the compensation distance can be determined as compensation distance l according to Table 2; similarly, by analogy, the present application does not make specific limitations thereto.

[0109] Table 2:

[0110]

[0111] Step S603: Adjust the distance between adjacent imaging media corresponding to the image forming operation task according to the compensation distance between adjacent imaging media corresponding to the image forming operation task.

[0112] In the embodiment of the present application, the distance between adjacent imaging media corresponding to the image forming operation task is adjusted according to the compensation distance between adjacent imaging media corresponding to the image forming operation task.

[0113] Specifically, the image forming apparatus compensates the paper pitch initially set for the image forming apparatus with the retrieved compensation pitch. During the compensation process, the engine firmware in the image forming apparatus controls the paper feed clutch to open and close, and the clutch controls the paper feed roller to rotate. After the paper feed roller rotates one circle, it pauses for a period of time, and by extending the time interval of the paper feed clutch opening and closing, the distance between the imaging media is increased.

[0114] In the embodiment of the present application, the compensation pitch between adjacent imaging media corresponding to the image forming operation task is determined according to the fixing influencing factors; then, according to the compensation pitch between adjacent imaging media corresponding to the image forming operation task, the distance between adjacent imaging media corresponding to the image forming operation task is adjusted. It can be understood that the fixing influencing factors can reflect the life state of the fixing device. By adjusting the distance between adjacent imaging media corresponding to the image forming operation task according to the fixing influencing factors, the wear of the pressure roller and the heating roller is reduced, the service life of the fixing component is improved, and the problem of fixing image ghosting is avoided to a certain extent, and the imaging quality is improved.

[0115] In practical applications, when the width of the pressure area between the pressure roller and the heating roller increases and the fixing speed remains unchanged, the fixing heating time of the imaging medium will increase, which will easily lead to an increase in the heating time, making the imaging medium prone to ghosting, and ultimately resulting in low imaging quality.

[0116] To solve the above problems, in the embodiment of the present application, before controlling imaging, the target fixing temperature is determined according to the fixing influencing factors; then, the fixing temperature of the heating roller is controlled to be the target fixing temperature. It can be understood that the fixing influencing factors can reflect the life state of the fixing device. By adjusting the fixing temperature according to the fixing influencing factors, the wear of the pressure roller and the heating roller is reduced, the service life of the fixing component is improved, and the problem of imaging medium image ghosting is avoided to a certain extent, and the imaging quality is improved.

[0117] In a specific implementation manner, the fixing influencing factor can be the cumulative number of fixing pages.

[0118] The following will be described in detail with reference to the drawings and specific embodiments.

[0119] See Figure 7 , which is a schematic flowchart of another fixing control method provided by the embodiment of the present application. This method can be applied to Figure 1 the application scenario shown in Figure 7 As shown, before controlling imaging, the embodiment of the present application further includes the following steps.

[0120] Step S701: Determine whether the cumulative number of fixing pages is greater than or equal to the preset number of fixing pages.

[0121] In an embodiment of the present application, after receiving an image forming job task, the image forming apparatus first obtains the cumulative fixing pages; then, it determines whether the cumulative fixing pages are greater than or equal to a preset fixing page number. Herein, the cumulative fixing pages are the total number of imaging media fixed by the fixing member.

[0122] Step S702: When the cumulative fixing pages are greater than or equal to the preset fixing page number, determine the target fixing temperature.

[0123] In an embodiment of the present application, when the cumulative fixing pages are greater than or equal to the preset fixing page number, the target fixing temperature is determined. It can be understood that the cumulative fixing pages being greater than or equal to the preset fixing page number indicates that the wear between the pressure roller and the heating roller may be relatively serious at this time, the width of the pressure area between the pressure roller and the heating roller is relatively large, and thus the heating time of the imaging medium is increased. At this time, the target fixing temperature can be determined.

[0124] In a possible implementation manner, a user can preset a target fixing temperature. When the cumulative fixing pages are greater than or equal to the preset fixing page number, the target fixing temperature is determined as the preset target fixing temperature.

[0125] In a possible implementation manner, the fixing influencing factors can be obtained first; then, based on the fixing influencing factors, a more accurate target fixing temperature can be determined, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing member, and to a certain extent avoiding the image ghosting of the imaging medium and improving the imaging quality.

[0126] Further, in a possible implementation manner, according to the fixing influencing factors and the second preset relation table, the target fixing temperature corresponding to the fixing influencing factors is determined. Herein, the second preset relation table is a corresponding relation table between the fixing influencing factors and the target fixing temperature.

[0127] Exemplarily, as shown in Table 3, a second preset relation table provided by the present application is shown. When the fixing influencing factor is the fixing influencing factor B, the target fixing temperature B can be determined according to the fixing influencing factor B and Table 3; similarly, when the fixing influencing factor is the fixing influencing factor A, the fixing temperature A can be determined according to the fixing influencing factor A and Table 3; similarly, and so on, the present application does not make specific limitations thereto.

[0128] Table 3:

[0129]

[0130] Since the factors affecting fixing can include: the cumulative number of fixing pages P, the external environmental temperature H, and the type of imaging medium T, etc., the target fixing temperature can also be determined according to multiple factors affecting fixing. Table IV shows another second preset relationship table provided by this application. When the cumulative number of fixing pages is P1, the external environmental temperature is H1, and the type of imaging medium is T1, the target fixing temperature can be determined as target fixing temperature a according to Table IV; similarly, when the cumulative number of fixing pages is P2, the external environmental temperature is H2, and the type of imaging medium is T3, the target fixing temperature can be determined as target fixing temperature l according to Table IV; and so on. This application does not make specific restrictions on this.

[0131] Table IV:

[0132]

[0133] In the embodiments of this application, according to the factors affecting fixing and the second preset relationship table, a more accurate target fixing temperature corresponding to the factors affecting fixing can be determined, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the image ghosting of the imaging medium and improving the imaging quality.

[0134] Step S703: Control the fixing temperature of the heating roller to be the target fixing temperature.

[0135] In the embodiments of this application, after the target fixing temperature is determined, control the fixing temperature of the heating roller to be the target fixing temperature.

[0136] Specifically, after the target fixing temperature is determined, control the engine firmware of the image forming device to read the real-time temperature fed back by the thermistor on the fixing unit; then, according to the real-time temperature fed back by the thermistor, control the heating power of the ceramic sheet on the fixing unit to control the heating temperature of the heating roller, so as to ensure that when the imaging medium reaches the fixing component, the temperature of the heating roller reaches the target fixing temperature, thereby completing the control of the fixing temperature.

[0137] In the embodiments of this application, the cumulative number of fixing pages can reflect the life state of the fixing device. According to the size relationship between the cumulative number of fixing pages and the preset number of fixing pages, adjust the fixing temperature, thereby reducing the wear of the pressure roller and the heating roller, improving the service life of the fixing component, and to a certain extent avoiding the image ghosting of the imaging medium and improving the imaging quality.
