Description

Technical Field

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

[0002] Since the paper needs to go through two transfers during the printing process, the first transfer is to transfer the toner from the photosensitive drum to the transfer belt, and the second transfer is to transfer the toner from the transfer belt to the paper. During continuous printing, the first sheet of paper will enter the fixing assembly after leaving the secondary transfer, and the second sheet of paper will start the primary transfer at this time.

[0003] When the printer is printing continuously in a cold environment, the pressure roller is in a contracted state, and a higher temperature is required for fixing. When the head of the first sheet of paper passes through the fixing component, the paper is bent and piled at the end of the transfer belt. When the tail of the paper is pulled out, the load of the transfer belt is suddenly reduced, which will cause the transfer belt speed to increase, and then the first transfer speed of the second sheet of paper is increased. When the second sheet of paper undergoes the second transfer, the transfer belt speed has returned to the default speed. This will cause the speed of the two transfers of the second sheet of paper to be inconsistent, and the position of the toner transfer to the paper will change, which will eventually lead to poor color registration.

[0004] When printing with a hot machine in a high-temperature environment, the pressure roller expands due to the heat but the rotation speed remains unchanged, causing the paper to be straightened after the paper head passes through the fixing component. Due to being straightened, the tail of the first sheet of paper will not accumulate at the end of the transfer belt, that is, the load of the paper tail escaping from the transfer belt becomes smaller, the transfer belt speed changes very little, and the color registration situation is improved.

[0005] In the prior art, in order to solve the problem of poor color registration, it is necessary to add additional sensors on the basis of the existing printer, and use the additional sensors to collect the outer diameter of the roller and change the rotation speed of the fixing motor according to the outer diameter of the roller. However, the additional sensors added to collect the outer diameter of the roller will increase the parts of the printer, resulting in increased costs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fixing motor control method, an image forming device, and a storage medium, which do not require any sensor to measure the outer diameter of the roller and then adjust the fixing motor speed, thereby saving costs.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] The embodiment of the present invention provides an image forming device, including but not limited to a printer, a copier, a fax machine, a scanner, and a multifunction machine integrating printing, copying, faxing, scanning and other functions, etc., whose function is to print images or texts on imaging media.

[0049] See also Figure 1 , is a schematic diagram of an application scenario provided by an embodiment of the present invention. As an example of an image forming device 100, the image forming device 100 includes photosensitive drums 101Y-K (i.e., 101Y, 101M, 101C, and 101K), charging rollers 102Y-K (i.e., 102Y, 102M, 102C, and 102K), developing rollers 103Y-K (i.e., 103Y, 103M, 103C, and 103K), powder bins 104Y-K (i.e., 104Y, 104M, 104C, and 104K), a transfer belt 105, a secondary transfer roller 106, a laser scanning unit (LSU, Laser Scanning Unit) 107, a heat roller 108, a pressure roller 109, a discharge roller 110, and a discharge paper box 111. Generally speaking, the process box YK includes a photosensitive drum 101Y-K, a charging roller 102Y-K, a developing roller 103Y-K and a powder bin 104Y-K for containing toner.

[0050] When the image forming apparatus is printing, the charging rollers 102Y-K (i.e., 102Y, 102M, 102C, and 102K) will continuously cover the photosensitive drums 101Y-K (i.e., 101Y, 101M, 101C, and 101K) with a layer of negative charge during rotation, and remove the residual charge from the previous cycle.

[0051] The laser scanning unit (LSU) 107 emits a laser beam to illuminate the portion of the photosensitive drums 101Y-K (i.e., 101Y, 101M, 101C, and 101K), which causes a discharge phenomenon and a latent image to appear on the drum surface of the photosensitive drums 101Y-K (i.e., 101Y, 101M, 101C, and 101K).

[0052] The developing roller 103Y-K (i.e., 103Y, 103M, 103C, and 103K) attracts the charged toner in the toner cartridge 104Y-K to the surface through a magnet in the center. When the toner on the surface of the developing roller 103Y-K contacts the photosensitive drum 101Y-K, the toner is transferred to the drum surface of the photosensitive drum 101Y-K to form an image.

[0053] The image forming device further includes a paper box (not shown in the figure), which is used to place paper. When printing, the image forming device sends the paper placed in the paper box into the paper path.

[0054] The image forming device further includes a secondary transfer roller 106. When a sheet of paper is fed between the secondary transfer roller 106 and the transfer belt 105, the secondary transfer roller 106 absorbs the toner forming the image on the transfer belt 105 onto the sheet of paper, thereby transferring the image formed on the transfer belt 105 onto the sheet of paper.

[0055] The image forming device also includes a heat roller 108 and a pressure roller 109 that constitute a fixing component. The heat roller 108 heats the toner image on the paper fed between the heat roller 108 and the pressure roller 109, and while heating, the pressure roller 109 applies pressure to the heat roller 108 to fix the heated toner image on the paper. The image forming device also includes a fixing motor (not shown), and the image forming device drives the pressure roller 109 to rotate through the fixing motor.

[0056] The image forming device also includes a powder bin 104Y-K and a cleaning sheet (not shown in the figure). The cleaning sheet removes excess toner from the drum surface of the photosensitive drum 101Y-K and collects it into the powder bin 104Y-K to prevent excess toner from leaking onto the paper surface.

[0057] The image forming device also includes an environment detector (not shown), which detects the environment in which the image forming device is currently located in real time to obtain environmental parameters, wherein the environment detector includes at least one of a temperature sensor and a humidity sensor, and correspondingly, the environmental parameters include at least one of a temperature parameter and a humidity parameter. Of course, if the image forming device is not provided with an environment detector, it can be obtained from a host computer (such as a computer, a mobile phone) through a communication module, or sent to the image forming device by an operator through the host computer.

[0058] When the ambient temperature is low and the internal temperature of the image forming apparatus is low, the printing of the image forming apparatus is cold printing. Since the internal temperature of the image forming apparatus is currently low, a higher temperature is required for fixing.

[0059] In contrast to cold printing, when the ambient temperature is high and the internal temperature of the image forming apparatus is high, the printing of the image forming apparatus is hot printing, which does not require such a high temperature (lower temperature than cold printing) for fixing.

[0060] When the image forming apparatus is in cold start printing, the pressure roller 109 is in a tightened state. When the pressure roller 109 is in a tightened state, the outer diameter of the pressure roller 109 is smaller than that of the pressure roller in the expanded state. Then, when the angular velocity of the pressure roller remains unchanged, the linear velocity during cold start printing is relatively smaller than that during hot start printing. It can be understood that when the angular velocity remains unchanged, the larger the outer diameter, the larger the linear velocity. Since the linear velocity during cold start printing is smaller than that during hot start printing, the speed at which the paper passes through the fixing unit is actually slower. For example, in a certain cold start printing, the running speed of the paper on the paper path is A, and the speed at which the paper passes through the fixing unit is B, where B < A. It can be understood that since the front part of the paper passes through the fixing unit at a slower speed, while the speed of the rear part of the paper on the paper path is faster than the speed at which the paper passes through the fixing unit. The front part of the paper passes through at a slower speed and the rear part passes through at a faster speed. Therefore, the paper may assume a curved posture on the paper path. When the tail of the paper is pulled out from the transfer belt, the load that originally piled up at the paper tail on the transfer belt and blocked its movement will suddenly decrease, causing the transfer belt to accelerate.

[0061] When the external environmental temperature is high or when the image forming apparatus heats up due to being in a working state for a long time (i.e., hot start printing), the temperature of the fixing unit, as a heating component, will also rise. That is, the temperature of the pressure roller 109 in the fixing unit will rise. The pressure roller is made of rubber, and rubber expands when heated.

[0062] After the pressure roller 109 expands due to heat, its outer diameter will increase. When the angular velocity remains unchanged, the larger the outer diameter, the larger the linear velocity. Then, as the pressure roller rotates, the area where the paper wraps around the pressure roller will increase compared to that during cold start printing. The paper that was originally piled up on the transfer belt is pulled upward, and the paper is straightened, rather than assuming the curved state of the paper during cold start printing.

[0063] The inventor found that during low-temperature cold start, the fixing motor needs to rotate at a relatively fast speed to straighten the paper, reduce the load of the paper coming out of the transfer belt, so that the secondary transfer speed remains unchanged and the color registration is compliant. However, in previous designs, the rotation speed of the fixing motor was the same when the image forming apparatus printed any paper at a constant speed in any state. Even if the rotation speed of the fixing motor was changed, it was necessary to collect the outer diameter of the roller through a sensor and then adjust the rotation speed of the fixing motor according to the outer diameter of the roller.

[0064] An embodiment of the present invention provides a fixing motor control method, which is executed in Figure 1 the image forming apparatus shown, without using any sensor to measure the outer diameter of the roller and then adjust the speed of the fixing motor, saving costs. As Figure 2 shown, the method includes:

[0065] S100: Obtain a fixing target temperature, where the fixing target temperature is used to represent the temperature required for fixing and heating of the image forming apparatus;

[0066] In this embodiment, when the image forming device is printing, since the fixing component needs to perform a fixing operation in the fixing stage, the image forming device needs to control the fixing component to heat to the temperature required for fixing heating; the image forming device can control the fixing component to heat to the temperature required for fixing heating by obtaining the fixing target temperature.

[0067] In an optional embodiment, if Figure 3 As shown, step S100 of obtaining the fixing target temperature includes:

[0068] S110: Acquire current parameters of the image forming device, wherein the current parameters include at least one of the current number of printed pages, current environmental parameters, current fusing temperature, current printing paper type, and current printing mode;

[0069] In this embodiment, when the image forming device is printing, the current temperature required for fixing heating of the image forming device (i.e., the fixing target temperature) will vary depending on the current parameters of the image forming device, so the current parameters can be obtained before confirming the fixing target temperature. The current parameters include at least one of the current number of printed pages, current environmental parameters, current fixing temperature, current printing paper type, and current printing mode.

[0070] In an optional embodiment, when the image forming device is printing and generates heat due to being in working state for a long time, the temperature of the fixing component as a heating component will also rise, and different working time causes different degrees of temperature rise of the fixing component. The longer the working time, the greater the degree of temperature rise of the corresponding fixing component. At this time, the fixing target temperature that needs to be set can be relatively low. Conversely, the shorter the working time, the smaller the degree of temperature rise of the corresponding fixing component, and the fixing target temperature needs to be set relatively high. Among them, the working time can be expressed by the current number of printed pages of the image forming device, that is, the more pages are printed within a certain period of time, the higher the image forming device. The longer the device works, the shorter the working time of the image forming device is. Therefore, the current number of printed pages of the image forming device can be used to confirm the fixing target temperature. At the same time, the image forming device may print many pages continuously and then pause printing for a period of time. At this time, although the number of printed pages within a certain period of time is 0 or less, the fixing device is still in a relatively hot state. Therefore, the number of printed pages (working time) of the image forming device and the current fixing temperature can be combined to judge the state of the image forming device, and then confirm the fixing target temperature. Of course, the fixing target temperature can also be confirmed only by the current fixing temperature or only by the number of printed pages.

[0071] By determining the target fixing temperature according to at least one of the current parameters, the target fixing temperature can be a fixing temperature that is in line with the current situation and has a better fixing effect, thereby making the fixing effect more in line with user needs.

[0072] In an optional implementation, obtaining the current number of printed pages of the image forming device includes:

[0073] The number of pages printed by the image forming device within a preset time is obtained.

[0074] It is understandable that if the number of printed pages is to be obtained to determine whether it is cold machine printing or hot machine printing, it is not scientific to calculate the number of pages since the image forming device leaves the factory, resulting in an error in setting the fixing target temperature. At this time, a preset time can be set and the number of printed pages corresponding to the preset time can be obtained to solve the above problem. For example, the preset time is 10 minutes, and the number of printed pages within 10 minutes before the current time is obtained in real time. Among them, the number of printed pages N within 10 minutes is divided into three cases (i.e. corresponding to three print page number intervals), such as Figure 4 As shown, the first type is that the number of printed pages N is less than 20 pages, such as Figure 5 As shown, the second type is that the number of printed pages N ≥ 20 pages, and the number of printed pages N < 120 pages, such as Figure 6 As shown, the third type is that the number of printed pages N is ≥ 120 pages.

[0075] By setting a preset time and obtaining the number of printed pages corresponding to the preset time as the current number of printed pages, the value of the current number of printed pages can be more in line with the actual situation. The current number of printed pages will not be affected by the situation that a certain number of pages are printed, there is a period of time without printing, and then a certain number of pages are printed again, which will cause the setting error of the fixing target temperature.

[0076] In an optional implementation, if it is necessary to further determine the target fixing temperature based on the number of printed pages N (working time) and the current fixing temperature Ta, the current fixing temperature Ta (such as the temperature of the ceramic sheet of the fixing component detected by the thermistor) can be detected. The current fixing temperature Ta is specifically the fixing temperature at that moment, and the current fixing temperature Ta is combined with the number of printed pages N. The combined situations are divided into three situations, such as Figure 4 As shown, the first type is that the number of printed pages N is less than 20 pages and Ta is less than A℃. Figure 5 As shown, the second type is (20≤N<120 pages and Ta>B℃) or (N≤20 pages and Ta≥A℃), such as Figure 6 As shown, the third type is that the number of printed pages N ≥ 120 pages and Ta>B℃.

[0077] In an optional embodiment, when the image forming device is printing, the ambient temperature and ambient humidity can also affect the fixing temperature. When the ambient temperature is relatively high, the fixing target temperature is relatively low. On the contrary, when the ambient temperature is relatively low, the fixing target temperature is relatively high. Similarly, when the ambient humidity is high, the fixing target temperature is relatively high. On the contrary, when the ambient humidity is low, the fixing target temperature is relatively low. Therefore, the fixing target temperature can also be determined by the current ambient temperature T and the current ambient humidity RH of the image forming device. Correspondingly, Figure 4-Figure 6 As shown, the ambient temperature can also be divided into multiple ambient temperature intervals, such as T1≤T<T2, T2≤T<T3, etc. Similarly, the ambient humidity can also be divided into multiple ambient humidity intervals, such as RH1≤RH<RH2, RH2≤RH<RH3, etc.

[0078] In an optional embodiment, when the image forming device is printing, the type of paper currently being printed may be plain paper 1, plain paper 2, thin paper, thick paper 1, thick paper 2, thick paper 3, glossy label paper, matte label paper, envelope paper, card paper, film paper, photo paper, etc. Since the thickness and material of different types of paper may be different, their sensitivity and tolerance to temperature may also be different. For paper with high sensitivity and tolerance, the corresponding fixing target temperature is high, and for paper with low sensitivity and tolerance, the fixing target temperature is low; therefore, different types of paper may need to set different fixing target temperatures. Figure 4-Figure 6 As shown, the classification of the printed paper type P can be that each type of paper is classified into one type, or two or more types of paper are classified into one type, such as glossy label paper and matte label paper are set as one type, represented by the same letter. After the paper type P is classified into multiple types, they are recorded as P1, P2, ..., Pn in sequence.

[0079] In an optional embodiment, when the image forming device is printing, the type of paper currently being printed may be plain paper 1, plain paper 2, thin paper, thick paper 1, thick paper 2, thick paper 3, glossy label paper, matte label paper, envelope paper, card paper, film paper, photo paper, etc. Among them, the printing modes of plain paper 1, plain paper 2, and thin paper are divided into normal printing (normal speed printing) and silent printing (slow printing), and the remaining paper types are slow printing by default. The printing mode can also be set according to actual needs. For example, if the user inputs the command of the regular printing mode, even thick paper can use the regular printing mode. When other conditions are the same, the fixing target temperature during silent printing will be lower than the fixing target temperature during normal printing, so the fixing target temperature can also be set according to the printing mode, such as Figure 4-Figure 6 As shown, the printing mode M is divided into normal printing M1 and silent printing M2.

[0080] S120: Confirm the fixing target temperature according to the current parameters.

[0081] In this embodiment, when the image forming apparatus is printing, the current number of printed pages N, the current ambient temperature T, the current ambient humidity RH, the current printed paper type P, and the current printing mode M may all affect the fixing target temperature Tx. Figure 4-Figure 6 As shown, the fixing target temperature Tx can be confirmed according to the current number of printed pages N, the current ambient temperature T, the current ambient humidity RH, the current printed paper type P, and the current printing mode M. Correspondingly, the obtained fixing target temperatures Tx are recorded as Tx1, ..., Tx24n in sequence.

[0082] In an optional implementation, determining the fixing target temperature according to the current parameters includes:

[0083] The fixing target temperature is obtained in a preset temperature table according to the current parameters, wherein the temperature table has the fixing target temperature associated with the current parameters.

[0084] Specifically, the number of printed pages N, the ambient temperature T, the ambient humidity RH, the type of printed paper P, the printing mode M, and the fixing target temperature Tx associated with the above parameters can be prepared into a temperature table in advance, and the corresponding fixing target temperature Tx can be obtained by substituting the currently obtained number of printed pages N, the current ambient temperature T, the current ambient humidity RH, the currently printed paper type P, and the current printing mode M into the pre-prepared temperature table; for the pre-prepared temperature table, multiple printing page number intervals, multiple ambient temperature intervals, multiple ambient humidity intervals, multiple printed paper types, and two printing modes can be pre-arranged and combined to form multiple situations, and a fixing target temperature Tx is set for each situation, such as Figure 4-Figure 6As shown. When the current number of printed pages N, the current ambient temperature T, the current ambient humidity RH, the current printed paper type P, and the current printing mode M are obtained, they are substituted into the corresponding multiple printing page number intervals, multiple ambient temperature intervals, multiple ambient humidity intervals, multiple printed paper types, and two printing modes, and a printing page number interval that meets the requirements, an ambient temperature interval that meets the requirements, an ambient humidity interval that meets the requirements, a printed paper type that meets the requirements, and a printing mode that meets the requirements are confirmed. Finally, a unique fixing target temperature Tx is confirmed through a printing page number interval that meets the requirements, an ambient temperature interval that meets the requirements, an ambient humidity interval that meets the requirements, a printed paper type that meets the requirements, and a printing mode that meets the requirements. In addition, for pre-arranging and combining multiple printing page number intervals, multiple ambient temperature intervals, multiple ambient humidity intervals, multiple printed paper types, and two printing modes to form multiple situations, and setting a fixing target temperature for each situation, one or two of them can also be deleted according to needs, such as deleting multiple ambient humidity intervals, and arranging and combining the remaining situations to form multiple situations.

[0085] Exemplarily, taking the current ambient temperature T and the current number of printed pages N as an example, when the current ambient temperature T is low and the current number of printed pages N is small, that is, when the pressure roller 109 is cold and shrunk, in order to fix the toner on the paper, the fixing target temperature Tx of the fixing heating will be higher; under the opposite condition (that is, the current ambient temperature T is high and the current number of printed pages N is large), the fixing target temperature Tx of the fixing heating will be lower, that is, the fixing target temperature Tx will become lower as the current ambient temperature T becomes higher, and the fixing target temperature Tx will become lower as the current number of printed pages N becomes more. In addition, the current ambient humidity RH will also affect the fixing target temperature Tx, and the fixing target temperature Tx will become higher as the current ambient humidity RH becomes higher, and vice versa, it will become lower as the current ambient humidity RH becomes lower. The type of paper P currently printed will also affect the fixing target temperature Tx, and the fixing target temperature Tx will vary with the type of paper P currently printed. The current printing mode will also affect the fixing target temperature Tx. The fixing target temperature Tx during silent printing will be lower than the fixing target temperature Tx during normal printing.

[0086] S200: confirming the fixing motor speed according to the fixing target temperature to control the fixing motor rotation.

[0087] In this embodiment, if Figure 4-Figure 6As shown, the fixing motor speed V is confirmed by the fixing target temperature Tx to control the rotation of the fixing motor, and the obtained fixing motor speeds V are recorded as V1, ..., V24n in sequence; specifically, when the fixing target temperature Tx is high (cold machine printing at this time), the fixing motor speed V when printing this page of paper is increased; when the fixing target temperature Tx is low (hot machine printing at this time), the fixing motor speed V when printing this page of paper is slowed down, which can improve poor color registration.

[0088] In an optional implementation, determining the fusing motor speed according to the fusing target temperature includes:

[0089] The fixing motor speed is acquired in a preset control table according to the fixing target temperature, wherein the control table has the fixing motor speed associated with the fixing target temperature.

[0090] Specifically, the fixing target temperature Tx and the fixing motor speed V associated therewith may be prepared into a control table, such as: Figure 4-Figure 6 As shown, by substituting the acquired fixing target temperature Tx into a control table prepared in advance, the corresponding fixing motor speed V is acquired.

[0091] The fixing motor control method of the present embodiment confirms the fixing motor speed by obtaining the fixing target temperature, and does not need to use any sensor to measure the outer diameter of the roller and then adjust the fixing motor speed, thus saving costs. At the same time, the fixing motor speed is set directly according to the fixing target temperature, which has certain timeliness advantages and can avoid adjusting the fixing motor speed after poor color registration has occurred.
