[0036] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0038] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "said" 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.

[0039] It should be understood that the term " / and / " used herein is only a description of the associated 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 simultaneously, and b exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0040] The heat dissipation control method of the embodiment of the present application is applied to an image forming apparatus. The image forming apparatus is used to perform image forming operations, such as generating, printing, receiving and sending image data, and examples of the image forming apparatus include printers, scanners, copiers, fax machines, and multifunctional peripherals (MFPs, Multi-Functional Peripherals) that perform the above functions in a single device.

[0041] Such as Figure 1As shown, as an example of an image forming apparatus, the image forming apparatus includes a photosensitive drum 101Y-K, a charging roller 102Y-K, a developing roller 103Y-K, a toner cartridge 104Y-K, a transfer belt 105, a secondary transfer roller 106, a paper feed cassette 107, a manual paper feed tray 108, a paper feed roller 109, a conveyance roller 110, a paper detection sensor 120, a laser scanning unit (LSU, Laser Scanning Unit) 111, a heating roller 112, a pressure roller 113, a discharge roller 114, and a discharge paper tray 115, etc. Generally, the processing cartridge Y-K includes a photosensitive drum 101Y-K, a charging roller 102Y-K, a developing roller 103Y-K, and a toner cartridge 104Y-K for containing toner, respectively.

[0042] The LSU 111 is in the form of a single LSU and includes four optical paths. Four charging rollers 102Y-K are used to charge the surfaces of the four photosensitive drums 101Y-K respectively. The four optical paths of the LSU 111 emit laser beams respectively to form an electrostatic latent image on the surfaces of the photosensitive drums 101Y-K. Four developing rollers 103Y-K are used to develop and form a toner image of one color on the surfaces of the photosensitive drums 101Y-K respectively. The image forming apparatus adopts a secondary transfer method, that is, the four photosensitive drums 101Y-K transfer the toner images to the transfer belt 105 in sequence, and then the color toner image formed on the transfer belt 105 is secondarily transferred to the paper by the secondary transfer roller 106. The paper feed cassette 107 is used to store paper, and the paper feed roller 109 is used to convey the stored paper to the conveyance path, that is, the paper path channel. The conveyance roller 110 is used to convey the paper to the secondary transfer roller 106.

[0043] The secondary transfer roller 106 conveys the imaged paper to the clamping area of the heating roller 112 and the pressure roller 113. The heating roller 112 and the pressure roller 113 are used to fix the toner image on the paper. The heating roller 112 can adopt a ceramic heating method. The heating roller 112 and the pressure roller 113 convey the fixed paper to the discharge roller 114, and the discharge roller 114 discharges the paper to the discharge paper tray 115 and stacks it up.

[0044] Among them, the laser scanning unit 111 obtains an optical analog image signal of the original document / source file through the exposure of the optical print head. The laser scanning unit 111 includes an LSU temperature sensor (not shown in the figure), which is usually located inside the laser scanning unit 111. The paper detection sensor 120 is used to detect whether there is paper in the paper path channel at its location.

[0045] The paper supply cassette 107 is provided with a paper outlet. The paper feed roller 109 is specifically used to feed the paper contained in the paper supply cassette 107 from the paper outlet into the paper path channel for transfer requirements. The image forming apparatus further includes a driving mechanism (not shown in the figure) for driving the paper feed roller 109 to work. The driving mechanism is a driving motor for driving the paper feed roller 109 to move to achieve the paper feeding operation. The driving mechanism 181 is electrically connected to the controller (not shown in the figure) of the image forming apparatus to enable the controller to control the operation of the driving mechanism. The controller is electrically connected to the paper detection sensor 120, and the paper detection sensor sends the detection result information of whether there is paper on the paper path channel to the controller.

[0046] The image forming apparatus further includes an operation panel (not shown in the figure), an ITU cleaner 130, and an ambient temperature sensor 140. The operation panel includes an operation part (not shown in the figure) composed of various keys and a touch panel type display part (not shown in the figure). The ITU cleaner 130 is usually located near the imaging transfer unit, directly contacts the transfer belt, and cleans the residual toner through electrostatic adsorption or physical contact such as a cleaning blade or a cleaning brush, etc. The ambient temperature sensor 140 is used to monitor the ambient temperature inside the apparatus, usually near the main board inside the apparatus, near the paper feeding unit, etc., and the specific position depends on the design of the apparatus.

[0047] It can be understood that the above-listed image forming apparatuses are only examples. The component composition and component settings of the image forming apparatus can be adjusted according to the actual situation without affecting the improvement idea of the present invention.

[0048] With the continuous operation of the image forming apparatus or the influence of the ambient temperature, the temperature of the ITU cleaner will rise. When it reaches a certain temperature, the toner state inside the ITU cleaner will change, and caking is likely to occur at the powder inlet and on the inner wall, sticking to the inner wall of the waste toner conveying pipe of the ITU cleaner. Seriously, the powder inlet will be blocked, resulting in the ITU cleaner losing its cleaning ability and being unable to print normal images.

[0049] The existing heat dissipation method usually requires adding a temperature sensor at the ITU cleaner to detect its temperature in real time and cooling it through a fan. This method needs to change the original structure inside the image forming apparatus, has a high cost, and the heat dissipation method has low efficiency.

[0050] In view of the above problems, the embodiment of the present application provides a heat dissipation control method. The temperature of the ITU cleaner can be directly determined through the original temperature detection device of the image forming apparatus and the temperature correlation relationship between each module and the ITU cleaner, without adding a new temperature detection device. Moreover, by combining the two methods of fan cooling and paper feeding cooling, the cooling efficiency can be improved, ensuring the normal operation of the ITU cleaner.

[0051] Figure 2Schematic flowchart of a heat dissipation control method provided by an embodiment of the present application. As Figure 2 shown, the method may include:

[0052] Step 201, obtaining the temperature in the image forming apparatus based on a temperature detection device of at least one module in the image forming apparatus.

[0053] In one embodiment, the module temperature of the corresponding module is obtained based on a temperature detection device of at least one module in the image forming apparatus. In another embodiment, the ambient temperature in the image forming apparatus is obtained based on a temperature detection device at the position of at least one module in the image forming apparatus.

[0054] Specifically, the temperature detection device is a device for detecting the internal temperature of the image forming apparatus. The temperature detection device may be a sensor or a device that indirectly or directly detects temperature by various methods such as semiconductor characteristics or optical characteristics.

[0055] Some modules in the image forming apparatus are configured with temperature detection devices for detecting the corresponding temperature. For example, an LSU temperature sensor is configured in the laser scanning unit to detect and control the temperature inside the laser scanning unit, ensure its stable and accurate operation, prevent the laser scanning unit from being damaged due to too high or too low temperature, and extend the service life of the apparatus. Another example is that a temperature detection device is also configured in the heating roller to detect the temperature of the heating roller, ensure the imaging quality, and prevent the heating roller from being damaged due to overheating.

[0056] Specifically, in one embodiment, the temperature of the laser scanning unit is detected based on the LSU temperature sensor in the image forming apparatus. In another embodiment, the temperature of the fixing heating unit is detected based on the heating roller temperature sensor in the image forming apparatus. In yet another embodiment, the ambient temperature in the image forming apparatus is detected based on the ambient temperature sensor in the image forming apparatus, where the ambient temperature sensor is located inside the image forming apparatus and belongs to a certain module in the image forming apparatus.

[0057] The module in the embodiment of the present application may refer to any module in the image forming apparatus configured with a module temperature detection device, such as a laser scanning unit, a heating roller, or other eligible modules.

[0058] Step 202, when the temperature in the image forming apparatus reaches the temperature threshold, the image forming apparatus performs a heat dissipation control process.

[0059] Wherein, the temperature threshold is related to the correlation between the temperature of the corresponding module and the temperature of the heat dissipation object.

[0060] Specifically, the object to be cooled is an object in an abnormal state such as failure due to excessive self - temperature in an image forming apparatus, for example, an ITU cleaner that has agglomerated inside due to high temperature. In the embodiments of the present application, the ITU cleaner is taken as an example for illustration.

[0061] In one embodiment, based on the positions of the modules of the image forming apparatus and the working influence, there is a certain correlation relationship between the temperatures of different modules. Under the condition that the temperature detection devices of each module detect the module temperature of the corresponding module in real - time, based on the temperature correlation relationship between one or more module temperatures and the temperature of the ITU cleaner, it is possible to more accurately determine whether the current temperature of the ITU cleaner is too high. If the temperature is too high, heat dissipation treatment needs to be performed on the ITU cleaner. Similarly, in another embodiment, under the condition that the temperature detection devices of each module detect the temperature in the image forming apparatus in real - time, based on the detected module temperature or based on the correlation relationship between the detected ambient temperature and the temperature of the ITU cleaner, it is possible to more accurately determine whether the current temperature of the ITU cleaner is too high. If it is too high, heat dissipation treatment needs to be performed on the ITU cleaner.

[0062] Generally, there is a positive temperature correlation relationship between the ITU cleaner and other modules, that is, when the temperature of other modules increases, the temperature of the ITU cleaner will also increase accordingly. Conversely, when the temperature of other modules decreases, the temperature of the ITU cleaner will also decrease accordingly. To ensure that the ITU cleaner does not fail due to overheating, the temperature of the ITU cleaner should not exceed a certain temperature threshold. Based on the temperature correlation relationship between the ITU cleaner and other modules, the corresponding temperature thresholds can be obtained for other modules. Exemplarily, the temperature thresholds of other modules can be set in advance according to the corresponding temperature correlation relationship, or can be obtained by querying a table or formula corresponding to the temperature correlation relationship. When the module temperature of one or more modules reaches the corresponding temperature threshold, it can be determined that the temperature of the ITU cleaner has also reached the corresponding temperature threshold.

[0063] For example, there is a certain temperature correlation relationship between the temperature of the laser scanning unit and the temperature of the ITU cleaner. Assume that when the temperature of the laser scanning unit is 35°C, the temperature of the ITU cleaner is 40°C. If the safe temperature of the ITU cleaner is not more than 40°C, its temperature threshold can be set to 40°C. Correspondingly, the temperature threshold of the laser scanning unit can be set to 35°C. When it is detected that the temperature of the laser scanning unit gradually rises to 35°C, it can be determined that the temperature of the ITU cleaner has reached 40°C, and the image forming apparatus performs heat dissipation control processing.

[0064] In the embodiments of the present application, the corresponding temperature is obtained through the existing temperature detection device of any module in the image forming apparatus, and then the temperature of the heat dissipation object is predicted based on the correlation relationship of the temperature, so that the temperature of the heat dissipation object can be detected without adding a new temperature detection device. When the temperature of the heat dissipation object is relatively high, heat dissipation control processing is performed to prevent the heat dissipation object from being damaged by heat.

[0065] In an alternative embodiment, the temperature threshold includes: a first temperature threshold and / or a second temperature threshold. When the temperature reaches the temperature threshold, the image forming apparatus performs heat dissipation control processing, including:

[0066] When the temperature is greater than or equal to the first temperature threshold, the image forming apparatus performs heat dissipation processing; when the temperature is less than or equal to the second temperature threshold, the image forming apparatus ends the heat dissipation processing.

[0067] Specifically, when the ITU cleaner drops to a certain temperature and can work normally, the heat dissipation processing can be ended. Therefore, a lower limit value of the temperature can be set. When it is detected that the temperature is greater than or equal to the first temperature threshold, that is, the upper limit value of the temperature, the image forming apparatus can perform heat dissipation processing on the ITU cleaner. During the heat dissipation processing, when it is detected that the temperature is less than or equal to the second temperature threshold, that is, the lower limit value of the temperature, the image forming apparatus ends the heat dissipation processing and restores to the original state.

[0068] Exemplarily, when the temperature reaches the temperature threshold, the heat dissipation control processing performed by the image forming apparatus may only include any one or a combination of the following two: when the temperature is greater than or equal to the first temperature threshold, the image forming apparatus performs heat dissipation processing, and when the temperature is less than or equal to the second temperature threshold, the image forming apparatus ends the heat dissipation processing.

[0069] In the embodiments of the present application, by setting the first temperature threshold and / or the second temperature threshold, both the situation of performing heat dissipation processing and ending heat dissipation processing are considered, avoiding performing heat dissipation processing when the temperature of the ITU cleaner is too low, which may cause the print quality to deteriorate and waste resources, and effectively improving the processing efficiency.

[0070] In an alternative embodiment, when the temperature is greater than or equal to the first temperature threshold, the heat dissipation processing performed by the image forming apparatus includes:

[0071] When the temperature is greater than or equal to the first temperature threshold and the ambient temperature in the image forming apparatus reaches the third temperature threshold, the image forming apparatus performs heat dissipation processing.

[0072] Wherein, the ambient temperature is the temperature inside the image forming apparatus and is used to represent the overall temperature of the image forming apparatus.

[0073] Specifically, the temperature of the module is the temperature of the module local to the image forming apparatus. To more accurately predict whether the temperature of the ITU cleaner has reached the temperature at which heat dissipation processing needs to be performed, it is also possible to determine whether heat dissipation processing needs to be performed by combining the temperature of the module in the image forming apparatus and the ambient temperature. When the temperature is greater than or equal to the first temperature threshold and the ambient temperature in the image forming apparatus reaches the third temperature threshold, i.e., the upper limit value of the ambient temperature, the image forming apparatus performs heat dissipation processing to dissipate heat from the ITU cleaner. Among them, an existing ambient temperature sensor in the image forming apparatus or other temperature detection devices for detecting the internal temperature of the image forming apparatus can be used.

[0074] Exemplarily, based on the correlation between the temperature of the ITU cleaner, the temperatures of other modules, and the ambient temperature, the image forming apparatus can obtain a comprehensive temperature through weighted calculation. This comprehensive temperature can be used to characterize the temperature of the ITU cleaner. When the comprehensive temperature exceeds the corresponding temperature threshold, the image forming apparatus can perform a temperature reduction process. Optionally, a larger weight can be set for the temperature of the module that is strongly associated with the ITU cleaner to improve the accuracy of the comprehensive temperature.

[0075] In the embodiments of the present application, by combining the ambient temperature to determine whether to perform heat dissipation processing, it is possible to avoid situations where incorrect determinations are caused by factors such as malfunctions of the temperature detection device for the module temperature and only the module heating up while the ITU cleaner does not heat up synchronously. By comprehensively determining based on the ambient temperature and the module temperature, the determination accuracy can be improved.

[0076] In an alternative embodiment, the heat dissipation control process includes:

[0077] Controlling the operation of the fan device in the image forming apparatus to achieve heat dissipation processing through the fan device; and / or, controlling the operation of the paper feeding device in the image forming apparatus to achieve heat dissipation processing through paper feeding.

[0078] Among them, when the paper feeding device is operating, the fixing device in the image device does not perform heating processing. The fixing module mainly includes a heating roller and a pressure roller for performing toner fixing operations.

[0079] Specifically, a fan device is configured inside the image forming apparatus. After the fan device is started, it can reduce the temperatures of the various modules of the image forming apparatus. At the same time, the image forming apparatus can directly remove the heat of each part of the paper path channel, such as the transfer belt, transfer roller, heating roller, and pressure roller, by means of transmitting paper through the paper feeding device, thereby reducing the temperatures of the various modules of the image forming apparatus. It can be understood that by continuously transmitting printing paper, the heat of the transfer belt, etc. will be transferred to the printing paper to quickly reduce the temperatures of the modules including the ITU cleaner.

[0080] In the embodiments of the present application, by using the original devices of the image forming apparatus, heat dissipation processing is achieved through the fan device and / or the paper feeding device. The fan device and the paper feeding device operate jointly or separately to be applicable to various situations. At the same time, the ITU cleaner is effectively cooled, solving the problem of heat-induced failure of the ITU cleaner.

[0081] In an alternative embodiment, the heat dissipation control processing includes:

[0082] When the image forming apparatus is in an operating state, the execution of the current job task is paused.

[0083] Herein, the operating state means that the image forming apparatus is executing a job task related to image formation, such as printing, copying, scanning, etc.

[0084] Specifically, when the image forming apparatus pauses the execution of the current job task, some modules stop generating heat due to the stopped job and at the same time dissipate heat to the environment, thereby cooling down the image forming apparatus. It can be understood that when the image forming apparatus is in an operating state, by pausing the execution of the current job task, modules including the ITU cleaner will continuously dissipate heat to quickly reduce the temperature of the ITU cleaner.

[0085] In the embodiments of the present application, by pausing the execution of the current job task, heat dissipation is effectively performed without using other devices, saving resources at the same time.

[0086] Exemplarily, for different situations, the image forming apparatus can perform different heat dissipation control processing. Among the heat dissipation processing achieved through the fan device, the heat dissipation processing achieved through paper feeding, and the pausing of the execution of the current job task, any one, a combination of two, or a combination of three can be executed, and the execution order can be selected according to actual needs. The embodiments of the present application do not limit this.

[0087] In an alternative embodiment, the heat dissipation control processing further includes: heat dissipation control processing in the first mode and heat dissipation control processing in the second mode;

[0088] The heat dissipation control processing in the first mode is executed when the image forming apparatus is in a non-operating state and includes: the fan device runs at a predetermined speed;

[0089] The heat dissipation control processing in the second mode is executed when the image forming apparatus is in an operating state and includes: pausing the execution of the current job task, controlling the fan device to run at a predetermined speed, and controlling the paper feeding device to transport paper. When the paper feeding device transports paper, the fixing device is controlled not to perform heating processing.

[0090] Herein, the non-operating state means that the image forming apparatus is not executing a job task related to image formation, such as the standby state and the sleep state, etc.

[0091] Specifically, for different states, the image forming apparatus performs different heat dissipation control processes. When the image forming apparatus is in a non-operating state, the image forming apparatus can perform heat dissipation only through the fan device. Specifically, the image forming apparatus controls the fan device to operate at a preset speed to quickly reduce the temperature of the ITU cleaner. When the image forming apparatus is in an operating state, it first pauses the execution of the current job task, then controls the fan device to operate at a preset speed, and at the same time controls the paper feeding device to transport paper. Among them, during the process of the paper feeding device transporting the printed paper, the fixing module of the image forming apparatus does not perform heating to facilitate faster heat dissipation.

[0092] Optionally, after the image forming apparatus performs the heat dissipation control process, it further includes: when the image forming apparatus is in an operating state, reducing the speed of executing the job task.

[0093] Specifically, after the heat dissipation control process ends, the image forming apparatus can continue to execute the previous job task. Optionally, in order to prevent the temperature from rising again in a short time, the image forming apparatus can reduce the processing speed of this job task. For example, if the default normal speed printing is used, after the heat dissipation control process, the image forming apparatus can use slow speed printing to process this job task. After this job task is processed, subsequent job tasks can resume normal speed printing.

[0094] In the embodiment of the present application, after the heat dissipation control process, reducing the speed of executing the job task can avoid the temperature rising again in a short time to reach the corresponding temperature threshold. At the same time, the slow printing speed and the corresponding temperature threshold are set in coordination, which can increase the working time of the image forming apparatus in the operating state, reduce the time of pausing work due to heat dissipation processing, ensure the normal operation of the image forming apparatus, and improve the user experience.

[0095] The temperature detection device of the following module takes the LSU sensor of the laser scanning unit, and the heat dissipation object takes the ITU cleaner as an example to illustrate the method of the embodiment of the present application.

[0096] The temperature relationship between the LSU temperature and the ITU cleaner temperature may include but is not limited to the following various situations:

[0097] (1) When the LSU temperature is 30 °C, the temperature of the ITU cleaner is 35 °C. For every 1 °C increase in the LSU temperature, the temperature of the ITU cleaner also rises by 1 °C.

[0098] (2) When the LSU temperature is 30 °C, the temperature of the ITU cleaner is 35 °C. For every 1 °C increase in the LSU temperature, the temperature of the ITU cleaner rises by 0.8 °C. When the LSU temperature reaches 35 °C, the ITU cleaner temperature is 39 °C.

[0099] (3) When the LSU temperature is 30°C, the temperature of the ITU cleaner is 35°C. Within 100 pages of printing, for every 1°C increase in the LSU temperature, the temperature of the ITU cleaner rises by 0.8°C. Within 100 - 500 pages of printing, for every 1°C increase in the LSU temperature, the temperature of the ITU cleaner rises by 1.2°C. When the LSU temperature reaches 35°C and the number of printed pages is 80, the temperature of the ITU cleaner is 39°C. The above temperature correlation is only an exemplary description. In actual scenarios, there may be other correlation relationships between the LSU temperature and the temperature of the ITU cleaner.

[0100] When the image forming device is in the working state, the heat dissipation control processing flow can refer to Figure 3 , and specifically may include:

[0101] Step 301, process the current job task at normal speed.

[0102] Step 302, determine whether the ambient temperature is greater than or equal to A°C and whether the LSU temperature is greater than or equal to B1°C. If so, enter Step 303; otherwise, return to Step 301.

[0103] During this process, the ambient temperature sensor continuously collects the ambient temperature, and the LSU sensor continuously collects the LSU temperature, and respectively determines whether they are both greater than or equal to the corresponding temperature thresholds. For example, referring to the above temperature correlation, the third temperature threshold corresponding to the ambient temperature can be set to 32°C, and the first temperature threshold and the second temperature threshold corresponding to the LSU temperature can be set to 45°C and 43°C respectively.

[0104] Step 303, suspend the execution of the job task.

[0105] When the ambient temperature is greater than or equal to 32°C and the LSU temperature is greater than or equal to 45°C, the image forming device suspends the execution of the current job task.

[0106] Step 304, the fan device runs, and the paper feeding device feeds C pages of paper.

[0107] Heat dissipation treatment is performed on the ITU cleaner and other modules through the fan device and the paper feeding device. C can be set to 6, 8, or other reasonable values. During this process, the fusing module does not perform heating, and modules such as the charging roller can also suspend working.

[0108] Step 305, determine whether the LSU temperature is less than or equal to B2°C. If so, enter Step 306; otherwise, return to Step 304.

[0109] If the LSU temperature is still relatively high, return to Step 304 to continue the heat dissipation treatment. If the LSU temperature is already less than or equal to 43°C, then end the cooling process.

[0110] Step 306, slowly process the current job task.

[0111] To prevent the device temperature from rising again, the image forming device slowly processes the current job task. The next job task can resume normal speed processing and re-enter the heat dissipation control processing flow for temperature judgment and other operations.

[0112] When the image forming device is in a non-operating state, the heat dissipation control processing flow can refer to Figure 4 , specifically including:

[0113] Step 401, detect the LSU temperature and the ambient temperature in real time.

[0114] When in the non-operating state, the image forming device collects the LSU temperature and the ambient temperature in real time.

[0115] Step 402, determine whether the ambient temperature is greater than or equal to A °C and whether the LSU temperature is greater than or equal to B1 °C. If so, enter Step 403; otherwise, return to Step 401.

[0116] Step 403, the fan device runs.

[0117] When in the non-operating state, the image forming device dissipates heat only through the fan device. Optionally, considering the impact of the noise of the fan device on the user in the non-operating state, the fan device can also run at a low speed.

[0118] Step 404, determine whether the LSU temperature is less than or equal to B2 °C. If so, enter Step 405; otherwise, return to Step 403.

[0119] Step 405, end the heat dissipation control processing flow.

[0120] In the embodiments of the present application, by comprehensively determining whether heat dissipation control processing should be performed based on the ambient temperature and the module temperature, it can be ensured that the ITU cleaner will not be damaged due to excessive temperature, and at the same time, no new hardware costs will be added. By performing different heat dissipation control processing in different states, the three methods of the fan device running, the paper feeding device running, and pausing the job cooperate with each other, effectively improving the heat dissipation efficiency, improving the applicability of heat dissipation control, shortening the user waiting time, and improving the user experience.

[0121] In an alternative embodiment, the above heat dissipation control method can also be used to cool other modules, and the control strategy, the running speed of the fan device, etc. can be adjusted according to the actual situation. For example, when the control chip of the image forming device processes job tasks for a long time, there is a risk of system crash due to excessive temperature rise of the control chip. To solve this problem, the image forming device can detect the chip temperature in real time. When the chip temperature is higher than a certain threshold, the fan device is turned on to cool the chip to avoid the risk of system crash.

[0122] Specifically, for different working states, the fan device can adopt different operating speeds to cool the control chip. When the image forming device is in a non-working state and the chip temperature exceeds the upper temperature limit value, the control fan device runs at a low speed until the chip temperature drops to the lower temperature limit value and then stops running. When the image forming device has just completed the current job task and the chip temperature exceeds the upper temperature limit value, the control fan device runs at a high speed. Considering that the noise of the fan device may affect the user experience, after the fan device runs at a high speed for a first duration such as 5 minutes or other reasonable durations, it can be switched to run at a low speed. During this process, when it is detected that the chip temperature drops to the lower temperature limit value, the control fan device is controlled to stop running. When the image forming device is processing a job task and the chip temperature exceeds the upper temperature limit value, the control fan device continuously runs at a high speed until the chip temperature drops to the lower temperature limit value.

[0123] Through the above control strategy, when the temperature of the control chip in the image forming device is too high, the image forming device can take into account factors such as noise pollution, heat dissipation efficiency, and heat dissipation duration, and perform heat dissipation treatment on the control chip to avoid its thermal damage and extend the device life.
