Description

Technical Field

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

[0002] When an image forming device executes 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 (eg, paper).

[0003] In the related art, before the image forming device starts to print the processed image on the image forming medium, the pickup roller rubs a sheet of paper so that the paper is transferred to the conveying roller so that the subsequent image forming device can perform the image forming operation. 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 sheet of 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, part of the image may be lost or the image forming operation may fail. In other words, the relevant technology cannot guarantee the imaging effect of presenting a larger image on a smaller image forming medium, thus affecting the user experience.

[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 paper pickup roller control method, an electronic device and a storage medium, so as to solve the problem in the prior art that it is impossible to ensure the imaging effect of presenting a larger image on a smaller image forming medium, thereby affecting the user experience.

[0007] In a first aspect, an embodiment of the present application provides a method for controlling a pickup roller, the method comprising:

[0008] Adjusting the opening time of the pickup roller according to the pickup roller control mode;

[0009] The pickup roller transfers at least one image forming medium to the transport roller according to the opening time.

[0010] In an embodiment of the present application, by adjusting the on-time of the pickup roller, the pickup roller can transfer at least one image forming medium to the transport roller. When the image size and the image forming medium size do not match, the image forming device adaptively adjusts the on-time of the pickup roller according to the pickup roller control mode selected by the user. The on-time of the pickup roller is flexibly adjusted according to the pickup roller control mode, so that at least one image forming medium can be transferred to the transport roller according to different situations. Therefore, a larger image can be directly printed on two or more smaller image forming media. When an image forming medium of a specific size is missing, image forming media of other sizes can be used as a substitute, so that the operating space of the image forming operation is larger, the user experience is stronger, and there is no need to segment the image data in advance, thereby saving time and space for image processing.

[0011] In a possible implementation, the pickup roller control mode includes:

[0012] User selected pickup roller control mode; or,

[0013] The pickup roller control mode is set by the factory in the image forming apparatus.

[0014] In an embodiment of the present application, a variety of pickup roller control modes can be provided for users to choose from, enriching the user's operating experience and expanding the scope of application of the pickup roller control method of the present application; of course, the pickup roller control mode can also be set at the factory to save user time.

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

[0016] According to the first transmission time and the second transmission time, adjusting the opening time of the pickup roller so that the opening time of the pickup roller is greater than or equal to the sum of the first transmission time and the second transmission time;

[0017] The second conveying time is the conveying time of the image forming medium from the pickup roller to the transport roller;

[0018] Wherein, when two sheets of image forming medium need to be conveyed to the conveying roller, the first conveying time is the conveying time of one sheet of the image forming medium passing through the pickup roller in the secondary scanning direction;

[0019] When more than three image forming media need to be conveyed to the transport roller, the first conveying time is the conveying time of at least two image forming media except the last image forming medium passing through the pickup roller in the sub-scanning direction.

[0020] In the embodiment of the present application, by determining the first transmission time and the second transmission time, the opening time of the pickup roller can be accurately determined, so as to accurately transmit the user's desired amount of image forming media to the image forming area, meeting the user's imaging needs.

[0021] In a possible implementation, adjusting the opening time of the pickup roller according to the first transmission time and the second transmission time so that the opening time of the pickup roller is greater than or equal to the sum of the first transmission time and the second transmission time includes:

[0022] A first conveying time of the image forming medium is calculated according to a length of the image forming medium in the sub-scanning direction corresponding to the pickup roller control mode and a conveying speed of the image forming medium.

[0023] In an embodiment of the present application, the first transmission time of the image forming medium is calculated based on the length of the image forming medium in the sub-scanning direction corresponding to the pickup roller control mode and the transmission speed of the image forming medium. By accurately determining the first transmission time, the opening time of the pickup roller can be accurately determined, thereby accurately transmitting the user's desired amount of image forming medium to the image forming area, meeting the user's imaging needs.

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

[0025] The pickup roller control device determines the first conveying time according to a corresponding relationship between the pickup roller control mode and the first conveying time.

[0026] In an embodiment of the present application, the first transmission time is determined based on the correspondence between the paper pickup roller control mode and the first transmission time, so there is no need to calculate the first transmission time every time, thereby improving the efficiency of obtaining the first transmission time, and then improving the efficiency of obtaining the paper pickup roller opening time, and ultimately starting paper pickup faster, thereby improving the user experience.

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

[0028] calculating a second conveying time of the image forming medium according to a conveying speed of the image forming medium and a distance between a pickup roller and a transport roller; or,

[0029] The second transfer time is a normal paper pickup time.

[0030] In the embodiment of the present application, not only can the second transmission time be obtained by calculation, but also the conventional paper rubbing time can be directly obtained as the second transmission time. Directly obtaining the conventional paper rubbing time as the second transmission time can save part of the calculation process, improve the efficiency of obtaining the second transmission time, and then improve the efficiency of obtaining the paper rubbing roller opening time, and finally start paper rubbing faster, thereby improving the user experience.

[0031] In a possible implementation, adjusting the opening time of the pickup roller according to the pickup roller control mode includes:

[0032] The pickup roller control device determines the turn-on duration of the pickup roller according to the corresponding relationship between the pickup roller control mode and the turn-on duration of the pickup roller.

[0033] In an embodiment of the present application, the on-time of the paper pickup roller can be determined based on the correspondence between the paper pickup roller control mode and the on-time of the paper pickup roller, thereby improving the efficiency of obtaining the on-time of the paper pickup roller. There is no need to calculate the first transmission time and the second transmission time, and ultimately paper pickup can be started faster, thereby improving the user experience.

[0034] In a possible implementation, adjusting the opening time of the pickup roller according to the pickup roller control mode includes:

[0035] The pickup roller opening time is adjusted according to the pickup roller control mode and the image size of the image forming job to be performed.

[0036] In the embodiment of the present application, the opening time of the pickup roller is not determined only according to the pickup roller control mode, so that the user can be prevented from forgetting to adjust or mistakenly adjusting the pickup roller control mode and causing paper pickup errors.

[0037] In a possible implementation, adjusting the pickup roller opening time according to the pickup roller control mode and the image size of the image forming job to be performed includes:

[0038] If the image size of the to-be-performed image forming job is larger than the image forming medium size corresponding to the pickup roller control mode, adjusting the opening time of the pickup roller according to the pickup roller control mode;

[0039] If the image size of the to-be-performed image forming job is smaller than or equal to the image forming medium size corresponding to the pickup roller control mode, the opening time length of the pickup roller is adjusted to a normal pickup time length.

[0040] In the embodiment of the present application, if the image size is larger than the image forming medium size, it is a case of presenting a large image on a small image forming medium. In this case, it is necessary to adjust the opening time of the paper pickup roller according to the paper pickup roller control mode; if the image size is less than or equal to the image forming medium size, it is a case of presenting a small image on a large image forming medium. In this case, it is only necessary to perform normal image forming operations and the paper pickup roller can pick up paper normally, which can prevent paper pickup errors caused by users forgetting to adjust or incorrectly adjusting the paper pickup roller control mode.

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

[0057] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are 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 specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0059] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0060] To facilitate understanding, the specific structure and working principle of the image forming device are first exemplarily described below.

[0061] See also Figure 1 , is a schematic diagram of the structure of the inside of a paper box of an image forming device provided in an embodiment of the present application. The image forming device is used to perform image forming tasks, such as generating, printing, receiving and sending image data, and examples of image forming devices include printers, scanners, copiers, fax machines, and multi-function peripherals (MFP, Multi-Functional Peripheral) that perform the above functions in a single device. Figure 1 As shown, the paper box of the image forming device includes a pickup roller 101, a conveying 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 paper 103 to convey the paper 103 to the conveying roller 102, and the conveying roller 102 conveys the paper 103 out of the paper box, so that the image forming device presents the image on the paper 103. It can be understood that in the conventional printing mode, the size of the image to be printed issued 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 conventional pickup time. In conventional printing, the pickup roller only needs to be opened for the conventional pickup time enough to convey the front end of the paper to the conveying roller. Since the front end of the paper has been conveyed to the conveying roller, at this time, regardless of whether the pickup roller is turned on or not, the paper can be conveyed to the imaging area only by turning on the conveying roller. Therefore, in conventional printing, the pickup roller only needs to be continuously opened for the conventional pickup time, and it is not necessary to continuously open the pickup roller until the entire part of the paper leaves the pickup roller. In the related art, the normal paper pickup time that allows a sheet of paper to be pulled off the paper pickup roller and transferred to the transport roller is the time stored in the memory in each image forming device. The normal paper pickup time is different for each model, and the unit is generally calculated in milliseconds, and the value is small.

[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. Exemplarily, 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. The present 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 has completed all image forming operations will eventually be transported to the paper discharge port for discharge under the transportation of the relevant roller structure. 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. However, when the image size is larger than the size of the image forming medium, if this method is still used, part of the image may be lost.

[0064] In response to the above problems, an embodiment of the present application provides a paper pickup roller control method, by adjusting the on time of the paper pickup roller so that the on time of the paper pickup roller can convey at least one image forming medium to the imaging area. For example, when the image size is twice the size of the paper, the on time of the paper pickup roller is adjusted so that the paper pickup roller can continuously convey 2 sheets of paper to the conveying roller. For another example, when the image size is 3 times the size of the paper, the on time of the paper pickup roller is adjusted so that the paper pickup roller can continuously convey 3 sheets of paper to the conveying roller. The on time of the paper pickup roller is flexibly adjusted according to the control mode of the paper pickup roller, so that at least one image forming medium can be conveyed to the conveying roller according to different situations. Therefore, when an image forming medium of a specific size is missing, image forming medium of other sizes can be used as a substitute, so that the operation space of the image forming operation is larger, the user experience is stronger, and there is no need to segment the image data in advance, thereby saving time and space for image processing.

[0065] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0066] See also Figure 2 , is a flow chart of a method for controlling a pickup roller provided in an embodiment of the present application. The method can be applied to Figure 1 The application scenario shown in Figure 1. Figure 2 As shown, it mainly includes the following steps.

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

[0068] Specifically, when the user sends an image to be executed for an image forming job, the user selects a pickup roller control mode at the same time, wherein each pickup roller control mode corresponds to an image forming medium size. In a possible implementation, the image forming device may be set with a pickup roller control mode when it leaves the factory. In this case, when the user sends an image to be executed for an image forming job, the user does not need to select a pickup roller control mode or only needs to check whether the current pickup roller control mode meets the imaging expectation.

[0069] In a possible implementation, the user can set a variety of pickup roller control modes on the panel of the image forming device or other control terminals. Exemplarily, the user selects mode 1 to print the image on two A4 sheets of paper, that is, the image forming medium size corresponding to mode 1 is A4, and the user selects mode 1, that is, the opening time of the pickup roller is adjusted to continuously rub 2 A4 sheets of paper to the image forming area for imaging operation; the user selects mode 2 to print the image on two A5 sheets of paper, that is, the image forming medium size corresponding to mode 2 is A5, and the user selects mode 2, that is, the opening time of the pickup roller is adjusted to continuously rub 2 A5 sheets of paper to the image forming area for imaging operation. The pickup roller control mode can also be a factory-provided setting of the image forming device, for example, the default setting of a certain model of image forming device when it leaves the factory is mode 1. Of course, the correspondence between the mode and the image forming medium is only an exemplary description. Those skilled in the art can set the correspondence between the mode and the image forming medium to other relationships according to actual needs, and the embodiments of the present application do not impose specific restrictions on this.

[0070] In addition, the control terminal is a terminal device that is communicatively connected to the image forming device, including but not limited to personal computers (PCs), mobile phones, tablet computers, personal digital assistants (PDAs), smart watches, netbooks, wearable electronic devices, augmented reality (AR) devices, virtual reality (VR) devices, vehicle-mounted devices, robots, smart glasses, etc.

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

[0072] See also Figure 3 , which is a schematic diagram of the continuous transmission process of paper between the pickup roller and the transport roller. Figure 3As shown, after the tail end of the paper 104 leaves the pickup roller 101, if the pickup roller 101 is in the open state at this time, the next paper 105 will be immediately rubbed out of the paper box and sent to the conveying roller after the tail end of the paper 104 leaves the pickup roller 101. After the front end of the paper 105 is sent to the conveying roller 102, the pickup roller 101 can be closed, and subsequently only the conveying roller 102 and other components need to be opened to convey the papers 104 and 105 to the image forming area. It should be noted that, when the paper 104 has not completely left the pickup roller 101, the conveying roller 102 is in the open state to convey the paper 104. At this time, even if the pickup roller is not opened, the paper 104 can be normally transported to the image forming area. Therefore, in the case where two sheets of paper need to be continuously conveyed to the image forming area, when the front end of the first sheet of paper has reached the conveying roller 102 and the tail of the first sheet of paper has not completely left the pickup roller 101, the pickup roller 101 can be opened or not. As long as the pickup roller 101 is opened when the tail of the first sheet of paper completely leaves the pickup roller 101, the second sheet of paper can be taken out of the paper box and conveyed to the conveying roller immediately following the first sheet of paper. For the convenience of control, the pickup roller 101 can be kept opened before the tail of the first sheet of paper completely leaves the pickup roller 101. When the pickup roller 101 is in contact with the first sheet of paper, even if the pickup roller 101 is in the open state, the second sheet of paper will not be pulled out of the paper box and sent to the conveying roller by friction. Only when the first sheet of paper completely leaves the pickup roller 101, the pickup roller 101 has the opportunity to contact the second sheet of paper and pull the second sheet of paper out of the paper box and send it to the conveying roller by friction. If three sheets of paper need to be continuously sent to the image forming area in one image forming operation, the pickup roller needs to be kept in the open state after the tail of the first sheet of paper leaves the pickup roller, and the second sheet of paper needs to be pulled out of the paper box and sent to the conveying roller by friction. After the tail of the second sheet of paper leaves the pickup roller, the pickup roller needs to be kept in the open state, and the third sheet of paper needs to be pulled out of the paper box and sent to the conveying roller by friction, thereby continuously sending the three sheets of paper to the conveying roller 102 and to the subsequent imaging area.

[0073] In a possible implementation, the opening time of the pickup roller is adjusted according to the first transmission time and the second transmission time, so that the opening time of the pickup roller is greater than or equal to the sum of the first transmission time and the second transmission time, wherein the second transmission time is the transmission time of the image forming medium from the pickup roller to the transport roller, and when two image forming media need to be transmitted to the transport roller, the first transmission time is the transmission time of one image forming medium passing through the pickup roller in the sub-scanning direction, and when more than three image forming media need to be transmitted to the transport roller, the first transmission time is the transmission time of at least two image forming media other than the last image forming medium passing through the pickup roller in the sub-scanning direction.

[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 pickup roller and the transport roller. Specifically, Figure 1 As shown, the distance between the edge of the pickup roller 101 that contacts the paper and the gap between the conveying roller 102 is the distance between the pickup roller and the conveying roller. 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 pickup roller and the conveying roller. For example, the second conveying time of the image forming medium can be calculated according to the formula The second transmission time of the image forming medium is calculated, wherein T2 is the second transmission time of the image forming medium corresponding to the pickup roller control mode, L2 is the distance between the pickup roller and the conveying roller, and v is the conveying speed of the image forming medium. In a possible implementation, the second transmission time may not be calculated in each image forming operation, but directly retrieved from the memory. Specifically, the second transmission time may be directly taken from the conventional pickup time. The second transmission time is the time required to pick up the paper from the paper box and transfer it to the conveying roller. Directly taking the conventional pickup time can reduce the calculation process and improve the calculation efficiency of the pickup roller opening time. For example, in a certain image forming job, the paper pickup roller control mode selected by the user is mode one (assuming that mode one corresponds to a mode of rubbing two A4 sheets of paper to the imaging area). The first transmission time of the A4 paper is obtained by calculation as T1=210÷265≈0.79s, and the second transmission time is not calculated by the distance between the paper pickup roller and the conveying roller, but directly uses the conventional paper pickup time stored in the memory of the image forming device, and then controls the opening time of the paper pickup roller to be greater than or equal to the sum of the first transmission time and the second transmission time (conventional paper pickup time), thereby transmitting the two A4 sheets of paper to the conveying roller.

[0075] In one possible implementation, the first conveying time of the image forming medium can be calculated based on the length of the image forming medium in the sub-scanning direction corresponding to the paper pickup 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] For example, when two image forming media need to be delivered to the conveying roller, the formula The first conveying time of the image forming medium is calculated, wherein T1 is the first conveying time, L1 is the length of the image forming medium in the sub-scanning direction corresponding to the pickup 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] For example, the size of A3 paper is 297mm×420mm, and the size of A4 paper is 210mm×297mm. In normal printing, only one A3 paper needs to be rubbed to the imaging area. At this time, the sub-scanning direction refers to the direction in which the 420mm long side of the A3 paper passes through the rubbing 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 rubbing roller to mode 1 (assuming that mode 1 corresponds to the mode of rubbing 2 A4 papers to the imaging area), the control time of the rubbing roller is required to rub 2 A4 papers to the imaging area. At this time, L1 of the A4 paper is 210mm (i.e. half of 420mm). It can be understood that when the user selects mode 1 and expects to print 1 A3 image on 2 A4 papers, the user will naturally put A The placement position of 4 papers on the paper box is adjusted so that the 210mm long side will be in the sub-scanning direction, so that when two A4 papers are conveyed to the image forming 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 impose specific restrictions on this.

[0078] In one possible implementation, when more than three image forming media need to be conveyed to the transport roller, the first conveying time is the conveying time of at least two image forming media except the last image forming medium through the pickup roller in the sub-scanning direction. The first conveying time of the image forming media is calculated based on the lengths of at least two image forming media in the sub-scanning direction corresponding to the pickup roller control mode and the conveying speed of the image forming media. The first conveying time is the conveying time of at least two image forming media through the pickup roller in the sub-scanning direction.

[0079] For example, when N sheets of image forming media need to be delivered to the conveying roller, the formula Calculate the first transmission time of the image forming medium, where T1 is the first transmission time, (N-1)L1 is the length of at least two image forming media corresponding to the pickup roller control mode in the sub-scanning direction, the sub-scanning direction is the transmission direction of the image forming medium, and v is the transmission speed of the image forming medium.

[0080] For example, the size of A3 paper is 297mm×420mm, and the size of a special type of X-type paper is 297mm×105mm. In conventional printing, only one A3 paper needs to be rubbed to the imaging area. At this time, the sub-scanning direction refers to the direction in which the 420mm long side of the A3 paper passes through the rubbing 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 rubbing roller to mode 1 (assuming that mode 1 corresponds to the mode of rubbing 4 X-type papers to the imaging area), the control time of the rubbing roller is required to rub 4 X-type papers to the imaging area. At this time, L1 of the X-type paper is 105mm (i.e., one quarter of 420mm). It can be understood that when the user selects mode 1 and expects to print one A3 image on four X-type papers, the user will naturally adjust the placement of the X-type paper on the paper box so that the 105mm long side will be in the sub-scanning direction, so that When 4 sheets of X-type paper are conveyed to the image forming area, the images formed by the 4 sheets of X-type paper can be spliced ​​into a complete A3 image. In some image forming devices, the conveying speed v of the image forming medium is 265 mm / s. Then, the first conveying time T1 corresponding to the 4 sheets of X-type paper in the image forming device is (4-1)×105÷265≈1.18 s. That is, the pickup roller needs to first open the first conveying time of 1.18 s to convey 3 sheets of paper to the conveying roller, and then open the second conveying time to convey the last sheet of paper to the conveying roller. Of course, this is only an exemplary description. For some image forming devices, v can also be 252.5 mm / s or 120 mm / s or other speeds, and the embodiments of the present application do not impose specific restrictions on this.

[0081] It can be understood that, through the method provided in the embodiment of the present application, the opening time of the pickup roller can be accurately adjusted, so that the number of papers expected by the user can be continuously transmitted to the image forming area, so that the image on the paper can fully present the effect expected by the user, and the image is not missing. In a possible implementation, the correspondence between the pickup roller control mode and the first transmission time can be pre-stored, and the pickup roller control device determines the first transmission time corresponding to the pickup roller control mode according to the pickup roller control mode and the correspondence between the pickup roller control mode and the first transmission time. The first transmission time is the transmission time of at least one image forming medium in the secondary scanning direction; according to the first transmission time and the second transmission time, the opening time of the pickup roller is adjusted so that the opening time of the pickup roller is greater than or equal to the sum of the first transmission time and the second transmission time. In a possible implementation, the correspondence between the image forming medium size and the first transmission time can be a comparison table between the image forming medium size and the first transmission time. For example, in a certain image forming operation, the pickup roller control mode selected by the user is mode 1 (assuming that mode 1 corresponds to a mode of rubbing two A4 sheets of paper to the imaging area). In the case where the correspondence between the pickup roller control mode and the first transmission time is pre-stored, the pickup roller control device can directly obtain the first transmission time corresponding to mode 1 as 0.79s. It can be understood that by looking up the first transmission time corresponding to the image forming medium size in a table, the image forming device can quickly obtain the first transmission time corresponding to the image forming medium size, thereby improving the calculation speed of the pickup roller opening time.

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

[0083] In the embodiment of the present application, the pickup roller control device adjusts the opening time of the pickup roller according to the first transmission time and the second transmission time. When the user inputs the image forming instruction, the pickup roller is turned on according to the opening time. It can be understood that the opening time of the pickup roller is determined only when there is an image to be executed for the image forming operation. When the opening time is determined, turning on the pickup roller can ensure that the image forming medium is timely and continuously delivered to the image scanning position, so as to perform the image forming operation.

[0084] In addition, when the pickup roller is turned on for a certain period of time, the pickup roller is turned off and turned on again before the next graphic forming operation. It can be understood that turning off the pickup roller in time after the current image forming medium is transferred to the conveying roller can save power and cost.

[0085] In one possible implementation, the correspondence between the pickup roller control mode and the on-time of the pickup roller can be pre-stored, and the pickup roller control device determines the on-time of the pickup roller corresponding to the pickup roller control mode according to the pickup roller control mode and the correspondence between the pickup roller control mode and the on-time of the pickup roller. According to the determined on-time of the pickup roller, the on-time of the pickup roller can transfer at least one image forming medium corresponding to the pickup roller control mode to the transport roller.

[0086] In a possible implementation, the correspondence between the pickup roller control mode and the turn-on time of the pickup roller can be a comparison table between the pickup roller control mode and the turn-on time of the pickup roller. Exemplarily, in a certain image forming operation, the pickup roller control mode selected by the user is mode 1 (assuming that mode 1 is to transfer 3 sheets of special paper type Y to the conveying roller), and the pickup roller control device determines that the turn-on time of the pickup roller corresponding to mode 1 is Z seconds based on the pickup roller control mode (mode 1) and the correspondence between the pickup roller control mode (mode 1) and the turn-on time of the pickup roller, that is, controlling the pickup roller to be turned on for Z seconds can transfer 3 sheets of Y type paper to the conveying roller.

[0087] It is understandable that pre-storing the correspondence between the pickup roller control mode and the pickup roller opening duration can save calculation time and improve the efficiency of obtaining the pickup roller opening duration. Corresponding to the above embodiment, the present application also provides another pickup roller control method.

[0088] See also Figure 4 , which is another paper pickup roller control method provided in the embodiment of the present application. This method can be applied to Figure 1 The application scenario shown in Figure 1. Figure 4 As 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, execute step S403; if no, execute step S407.

[0092] Step S403: according to the pickup roller control mode selected by the user, the size of the image forming medium is acquired, and according to the size of the image forming medium, the opening time of the pickup roller is adjusted.

[0093] Step S404: Turn on the pickup roller.

[0094] Step S405: delay time T1+T2.

[0095] Step S406: closing the pickup roller.

[0096] Step S407: End.

[0097] For specific contents involved in the embodiments of this application, please refer to the above Figure 2 and Figure 3 For the sake of brevity, the description in the illustrated embodiment will not be repeated here.

[0098] In a possible implementation, the pickup roller control device adjusts the pickup roller opening time not only according to the pickup roller control mode, but also according to the pickup roller control mode and the image size of the image forming job to be executed. In an actual usage scenario, if the user puts A4 paper in the paper box, and the user wants to print an A3-sized portrait to be printed, the user naturally sets the pickup roller control mode to mode 1 (assuming that mode 1 is a mode of conveying two A4 papers to the transport roller and to the image forming area). However, after printing the A3-sized portrait to be printed, The user may forget to adjust mode 1 back to the normal printing mode, which may result in the next printing, the user may want to print an A4-sized portrait to be printed, but because the user forgot to set the print mode back to the normal printing mode, the paper pickup roller control mode at this time is still the printing mode of sending 2 A4 papers to the transport roller. That is to say, if the paper pickup roller opening time is adjusted only according to the paper pickup roller control mode, the paper pickup roller control device will send the 2 A4 papers to the image forming area for imaging, and printing the 1 A4 portrait sent down on 2 A4 papers obviously does not meet the user's expected effect.

[0099] Therefore, the paper pickup roller opening time can be adjusted according to the paper pickup roller control mode and the image size of the image forming job to be performed. Specifically, the paper pickup roller control device obtains the image size of the image forming job to be performed, and then compares the image size of the image forming job to be performed and the paper size corresponding to the currently set paper pickup roller control mode. If the image size of the image forming job to be performed is larger than the paper size corresponding to the paper pickup roller control mode, the paper pickup roller opening time is adjusted according to the paper pickup roller control mode. If the image size of the image forming job to be performed is less than or equal to the paper size corresponding to the paper pickup roller control mode, normal printing is performed, that is, only the paper pickup roller is controlled to be turned on for a normal paper pickup time to remove a sheet of paper from the paper box and transmit it to the transport roller.

[0100] For example, in a certain image forming job, the user sets the paper pickup roller control mode to mode two (assuming that mode two is a mode of picking up two A5 papers from the paper box and transferring them to the conveying roller). The image size of the image forming job to be executed obtained by the paper pickup roller control device is A5. Since the image size of the image forming job to be executed at this time is less than or equal to the paper size corresponding to the paper pickup roller control mode, the opening time of the paper pickup roller is not controlled according to the paper pickup roller control mode. Instead, the opening time of the paper pickup roller is controlled to be only the normal paper pickup time, that is, only one A5 paper is picked up from the paper box and transferred to the conveying roller. For another example, in a certain image forming job, the user sets the paper pickup roller control mode to mode two (assuming that mode two is a mode in which two A5 papers are picked up from the paper box, conveyed to the transport roller, and then picked up to the image forming area). The image size of the image forming job to be executed obtained by the paper pickup roller control device is A4. Since the image size of the image forming job to be executed is larger than the paper size corresponding to the paper pickup roller control mode, the time length of the paper pickup roller is adjusted according to the paper pickup roller control mode. That is, the opening time length of the paper pickup roller is adjusted to the time length required to pick up two A5 papers from the paper box and convey them to the transport roller.

[0101] Step S202: According to the opening time, the pickup roller conveys at least one image forming medium to the image forming area. Specifically, when the pickup roller time is adjusted according to the pickup roller control mode, the pickup roller can rub at least one image forming medium to the image forming area according to the pickup time. It can be understood that after the opening time of the pickup roller is determined, the pickup roller control device can convey the corresponding image forming medium to the conveying roller according to the opening time of the pickup roller, so as to form an image in at least one image forming device.

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

[0103] To address this problem, there are two solutions in the related art. One is to prompt the user that the job is set incorrectly or the paper is placed incorrectly when the image forming medium size is small, stop the image forming job, and let the user reset it before executing the image forming job again; the other is to directly present the large-size image on the small-size image forming medium when the image forming medium size is small.

[0104] Because when the image forming device performs an image forming operation on an image, the duration of the fixing device being turned on is related to the length of the image in the secondary scanning direction, and the range of the fixing device being turned on is related to the length of the image in the main scanning direction. If the second solution mentioned above is adopted, the fixing device may be turned on for a longer time and in a larger range. However, due to the small size of the image forming medium, the image forming medium cannot take away the heat from the fixing device, causing the heat at both ends of the fixing device to accumulate and be unable to be consumed. Also, because the sensors 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, it will not trigger a high temperature alarm. Therefore, using the second solution mentioned above to continuously perform multiple-page image forming operations may cause problems such as overheating of the fixing device and adhesion of the fixing film, and there are safety hazards such as burning of the fixing device or even fire of the fixing device.

[0105] In order to solve this problem, an embodiment of the present application provides a fixing control method.

[0106] See also Figure 5 , is a flow chart of a fixing control method provided in an embodiment of the present application. Figure 5 As shown, it mainly includes the following steps.

[0107] Step S501: Start.

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

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

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

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

[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 prompt information.

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

[0116] Specifically, the setting about prompt information input by the user is received, which is specifically used to set whether to output prompt information when the image size is inconsistent with the image forming medium size, and the prompt information is used to prompt the user that the image size is inconsistent with the image forming medium size.

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

[0118] Step S508: When the image size is inconsistent with the image forming medium size, output a prompt message.

[0119] Step S509: End.

[0120] The first fixing mode and the second fixing mode will be described in detail later and will not be described again here.

[0121] In actual applications, after the user sets the image size of the image forming job, it is sent to the image forming device. After receiving the image forming job, the image forming device obtains the length of the image in the sub-scanning direction (hereinafter referred to as the image length) L3, and simultaneously obtains the medium spacing D1 corresponding to the image, wherein the medium spacing 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, which is used to control the opening time of the paper pickup roller.

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

[0123] See also Figure 6 , is a schematic diagram of a process flow of a first fixing mode provided in an embodiment of the present application. Figure 6 As shown, it mainly includes the following steps.

[0124] Step S601: Start.

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

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

[0127] Step S603: The pickup roller starts to work.

[0128] Specifically, when the image forming device starts to perform an image forming job, the pickup roller starts to work to ensure that the image forming medium reaches the image forming area in time and forms an image on the image forming medium.

[0129] Step S604: Calculate 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 apparatus, and the size of the image forming medium can be obtained through 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 through the sensor in the sub-scanning direction, and the actual length L4 of the image forming medium in the sub-scanning direction can be obtained by combining this time interval with the conveyance speed of the image forming medium.

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

[0132] If so, execute Step S607 and Step S608; if not, execute Step S606. Specifically, S is a preset control parameter threshold. If L4 < L3 - S, it can be determined that the size of the image forming medium is smaller than the image size; if L4 ≥ L3 - S, it can be determined that the size of the image forming medium is greater than or equal to the image size.

[0133] Step S606: Execute the normal image forming operation process.

[0134] Step S607: Increase 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, continuous heating of the fixing device can be avoided, sufficient heat dissipation time can be reserved for the fixing device, and problems such as overheating of the fixing device, adhesion of the fixing film, and even burnout of the fixing device can be avoided.

[0136] Step S608: Determine whether to output a prompt message. If so, execute Step S509; if not, execute Step S511.

[0137] Step S609: Output a prompt message.

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

[0139] Step S611: End.

[0140] The specific content involved in the embodiments of the present application can be referred to the description in the above Figure 5 illustrated embodiments. For the sake of brevity of expression, it will not be elaborated here.

[0141] Through Figure 6The method provided by the illustrated embodiment can eliminate the need for secondary manual operations by the user during the image forming process, thereby satisfying the user's need to present a large-size image on a small-size image forming medium, and can also reserve sufficient heat dissipation time for the fixing device by increasing the medium spacing, thereby avoiding problems such as overheating of the fixing device, adhesion of the fixing film, or even burning of the fixing device.

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

[0143] See also Figure 7 , is a schematic diagram of a flow chart of a second fixing mode provided in an embodiment of the present application. Figure 7 As shown, it mainly includes the following steps.

[0144] Step S701: Start.

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

[0146] Step S703: The pickup roller starts to work.

[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: Pause the remaining images of the image forming job for which paper pickup has not yet started.

[0152] Step S708: The picked-up image forming medium is discharged normally to the paper discharge box.

[0153] Step S709: output prompt information.

[0154] Specifically, taking printing as an example, the prompt message is "paper type is inconsistent, do you want to continue printing?" Of course, this prompt message is only an exemplary description, and those skilled in the art can set the prompt message to other forms according to actual needs, and the embodiment of the present application does not specifically limit this.

[0155] Step S710: Determine whether the user selects the [Confirm] key or the [Cancel] key.

[0156] If the user selects the [Confirm] key, step S712 is executed; if the user selects the [Cancel] key, step S711 is executed.

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

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

[0159] Step S713: Continue the operation at the medium spacing and operation speed corresponding to the length L4.

[0160] Step S714: End.

[0161] For specific contents involved in the embodiments of this application, please refer to the above Figure 5 and Figure 6 For the sake of brevity, the description in the illustrated embodiment will not be repeated here.

[0162] Understandable, through Figure 7 The embodiment shown can prompt the user in time that the image forming job setting is incorrect. If it is not the user's intention, the job can be canceled in time to avoid wasting resources due to misplaced image forming media resulting in size mismatch. In addition, if the user chooses to continue the image forming job, the actual image forming media size is updated to match, and the image forming job can be performed at a normal media spacing and operating speed to avoid overheating of the fixing device.

[0163] Corresponding to the above embodiments, the present application also provides an electronic device.
