Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image forming, in particular to a paper roller control method, an electronic device and a storage medium. BACKGROUND

[0002] When an image forming device performs a printing job, it usually first receives an image input by a user, processes the image, and finally prints the processed image on an image forming medium (for example, paper).

[0003] In the related art, before the image forming device starts printing the processed image on the image forming medium, the paper roller rolls one sheet of paper, so that the paper is conveyed to the conveying roller, to facilitate the subsequent image forming device to perform the image forming job. When the image size is the same as the size of the image forming medium, this method can make the image appear completely on one image forming medium.

[0004] However, when the image size is larger than the size of the image forming medium, if this method is still used, it may cause part of the image to be lost or the image forming job to fail. That is, the related art cannot guarantee the imaging effect of presenting a larger size image on a smaller size image forming medium, thereby affecting the user's experience.

[0005] It should be noted that the information disclosed in the background section of the present application is only intended to deepen the understanding of the general background of the present application, and should not be regarded as acknowledging or implying in any form that the information constitutes prior art known to those skilled in the art. SUMMARY

[0008] adjusting the opening duration of the paper roller according to the paper roller control mode;

[0009] According to the opening duration, the paper roller conveys at least one image forming medium to the conveying roller.

[0010] In the embodiments of the present application, the opening duration of the paper roller is adjusted, so that the paper roller can convey at least one image forming medium to the conveying roller. When the image size and the image forming medium size do not match, the image forming device adaptively adjusts the opening duration of the paper roller according to the paper roller control mode selected by the user, flexibly adjusts the opening duration of the paper roller according to the paper roller control mode, so that at least one image forming medium can be conveyed to the conveying roller according to different situations. Therefore, a larger image can be directly printed on two or more smaller image forming media, and when a specific size of image forming medium is missing, other sizes of image forming media can be used as a substitute, so that the operation space of the image forming operation is larger, the user experience is stronger, and the image data does not need to be segmented in advance, thereby saving the time and space of image processing.

Of course, the paper roller control mode can also be set at the factory to save the user's time.

[0015] In a possible implementation, the adjusting the opening duration of the paper roller according to the paper roller control mode includes:

[0016] According to the first conveying time and the second conveying time, the opening duration of the paper roller is adjusted to be greater than or equal to the sum of the first conveying time and the second conveying time.

[0017] The second conveying time is the conveying time of the image forming medium between the paper roller and the conveying roller;

[0019] When it is required to convey three or more image forming media to the conveying roller, the first conveying time is the conveying time of at least two image forming media in front of the last image forming medium in the sub-scanning direction through the paper roller.

[0020] In the embodiments of the present application, by determining the first conveying time and the second conveying time, the opening duration of the paper roller can be accurately determined, so that the user desired number of image forming media can be accurately conveyed to the image forming area, meeting the user's demand for imaging.

[0022] According to the length of the image forming medium in the sub-scanning direction corresponding to the paper roller control mode and the conveying speed of the image forming medium, the first conveying time of the image forming medium is calculated.

[0023] In the embodiments of the present application, the first conveying time of the image forming medium is calculated according to the length of the image forming medium in the sub-scanning direction corresponding to the paper roller control mode and the conveying speed of the image forming medium, and the opening duration of the paper roller can be accurately determined by accurately determining the first conveying time, so that the user desired number of image forming media can be accurately conveyed to the image forming area, meeting the user's demand for imaging.

[0024] In a possible implementation, the adjusting the opening duration of the paper roller according to the first conveying time and the second conveying time, so that the opening duration of the paper roller is greater than or equal to the sum of the first conveying time and the second conveying time, comprises:

[0025] The paper roller control device determines the first conveying time according to the correspondence between the paper roller control mode and the first conveying time.

[0026] In the embodiments of the present application, the first conveying time is determined according to the correspondence between the paper roller control mode and the first conveying time, so that the first conveying time does not need to be calculated every time, the acquisition efficiency of the first conveying time is improved, and the acquisition efficiency of the opening duration of the paper roller is improved, so that the paper can be started faster, and the user experience is improved.

[0027] In a possible implementation, the adjusting the opening duration of the paper roller according to the first conveying time and the second conveying time, so that the opening duration of the paper roller is greater than or equal to the sum of the first conveying time and the second conveying time, comprises:

[0028] According to the conveying speed of the image forming medium and the distance between the paper roller and the conveying roller, the second conveying time of the image forming medium is calculated; or,

[0029] The second conveying time is a conventional paper feeding duration.

[0030] In the embodiments of the present application, the second conveying time can be obtained by calculation, and the second conveying time can also be directly obtained as a conventional paper rolling duration. Directly obtaining the conventional paper rolling duration as the second conveying time can save part of the calculation process, improve the efficiency of obtaining the second conveying time, and further improve the efficiency of obtaining the opening duration of the paper roller, so that the paper rolling can be started faster, and the user experience is improved.

[0056] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0057] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0058] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" 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.

[0059] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0060] In order to facilitate understanding, the specific structure and working principle of the image forming device will be described first.

[0061] Referring to Figure 1 A structural schematic diagram of the paper box inside an image forming device provided for the embodiments of the present application. The image forming device is used to perform image forming jobs, such as generating, printing, receiving and sending image data, and examples of the image forming device include printers, scanners, copiers, fax machines, and multi-functional peripherals (MFPs) that perform the above functions in a single device. As shown inFigure 1 As shown, the paper tray of the image forming device includes a pickup roller 101, a transport roller 102, and a paper 103. When the image forming device performs an image forming operation, the pickup roller 101 relies on the friction between the paper 103 and the transport roller 102 to transport the paper 103. The transport roller 102 then transports the paper 103 out of the paper tray so that the image forming device can present the image on the paper 103. It can be understood that in a normal printing mode, the size of the image to be printed sent by the driver is consistent with the size of the image forming medium. In this case, the opening time of the pickup roller 101 only needs to be controlled to the normal pickup time. In normal printing, the pickup roller only needs to be opened for the normal pickup time to transport the front end of the paper to the transport roller. Since the front end of the paper has already been transported to the transport roller, at this time, regardless of whether the pickup roller is opened or not, the paper can be transported to the imaging area only when the transport roller is opened. Therefore, in normal printing, the pickup roller only needs to be opened for the normal pickup time, and does not need to be opened until the entire portion of the paper leaves the pickup roller. In related technologies, the normal paper pickup time required to pull a sheet of paper off the pickup roller and transfer it to the transport roller is the time stored in the memory of each image forming device. The normal paper pickup time for each specific model is different, and the unit is generally calculated in milliseconds, which is a small value.

[0062] It can be understood that the interior of the paper box of the image forming device listed above is only an example, and the component composition and component arrangement of the interior of the paper box of the image forming device can be adjusted according to actual conditions without affecting the improvement ideas of the present invention.

[0063] In the related art, when the image forming device performs an image forming operation on an image, the pickup roller rubs the paper so that the paper is conveyed to the transport roller, thereby conveying the paper to the image forming area so that the image forming device can perform the image forming operation. For example, after the paper is conveyed to the transport roller, it will be conveyed to the transfer area by the corresponding mechanism, that is, it will be conveyed to the relative area between the transfer roller and the photosensitive drum for transfer. In some image forming devices that can perform color printing, the transfer area may refer to the relative area between the transfer belt and the transfer roller. This application does not impose specific restrictions on this. The transfer roller absorbs the toner forming the image on the transfer belt or the photosensitive drum onto the paper, thereby transferring the image formed on the transfer belt or the photosensitive drum to the paper. After the image forming medium completes the transfer in the transfer area, it will be conveyed to the fixing area for fixing, so that the heated toner image is fixed on the paper. The image forming medium that completes all image forming operations will eventually be transported to the paper discharge port under the transportation of the relevant roller structure. When the image size is the same as the image forming medium, this method can be used to fully display the image on a single sheet of image forming medium. However, if the image size is larger than the image forming medium, using this method may result in partial loss of the image.

[0064] To solve the above problems, the embodiment of the present application provides a paper roller control method. The opening time of the paper roller is adjusted so that at least one image forming medium can be conveyed to the imaging area. For example, when the image size is twice the size of the paper, the opening time of the paper roller is adjusted so that the paper roller can continuously convey two sheets of paper to the conveying roller. For another example, when the image size is three times the size of the paper, the opening time of the paper roller is adjusted so that the paper roller can continuously convey three sheets of paper to the conveying roller. The opening time of the paper roller is flexibly adjusted according to the paper roller control mode, so that at least one image forming medium can be conveyed to the conveying roller according to different situations. Therefore, when the image forming medium of a specific size is missing, other sizes of image forming medium can be used as a substitute, so that the operation space of the image forming operation is larger, the user experience is stronger, and the image data does not need to be divided in advance, thereby saving the time and space of image processing.

[0065] In the following, detailed description is made in combination with the drawings and specific embodiments.

[0066] Reference is made to Figure 2 A flowchart of a paper roller control method provided by the embodiment of the present application is shown. The method can be applied to Figure 1 the application scenario shown. As shown in Figure 2 , it mainly includes the following steps.

[0067] Step S201: Adjust the opening time of the paper roller according to the paper roller control mode.

[0068] Specifically, when the user issues an image to be executed for image forming operation, the paper roller control mode is selected at the same time. Each paper roller control mode corresponds to an image forming medium size. In one possible implementation, the image forming device can be set with the paper roller control mode when it is manufactured. In this case, when the user issues an image to be executed for image forming operation, the paper roller control mode does not need to be selected or only needs to be checked whether the current paper roller control mode meets the imaging expectation.

[0069] In a possible implementation, the user can set multiple paper roller control modes on the panel of the image forming device or other control terminal. For example, the user selects mode one to print an image on two A4 papers, that is, the image forming medium size corresponding to mode one is A4, and the user selects mode one to adjust the opening duration of the paper roller to continuously roll two A4 papers to the image forming area for imaging operation; the user selects mode two to print an image on two A5 papers, that is, the image forming medium size corresponding to mode two is A5, and the user selects mode two to adjust the opening duration of the paper roller to continuously roll two A5 papers to the image forming area for imaging operation. The paper roller control mode can also be a factory setting of the image forming device, for example, the default setting of a certain model of image forming device when it is shipped from the factory is mode one. Of course, the correspondence between the mode and the image forming medium is only an example, and those skilled in the art can set the correspondence between the mode and the image forming medium according to actual needs, and the embodiments of the present application do not make specific limitations thereto.

[0070] In addition, the control terminal is a terminal device in communication connection with the image forming device, including but not limited to a personal computer (PC), a mobile phone, a tablet computer, a personal digital assistant (PDA), a smart watch, a netbook, a wearable electronic device, an augmented reality (AR) device, a virtual reality (VR) device, a vehicle-mounted device, a robot, smart glasses, etc.

[0071] After the user selects one of the paper roller control modes on the panel of the image forming device or other control terminal, the paper roller control device can adjust the opening duration of the paper roller according to the paper roller control mode, so that the opening duration of the paper roller can roll at least one image forming medium to the image forming area.

[0072] Referring to Figure 3 , a schematic diagram of the continuous conveying process of the paper between the paper roller and the conveying roller is shown. As shown in Figure 3As shown, after the trailing end of the paper 104 leaves the pinch roller 101, if the pinch roller 101 is in the open state at this time, the next paper 105 will be pinched away from the paper cassette and conveyed to the conveying roller immediately after the trailing end of the paper 104 leaves the pinch roller 101. The leading end of the paper 105 is conveyed to the conveying roller 102, and then the pinch roller 101 can be closed. Subsequently, only the opening of the conveying roller 102 and other components can convey the papers 104 and 105 to the image forming area. It should be particularly noted that when the paper 104 has not completely left the pinch roller 101, the conveying roller 102 is in the open state to convey the paper 104. At this time, even if the pinch roller is not opened, the paper 104 can be normally conveyed to the image forming area. Therefore, in the case of continuously conveying two papers to the image forming area, when the leading end of the first paper has reached the conveying roller 102 and the trailing end of the first paper has not completely left the pinch roller 101, the pinch roller 101 can be opened or not opened at this time. As long as the pinch roller 101 is in the open state when the trailing end of the first paper completely leaves the pinch roller 101, the second paper can be pinched away from the paper cassette and conveyed to the conveying roller immediately after the trailing end of the first paper completely leaves the pinch roller 101. In order to facilitate control, the pinch roller 101 can be kept open before the trailing end of the first paper completely leaves the pinch roller 101. However, at this time, the pinch roller 101 is in contact with the first paper. Even if the pinch roller 101 is in the open state at this time, the second paper cannot be pinched away from the paper cassette and conveyed to the conveying roller by the friction force. Only when the first paper completely leaves the pinch roller 101, the pinch roller 101 has the opportunity to contact the second paper and convey the second paper away from the paper cassette and to the conveying roller by the friction force. If it is required to continuously convey three papers to the image forming area in one image forming operation, the pinch roller needs to be kept in the open state after the trailing end of the first paper leaves the pinch roller, so as to pinch the second paper away from the paper cassette and convey the second paper to the conveying roller by the friction force. After the trailing end of the second paper leaves the pinch roller, the pinch roller is kept in the open state, so as to pinch the third paper away from the paper cassette and convey the third paper to the conveying roller by the friction force. Thus, the three papers are continuously conveyed to the conveying roller 102 and to the subsequent image forming area.

[0073] In a possible implementation, according to the first conveying time and the second conveying time, the opening duration of the pinch roller is adjusted so that the opening duration of the pinch roller is greater than or equal to the sum of the first conveying time and the second conveying time. The second conveying time is the conveying time of the image forming medium between the pinch roller and the conveying roller. When it is required to convey two image forming media to the conveying roller, the first conveying time is the conveying time of one image forming medium in the sub-scanning direction through the pinch roller. When it is required to convey more than three image forming media to the conveying roller, the first conveying time is the conveying time of at least two image forming media in front of the last image forming medium in the sub-scanning direction through the pinch roller.

[0074] In a possible implementation, the second conveying time of the image forming medium is calculated according to the conveying speed of the image forming medium and the distance between the paper roller and the conveying roller. Figure 1 As shown in FIG. 10, the distance between the edge of the paper roller 101 in contact with the paper and the middle gap of the conveying roller 102 is the distance between the paper roller and the conveying roller, and the second conveying time of the image forming medium is calculated according to the conveying speed of the image forming medium and the distance between the paper roller and the conveying roller. Exemplarily, the second conveying time of the image forming medium can be calculated according to the formula , wherein T2 is the second conveying time of the image forming medium corresponding to the paper roller control mode, L2 is the distance between the paper roller and the conveying roller, and v is the conveying speed of the image forming medium. In a possible implementation, the second conveying time can also not be calculated in each image forming operation, but be directly called from the memory. Specifically, the second conveying time can be directly the conventional paper feeding time, and the second conveying time is the time required for the paper to be fed from the paper cassette to the conveying roller. Directly using the conventional paper feeding time can reduce the calculation process and improve the calculation efficiency of the opening time of the paper roller. For example, in an image forming operation, the user selects the paper roller control mode as mode one (assuming that mode one corresponds to the mode of feeding two A4 papers to the imaging area), the first conveying time T1 of the A4 paper is calculated as 210 ÷ 265 ≈ 0.79 s, and the second conveying time is not calculated according to the distance between the paper roller and the conveying roller, but directly uses the conventional paper feeding time stored in the memory of the image forming device, and then controls the opening time of the paper roller to be greater than or equal to the sum of the first conveying time and the second conveying time (the conventional paper feeding time), so as to convey two A4 papers to the conveying roller.

[0075] In a possible implementation, the first conveying time of the image forming medium can be calculated according to the length of the image forming medium in the sub-scanning direction corresponding to the paper roller control mode and the conveying speed of the image forming medium, wherein the sub-scanning direction is the conveying direction of the image forming medium, and the conveying speed of the image forming medium is determined by the image forming device.

[0076] Exemplarily, when two image forming media need to be conveyed to the conveying roller, the first conveying time of the image forming medium can be calculated according to the formula , wherein T1 is the first conveying time, L1 is the length of the image forming medium in the sub-scanning direction corresponding to the paper roller control mode, the sub-scanning direction is the conveying direction of the image forming medium, and v is the conveying speed of the image forming medium. In addition,

[0077] Exemplarily, the size of A3 paper is 297mm*420mm, and the size of A4 paper is 210mm*297mm. In a conventional printing, only one A3 paper is needed to be fed to the imaging area, at this time, the sub-scanning direction refers to the 420mm long side of the A3 paper through the direction of the paper feeding roller, that is, the length of the A3 paper in the sub-scanning direction is 420mm, when the user sets the control mode of the paper feeding roller to mode one (assuming that mode one corresponds to the mode of feeding two A4 papers to the imaging area), at this time, the control time length of the paper feeding roller needed to feed two A4 papers to the imaging area can feed two A4 papers to the imaging area, at this time, the L1 of the A4 paper is 210mm (that is, half of 420mm), it can be understood that when the user selects mode one and expects to print one A3 image on two A4 papers, the user will naturally adjust the placement position of the A4 paper on the paper cassette to make the 210mm long side in the sub-scanning direction, so that when the two A4 papers are conveyed to the imaging area, the images formed by the two A4 papers can be spliced into a complete A3 image, in some image forming devices, the conveying speed v of the image forming medium is 265mm / s, then the first conveying time T1 of the A4 paper in the image forming device is 210÷265≈0.79s, of course, this is only an exemplary description, for some image forming devices, v can also be 252.5mm / s or 120mm / s or other speeds, and the embodiments of the present application do not make specific limitations thereto.

[0078] In a possible implementation, when it is needed to convey more than three image forming media to the conveying roller, the first conveying time is the conveying time of at least two image forming media in front of the last image forming medium in the sub-scanning direction through the paper feeding roller, according to the length of at least two image forming media in the sub-scanning direction corresponding to the control mode of the paper feeding roller and the conveying speed of the image forming medium, the first conveying time of the image forming medium is calculated, and the first conveying time is the conveying time of at least two image forming media in the sub-scanning direction through the paper feeding roller.

[0079] Exemplarily, when it is needed to convey N image forming media to the conveying roller, the first conveying time of the image forming medium can be calculated according to the formula , wherein T1 is the first conveying time, (N-1)L1 is the length of at least two image forming media in the sub-scanning direction corresponding to the control mode of the paper feeding roller, the sub-scanning direction is the conveying direction of the image forming medium, and v is the conveying speed of the image forming medium.

[0080] For example, the size of an A3 paper is 297mm x 420mm, and the size of a special type X paper is 297mm x 105mm. In a normal printing process, only one A3 paper is needed to be fed to the imaging area, at this time, the sub-scanning direction refers to the 420mm long side of the A3 paper, and the length of the A3 paper in the sub-scanning direction is 420mm. When the user sets the control mode of the paper feeding roller to mode one (assuming that mode one corresponds to the mode of feeding four X papers to the imaging area), the control time of the paper feeding roller is needed to feed four X papers to the imaging area, at this time, the L1 of the X paper is 105mm (i.e. one fourth of 420mm). It can be understood that when the user selects mode one to expect to print one A3 image on four X papers, the user will naturally adjust the placement position of the X paper in the paper cassette to make the 105mm long side of the X paper in the sub-scanning direction, so that when the four X papers are conveyed to the imaging area, the images formed by the four X papers can be spliced into a complete A3 image. In some image forming devices, the conveying speed v of the image forming medium is 265mm / s, and the first conveying time T1 corresponding to the four X papers in the image forming device is (4-1) x 105 ÷ 265≈1.18s, that is, the paper feeding roller needs to be opened for a first conveying time of 1.18s to convey three papers to the conveying roller, and then a second conveying time is opened to convey the last paper to the conveying roller. Of course, this is only an example description, and for some image forming devices, v can also be 252.5mm / s or 120mm / s or other speeds, and the embodiments of the present application do not make specific limitations thereto.

[0081] It can be understood that, by the method provided in the embodiments of the present application, the opening duration of the paper roller can be accurately adjusted, so that the user-desired number of paper sheets can be continuously conveyed to the image forming area, and thus the image on the paper sheet can be completely presented in the user-desired effect without missing the image. In a possible implementation, a corresponding relationship between the paper roller control mode and the first conveying time can be pre-stored, the paper roller control device determines the first conveying time corresponding to the paper roller control mode according to the paper roller control mode and the corresponding relationship between the paper roller control mode and the first conveying time, the first conveying time being the conveying time of at least one image forming medium in the sub-scanning direction; and the opening duration of the paper roller is adjusted according to the first conveying time and the second conveying time, so that the opening duration of the paper roller is greater than or equal to the sum of the first conveying time and the second conveying time. In a possible implementation, the corresponding relationship between the image forming medium size and the first conveying time can be a comparison table between the image forming medium size and the first conveying time. For example, in a certain image forming operation, the user-selected paper roller control mode is mode one (assuming that mode one corresponds to a mode of rolling 2 A4 paper sheets to the imaging area), and in the case that the corresponding relationship between the paper roller control mode and the first conveying time is pre-stored, the paper roller control device can directly obtain the first conveying time corresponding to mode one, which is 0.79s. It can be understood that, by searching the corresponding first conveying time corresponding to the image forming medium size in the table, the image forming device can quickly obtain the first conveying time corresponding to the image forming medium size, thereby improving the calculation speed of the opening duration of the paper roller.

[0082] Of course, the above table is only an exemplary description, and should not be regarded as a limitation on the protection scope of the present application, and those skilled in the art can set the corresponding relationship between the image forming medium size and the first conveying time and the corresponding relationship between the second conveying time and the image forming medium to other formats according to actual needs.

[0083] In the embodiments of the present application, the paper roller control device adjusts the opening duration of the paper roller according to the first conveying time and the second conveying time. When the user inputs the image forming instruction, the paper roller is opened according to the opening duration. It can be understood that, when there is an image to be executed in the image forming operation, the opening duration of the paper roller is determined, and when the opening duration is determined, the paper roller is opened to ensure that the image forming medium is timely and continuously conveyed to the image scanning position for the execution of the image forming operation.

[0084] In addition, when the opening time of the paper roller reaches the opening duration, the paper roller is closed and opened before the next image forming operation. It can be understood that, the paper roller is closed in a timely manner after the current image forming medium is conveyed to the conveying roller, which can save electric energy and reduce costs.

[0085] In a possible implementation, a correspondence between the paper roller control mode and the opening duration of the paper roller can be stored in advance, the paper roller control device determines the opening duration of the paper roller corresponding to the paper roller control mode according to the paper roller control mode and the correspondence between the paper roller control mode and the opening duration of the paper roller, and enables the opening duration of the paper roller to convey at least one image forming medium corresponding to the paper roller control mode to the conveying roller according to the determined opening duration of the paper roller.

[0086] In a possible implementation, the correspondence between the paper roller control mode and the opening duration of the paper roller can be a comparison table between the paper roller control mode and the opening duration of the paper roller. For example, in an image forming operation, the paper roller control mode selected by the user is mode one (assuming that mode one is to convey three special Y-type papers to the conveying roller), the paper roller control device determines the opening duration of the paper roller corresponding to mode one as Z seconds according to the paper roller control mode (mode one) and the correspondence between the paper roller control mode (mode one) and the opening duration of the paper roller, that is, controlling the paper roller to open for Z seconds can convey three Y-type papers to the conveying roller.

[0087] It can be understood that the correspondence between the paper roller control mode and the opening duration of the paper roller stored in advance can save calculation time and improve the efficiency of obtaining the opening duration of the paper roller. Corresponding to the above embodiment, the present application further provides another paper roller control method.

[0088] Referring to Figure 4 Another paper roller control method provided by the embodiment of the present application. The method can be applied to Figure 1 the application scenario as shown in the figure. As Figure 4 shown, it mainly includes the following steps.

[0089] Step S401: Start.

[0090] Step S402: Determine whether there is an image to be printed.

[0091] If yes, perform step S403; if no, perform step S407.

[0092] Step S403: According to the paper roller control mode selected by the user, obtain the image forming medium size, and adjust the opening duration of the paper roller according to the image forming medium size.

[0093] Step S404: Open the paper roller.

[0094] Step S405: Delay for a duration of T1+T2.

[0095] Step S406: Close the paper roller.

[0096] Step S407: End.

[0097] The specific content involved in the embodiments of the present application can be referred to the description in the above Figure 2 and Figure 3 The description in the embodiments shown above, and for the sake of brevity, will not be described again.

[0098] In a possible implementation, the paper roller control device not only adjusts the paper roller opening duration according to the paper roller control mode, but also adjusts the paper roller opening duration according to the paper roller control mode and the image size of the image forming job to be executed. In a real use scenario, if the user puts A4 paper in the paper box, and the user wants to issue a print of an A3 size to-be-printed image, the user naturally sets the paper roller control mode to mode one (assuming that mode one is a mode of conveying two A4 papers to the conveying roller and conveying to the image forming area), but after printing the A3 size to-be-printed image, the user may forget to adjust mode one back to the regular printing mode, which may cause that in the next printing, the user may want to issue a print of an A4 size to-be-printed image, but the user forgets to set the printing mode back to the regular printing mode, and at this time, the paper roller control mode is still the printing mode of conveying two A4 papers to the conveying roller, that is, if the paper roller opening duration is only adjusted according to the paper roller control mode, the paper roller control device will convey two A4 papers to the image forming area for imaging, and print the issued one A4 image on two A4 papers, which obviously does not meet the user's expectation.

[0099] Therefore, the paper roller opening duration can be adjusted according to the paper roller control mode and the image size of the image forming job to be executed. Specifically, the paper roller control device acquires the image size of the image forming job to be executed, and then compares the image size of the image forming job to be executed with the paper size corresponding to the currently set paper roller control mode. If the image size of the image forming job to be executed is greater than the paper size corresponding to the paper roller control mode, the paper roller opening duration is adjusted according to the paper roller control mode. If the image size of the image forming job to be executed is less than or equal to the paper size corresponding to the paper roller control mode, regular printing is performed, that is, the paper roller is only controlled to be opened for a regular paper roller duration, and one paper is rubbed off the paper box and conveyed to the conveying roller.

[0100] For example, in an image forming operation, the user sets the paper roller control mode to mode two (assuming that mode two is a mode of rolling two A5 papers away from the paper cassette and conveying to the conveying roller), and the image size of the image forming operation to be performed obtained by the paper roller control device is A5. Since the image size of the image forming operation to be performed is less than or equal to the paper size corresponding to the paper roller control mode, the opening duration of the paper roller is not controlled according to the paper roller control mode, but is controlled to be only the conventional paper rolling duration, that is, only one A5 paper is rolled away from the paper cassette and conveyed to the conveying roller. For another example, in an image forming operation, the user sets the paper roller control mode to mode two (assuming that mode two is a mode of rolling two A5 papers away from the paper cassette and conveying to the conveying roller and rolling to the image forming area), and the image size of the image forming operation to be performed obtained by the paper roller control device is A4. Since the image size of the image forming operation to be performed is greater than the paper size corresponding to the paper roller control mode, the duration of the paper roller is adjusted according to the paper roller control mode, that is, the opening duration of the paper roller is adjusted to a duration in which two A5 papers can be rolled away from the paper cassette and conveyed to the conveying roller.

[0101] In step S202, the paper roller conveys at least one image forming medium to the image forming area according to the opening duration. Specifically, after the duration of the paper roller is adjusted according to the paper roller control mode, the paper roller can roll at least one image forming medium to the image forming area according to the paper rolling duration. It can be understood that after the opening duration of the paper roller is determined, the paper roller control device can convey the corresponding image forming medium to the conveying roller according to the opening duration of the paper roller, so as to form an image on the at least one image forming device.

[0102] In actual applications, if the user selects the wrong paper roller control mode, the user places the wrong paper size in the paper cassette, or the user needs to present a large-size image on a small-size paper, the image forming device may not be able to normally perform the image forming operation.

[0103] To solve this problem, there are two solutions in the related art. One is to prompt the user to set the operation incorrectly or to place the paper incorrectly when the image forming medium size is small, stop the image forming operation, and let the user set it again before performing the image forming operation. The other is to directly present a large-size image on a small-size image forming medium when the image forming medium size is small.

[0104] Because the length of the opening of the fixing device is related to the length of the image in the sub-scanning direction and the opening range of the fixing device is related to the length of the image in the main scanning direction when the image forming device performs the image forming operation on the image, if the second solution is used, the length of the opening of the fixing device may be long and the range may be large, but because the size of the image forming medium is small, the image forming medium cannot take away the heat on the fixing device, so that the heat at both ends of the fixing device cannot be consumed and accumulates, and because the sensor in some fixing devices can only detect the temperature of the heating tube and cannot detect the temperature at both ends of the fixing device, even if the temperature at both ends of the fixing device is too high, a high-temperature alarm will not be triggered. Therefore, using the second solution to continuously perform a plurality of image forming operations may cause the fixing device to overheat, the fixing film to adhere, and the like, and there is a risk of burning out the fixing device and even the fixing device catching fire.

[0105] To solve the problem, an embodiment of the present application provides a fixing control method.

[0106] Referring to Figure 5 , a flowchart of a fixing control method provided by an embodiment of the present application is shown. As shown in Figure 5 , it mainly includes the following steps.

[0107] Step S501: Start.

[0108] Step S502: Obtain the fixing control mode set by the user.

[0109] Specifically, the user can set the image forming device and select the fixing control mode of the image forming device when the image size does not match the image forming medium size.

[0110] Step S503: Determine whether the fixing control mode set by the user is the first fixing control mode.

[0111] If yes, step S505 is performed; if no, step S504 is performed.

[0112] Step S504: The fixing control mode is the second fixing control mode.

[0113] Step S505: The fixing control mode is the first fixing control mode.

[0114] Step S506: Determine whether to output a prompt message.

[0115] If yes, step S508 is performed; if no, step S507 is performed.

[0116] Specifically, a user input regarding setting of prompt information is received, specifically for setting whether to output prompt information for prompting the user that the image size is inconsistent with the image forming medium size when the image size is inconsistent with the image forming medium size.

[0117] Step S507: no prompt information when the image size is inconsistent with the image forming medium size.

[0118] Step S508: output prompt information when the image size is inconsistent with the image forming medium size.

[0119] Step S509: end.

[0120] Wherein, the first fixing mode and the second fixing mode are described in detail hereinafter, which will not be repeated here.

[0121] In actual application, when the user sets the image size of the image forming job and issues it to the image forming device, the image forming device receives the image forming job, acquires the length (hereinafter referred to as image length) L3 of the image in the sub-scanning direction, and acquires the medium pitch D1 corresponding to the image, wherein the medium pitch refers to the distance between the tail end of the image forming medium of the previous page in the sub-scanning direction and the head end of the image forming medium of the next page in the sub-scanning direction, for controlling the opening time of the paper roller.

[0122] The first fixing mode is described in detail below.

[0123] Referring to Figure 6 , a flowchart of a first fixing mode provided by an embodiment of the present application is shown. As Figure 6 indicated, it mainly includes the following steps.

[0124] Step S601: start.

[0125] Step S602: receive the image forming job set by the user, and the image length L3.

[0126] Specifically, the image forming job set by the user not only includes the image, but also includes the fixing mode selected by the user, and in the embodiment of the present application, the fixing mode selected by the user is the first fixing mode. Wherein, the image length L3 can be acquired from the print driver end.

[0127] Step S603: the paper roller starts working.

[0128] Specifically, when the image forming device starts to execute the image forming job, the paper roller starts working, ensuring that the image forming medium reaches the image forming area in time, and the image is formed on the image forming medium.

[0129] Step S604: calculating the actual length L4 of the image forming medium.

[0130] Specifically, the actual length of the image forming medium is the length of the image forming medium in the sub-scanning direction. There are various sensors in the image forming device, and the size of the image forming medium can be obtained by any one of the sensors. Specifically, the sensors respectively record the time when the leading end and the trailing end of a certain page of the image forming medium pass the sensors, and the actual length L4 of the image forming medium in the sub-scanning direction can be obtained by the time interval combined with the conveying speed of the image forming medium.

[0131] Step S605: judging whether L4 is less than L3-S.

[0132] If yes, steps S607 and S608 are executed; if no, step S606 is executed. Specifically, S is a preset control parameter threshold value, if L4 < L3-S, it is determined that the size of the image forming medium is less than the image size; if L4 ≥ L3-S, it is determined that the size of the image forming medium is greater than or equal to the image size.

[0133] Step S606: executing the normal image forming job flow.

[0134] Step S607: increasing the medium spacing of the remaining job pages to the medium spacing corresponding to the length L4.

[0135] It can be understood that by increasing the medium spacing, the fixing device can be prevented from being continuously heated, and sufficient heat dissipation time is reserved for the fixing device, thereby avoiding problems such as overheating of the fixing device, adhesion of the fixing film, and even burning of the fixing device.

[0136] Step S608: judging whether to output a prompt information, if yes, step S509 is executed; if no, step S511 is executed.

[0137] Step S609: outputting the prompt information.

[0138] Step S610: continuing to execute the image forming job at the speed corresponding to the length L4.

[0139] Step S611: ending.

[0140] The specific contents involved in the embodiments of the present application can be referred to the descriptions in the above Figure 5 embodiments for brevity, which will not be described herein.

[0141] The specific contents involved in the embodiments of the present application can be referred to the descriptions in the above Figure 6The method provided by the embodiment shown can meet the requirement of the user for presenting a large-size image on a small-size image forming medium without secondary manual operation of the user during the image forming operation, and can also reserve sufficient heat dissipation time for the fixing device by enlarging the medium spacing, so as to avoid problems such as overheating of the fixing device, adhesion of the fixing film, and even burning of the fixing device.

[0142] In addition, the embodiment of the present application further provides an image forming operation process in a second fixing mode.

[0143] Referring to Figure 7 , a flowchart of the second fixing mode provided by the embodiment of the present application is shown. As Figure 7 shown, it mainly includes the following steps.

[0144] Step S701: Start.

[0145] Step S702: Receive the image forming operation set by the user, image length L3.

[0146] Step S703: Start work of the paper feed roller.

[0147] Step S704: Calculate the actual length L4 of the image forming medium.

[0148] Step S705: Determine whether L4 is less than L3-S.

[0149] If yes, execute step S707; if no, execute step S706.

[0150] Step S706: Normal printing process.

[0151] Step S707: Suspend the image forming operation of the image which has not started to be fed.

[0152] Step S708: Normally discharge the image forming medium which has been fed to the paper tray.

[0153] Step S709: Output the prompt information.

[0154] Specifically, taking printing as an example, the prompt information is "paper type inconsistency, whether to continue printing". Of course, the prompt information is only an example, and those skilled in the art can set the prompt information into other forms according to actual needs, and the embodiment of the present application does not make specific limitation on this.

[0155] Step S710: Determine whether the user selects the [confirm] key or the [cancel] key.

[0156] If the user selects the [confirm] key, execute step S712; if the user selects the [cancel] key, execute step S711.

[0157] Step S711: cancel the image forming job, and stop the job.

[0158] Step S712: update the image length of the remaining image of the image forming job to L4.

[0159] Step S713: continue the job with the medium interval and the job speed corresponding to the length L4.

[0160] Step S714: end.

[0161] The specific content involved in the embodiments of the present application can refer to the description in the above Figure 5 and Figure 6 embodiments. For the sake of brevity, the description will not be repeated.

[0162] It can be understood that, through the embodiments shown in Figure 7 , the user can be prompted in time that the image forming job is set incorrectly. If it is not the user's intention, the job can be cancelled in time to avoid wasting resources due to the mismatch of the size caused by the wrong image forming medium. In addition, if the user chooses to continue to execute the image forming job, the actual image forming medium size is updated, and the image forming job can be performed with normal medium interval and job speed, so as to avoid overheating of the fixing device.
