Description

Technical Field

[0001] This disclosure relates to the field of temperature control, and more specifically, to a fixing temperature control method, apparatus, electronic device, storage medium, and product. Background Technology

[0002] The fusing process in a printer uses heat and pressure to fix the toner image onto the paper. This process mainly involves the fuser using heated and pressurized rollers to melt the toner and penetrate it into the paper, thus forming a permanent image. The fusing temperature is typically quite high.

[0003] In some scenarios, if a printer continuously performs printing jobs, it may accumulate a large amount of heat inside the device. When the heat buildup is too high, the internal temperature of the device will rise, which can easily cause the ambient temperature sensor to misjudge the actual ambient temperature. This will affect the accuracy of the fixing temperature strategy to some extent, and may lead to problems with poor fixing of the image. Summary of the Invention

[0020] To make the above-mentioned objects, features and advantages of this disclosure more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0021] To more clearly illustrate the technical solutions of the embodiments of this disclosure, the accompanying drawings used in the embodiments will be briefly described below. These drawings are incorporated in and constitute a part of this specification. They illustrate embodiments conforming to this disclosure and, together with the specification, serve to explain the technical solutions of this disclosure. It should be understood that the following drawings only show some embodiments of this disclosure and should not be considered as limiting the scope. Those skilled in the art can obtain other related drawings based on these drawings without creative effort.

[0022] Figure 1 A flowchart of a fixing temperature control method provided by an embodiment of this disclosure is shown; Figure 2 A flowchart of another fixing temperature control method provided by an embodiment of this disclosure is shown; Figure 3 A schematic diagram of a fixing temperature control device provided in an embodiment of this disclosure is shown; Figure 4 A schematic diagram of an electronic device provided in an embodiment of the present disclosure is shown. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In this document, the term "and / or" merely describes a relationship, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0026] The fusing process in a printer uses heat and pressure to fix the toner image onto the paper. During printing, the toner image transferred to the paper through the transfer and separation process is not yet fully integrated with the paper. At this stage, the toner image on the paper is easily erased, so a fusing unit is needed to solidify it and form the final print result. The fusing unit includes a heated roller and a pressure roller. The heated roller is heated by a heated fusing lamp mounted on it, which heats the printing media, melting the toner on the media. The heat from the heated roller then fixes the toner onto the printing media. The pressure roller uses spring pressure to press the printing media firmly against the heated roller, effectively fixing the toner image onto the paper.

[0027] In some scenarios, if a printer continuously performs printing jobs, it may accumulate a large amount of heat inside the device. When the heat buildup is too high, the internal temperature of the device will rise, which can easily cause the ambient temperature sensor to misjudge the actual ambient temperature. This will affect the accuracy of the fixing temperature strategy to some extent, and may lead to problems with poor fixing of the image.

[0028] The fixing temperature is typically above 150°C, sometimes reaching 230°C or higher. For example, when printing at low temperatures, where the actual ambient temperature is usually below 20°C, the fixing temperature should be 220°C; when printing at room temperature, where the actual ambient temperature is between 20°C and 30°C, the fixing temperature should be 200°C. When prolonged printing causes temperature buildup, the internal temperature of the printing equipment rises. For instance, the ambient temperature sensor might detect an actual ambient temperature of 31°C, deviating from the true ambient temperature. In this case, the fixing temperature might change to 180°C, potentially leading to poor fixing.

[0029] Based on the above research, this disclosure provides a fixing temperature control method, apparatus, electronic device, storage medium, and product. In the embodiments of this application, firstly, the real-time ambient temperature of the printing device is acquired; then, the operating status of the printing device and environmental change information of the environment in which the printing device is located are determined; next, based on the operating status and environmental change information, a new current ambient temperature of the printing device is determined from the real-time ambient temperature and a first ambient temperature; wherein, the first ambient temperature is the current ambient temperature previously determined for the printing device; finally, the fixing strategy of the printing device is determined based on the new current ambient temperature.

[0030] In the above embodiments, by using the operating status of the printing device and the environmental change information of the environment in which the printing device is located, the current ambient temperature of the printing device is determined from the real-time ambient temperature and the first ambient temperature. It is possible to analyze the reasons that may cause changes in the detected value of the ambient temperature of the printing device from changes in the external environment of the printing device and the internal heat accumulation of the printing device, so as to determine a more accurate current ambient temperature for the printing device based on the reasons, thereby improving the accuracy of the fixing strategy and alleviating the technical problem of incorrect fixing strategy caused by misjudgment of the true ambient temperature due to overheating caused by heat accumulation inside the printing device.

[0031] To facilitate understanding of this embodiment, a fixing temperature control method disclosed in this disclosure will first be described in detail. The fixing temperature control method provided in this disclosure is generally executed by an electronic device with a certain computing capability. In some possible implementations, the fixing temperature control method can be implemented by a processor calling computer-readable instructions stored in memory.

[0032] See Figure 1 The diagram shows a flowchart of a fixing temperature control method provided in an embodiment of this disclosure. The method includes steps S101 to S104, wherein: S101: Obtain the real-time ambient temperature of the printing device.

[0033] The system obtains the real-time ambient temperature of the printing equipment through an environmental temperature sensor pre-installed on the equipment. For example, after the printing equipment is turned on, the ambient temperature sensor begins to collect the temperature of the environment in which the printing equipment is located.

[0034] S102: Determine the operating status of the printing equipment and information on environmental changes in the environment in which the printing equipment is located.

[0035] The operating status of the printing equipment can be obtained from its printing data, such as the total number of pages printed or the total printing time. Environmental change information indicates whether the environment in which the printing equipment is located has undergone significant changes. Here, a significant change in the environment refers to a rise or fall in the ambient temperature within a certain temperature range, such as 15-20 degrees Celsius. This can be determined through external environmental detection devices or by using the ambient temperature sensor on the printing equipment in conjunction with a pre-set environmental change recognition mechanism.

[0036] In the embodiments of this application, the operating states of the printing device include a hot state as a first state and a cold state as a second state.

[0037] The "hot machine status" indicates that the printing equipment has reached the specified operating temperature, while the "cold machine status" indicates that the printing equipment has not reached the specified operating temperature.

[0038] When the printer is in a warm-up state, the heat accumulated inside the printer may affect the readings of the ambient temperature sensor (i.e., the real-time ambient temperature). For example, if the external environment of the printer does not change significantly, the increase in the temperature readings collected by the ambient temperature sensor is likely due to the heat accumulated inside the printer. When the printer is in a cold-up state, the heat inside the printer may not affect the readings of the ambient temperature sensor, or its impact on the readings may be minimal. For example, if the external environment of the printer does not change significantly, the heat inside the printer may not cause the temperature collected by the ambient temperature sensor to rise, or the increase in the temperature collected by the ambient temperature sensor may be less than a preset temperature threshold.

[0039] S103: Based on the operating status and environmental change information, determine the new current ambient temperature of the printing device from the real-time ambient temperature and the first ambient temperature; wherein, the first ambient temperature is the current ambient temperature previously determined for the printing device.

[0040] The current ambient temperature represents the actual ambient temperature of the environment in which the printing equipment is currently located. The current ambient temperature is not fixed but dynamically updated based on factors such as the printing equipment's operating status, environmental changes, and the collected real-time ambient temperature. The new current ambient temperature is the value determined each time the fixing temperature control method is executed, based on the real-time ambient temperature, the first ambient temperature, the operating status, and environmental change information. This temperature value replaces the previous current ambient temperature. The new current ambient temperature can be the same as the previous current ambient temperature (i.e., the previous current ambient temperature remains unchanged) or different from the previous current ambient temperature (i.e., the previous current ambient temperature is updated). The first ambient temperature represents the previously determined actual ambient temperature that approximates the current environment (i.e., the original current ambient temperature).

[0041] S104: Determine the fixing strategy of the printing equipment based on the new current ambient temperature.

[0042] When high levels of heat accumulate inside the printing equipment, it will affect the readings of the ambient temperature sensor. For example, the sensor reading may become higher than the actual ambient temperature. In this case, the fixing temperature determined based on this reading may be inaccurate, thus affecting the fixing effect.

[0043] Therefore, in this embodiment, the reasons that may cause changes in the detected value of the printing device's ambient temperature can be analyzed from changes in the external environment of the printing device and internal heat storage of the printing device. For example, if it is determined based on environmental change information that the environment in which the printing device is located has changed significantly, then the reason affecting the detected value of the ambient temperature sensor may be the "external environment"; or, if it is determined based on environmental change information that the environment in which the printing device is located has not changed significantly, but the operating status indicates that the printing device is in a hot-running state, then the reason affecting the detected value of the ambient temperature sensor may be "internal heat storage of the printing device".

[0044] At this point, by determining the current ambient temperature of the printing device from the real-time ambient temperature and the first ambient temperature based on the above reasons, a more accurate ambient temperature can be obtained, thereby improving the accuracy of the fixing strategy and alleviating the technical problem of incorrect fixing strategy caused by misjudgment of ambient temperature due to overheating caused by heat accumulation inside the printing device.

[0045] In this embodiment of the application, step S101, which involves obtaining the real-time ambient temperature of the printing device, includes: Multiple temperature values ​​of the environment where the printing device is located are collected at preset time intervals, and the average value of the multiple temperature values ​​is calculated to obtain the real-time ambient temperature.

[0046] After the printing equipment is powered on, the ambient temperature sensor collects multiple temperature values ​​of the environment in which the printing equipment is located at preset time intervals, calculates the average value of the collected multiple temperature values, and determines the calculated average value as the real-time ambient temperature.

[0047] After calculating the real-time ambient temperature, the operating status of the printing equipment and the environmental change information of the environment in which the printing equipment is located are determined. Then, based on the operating status and environmental change information, the new current ambient temperature of the printing equipment is determined from the real-time ambient temperature and the first ambient temperature. For example, the real-time ambient temperature is determined as the new current ambient temperature, or the first ambient temperature is determined as the new current ambient temperature.

[0048] After determining the current ambient temperature, the ambient temperature sensor continues to collect multiple temperature values ​​of the environment where the printing device is located at preset time intervals, and after calculating the average value of the multiple temperature values, repeats the above steps S102 to S104 until the printing device is turned off.

[0049] Here, users can set the duration of the preset time interval and the number of multiple temperature values ​​as needed.

[0050] In this embodiment, multiple ambient temperature sensors can be set at different locations inside the printing device, and each ambient temperature sensor is set to collect temperature data at a preset time interval. Then, the average value of the temperature values ​​collected by the multiple ambient temperature sensors is calculated to obtain the real-time ambient temperature.

[0051] The above processing method can more accurately collect the ambient temperature of the printing equipment's environment, providing a more accurate basis for judging environmental changes.

[0052] In this embodiment of the application, step S102, which determines the operating status of the printing device, specifically includes the following methods: Method 1: Count the total number of pages printed by the printing device within a preset time period, and determine the operating status based on the total number of pages printed; Method 2: Calculate the total printing time of the printing device within the preset time period, and determine the operating status based on the total printing time.

[0053] Specifically, if the total number of pages printed is greater than or equal to the preset number of pages, or the total printing time is greater than or equal to the preset time, the operating state is determined to be the first state; if the total number of pages printed is less than the preset number of pages, or the total printing time is less than the preset time, the operating state is determined to be the second state; the first state is used to indicate that the printing device has reached the specified operating temperature, and the second state is used to indicate that the printing device has not reached the specified operating temperature.

[0054] Here, the preset time period is a duration preceding the current moment, for example, X minutes preceding the current moment. The first state is the warm-up state described above, and the second state is the cold-up state described above.

[0055] In one optional method, the total number of pages printed (A) within X minutes prior to the current time is counted. If the total number of pages printed (A) is greater than or equal to a preset number of pages (B), the operating state is determined to be the first state (also known as the warm-up state); if the total number of pages printed (A) is less than the preset number of pages (B), the operating state is determined to be the second state (also known as the cold-up state). The inventors have discovered that within a preset time period, when the total number of pages printed by the printing device reaches the preset number, the printing device can usually reach the specified operating temperature. Therefore, the operating state of the printing device, whether it is the first state or the second state, can be determined by judging the total number of pages printed.

[0056] It should be noted that the specific values ​​of the total number of pages to be printed and the preset number of pages may be the same or different for different models of printing devices. You can flexibly set the specific values ​​of the total number of pages to be printed and the preset number of pages according to different models, so as to achieve the desired result. There is no specific limit to the values ​​of the total number of pages to be printed and the preset number of pages here.

[0057] Another alternative approach involves calculating the total printing time M of the printer within X minutes prior to the current moment. If the total printing time M is greater than or equal to a preset time N, the operating state is determined to be the first state (also known as the warm-up state); if the total printing time M is less than the preset time N, the operating state is determined to be the second state (also known as the cold-up state). The inventors discovered that within a preset time period, when the total printing time of the printer reaches the preset time, the printer typically reaches the specified operating temperature. Therefore, the operating state of the printer (first or second state) can be determined by judging the total printing time.

[0058] It should be noted that the specific values ​​of the total printing time and the preset printing time may be the same or different for different models of printing devices. The specific values ​​of the total printing time and the preset printing time can be flexibly set according to different models, based on what is feasible. There is no specific limitation on the values ​​of the total printing time and the preset printing time here.

[0059] Besides using total printing time and total number of pages printed as the basis for judging the operating status, other criteria can also be used to determine the operating status of the printing equipment. For example, the total number of motor revolutions of the printing equipment within a preset time period can be counted, and then the operating status of the printing equipment, whether it is in the first state or the second state, can be determined based on the total number of motor revolutions.

[0060] In the above embodiments, determining the operating status of the printing device by the total number of pages printed or the total printing time can more quickly and accurately determine whether the printing device is in a hot or cold state, thereby providing a more reasonable basis for determining the current ambient temperature.

[0061] In this embodiment of the application, step S102, which determines the environmental change information of the environment in which the printing device is located, specifically includes the following steps: Step S11: Obtain the device saturation temperature corresponding to the current ambient temperature; wherein, the device saturation temperature is used to indicate the highest temperature that the printing device can reach under the current ambient temperature; Step S12: Calculate the absolute value of the temperature difference between the equipment saturation temperature and the current ambient temperature to obtain the first temperature difference; Step S13: Calculate the absolute value of the temperature difference between the real-time ambient temperature and the current ambient temperature to obtain the second temperature difference; Step S14: Based on the comparison between the first temperature difference and the second temperature difference, determine the environmental change information of the environment in which the printing device is located.

[0062] Here, the current ambient temperature described in step S11 refers to the ambient temperature that was determined for the printing device before the current fixing temperature control method was executed, which is used to characterize the current ambient temperature of the printing device as being closest to the real environment in which it is located, i.e., the original current ambient temperature.

[0063] For each ambient temperature range, there is a corresponding device saturation temperature, which is the highest temperature the printing device can reach within the current ambient temperature range. The current ambient temperature is unaffected by the heat accumulated during printing, meaning it closely approximates the actual ambient temperature.

[0064] For example, when a printer is placed in an environment of 20°C to perform a printing task, heat will gradually dissipate inside the printer. This heat dissipation will affect the readings detected by the ambient temperature sensor; for instance, the reading will gradually rise. However, the reading will not rise indefinitely. When the heat dissipation between the printer's internal components and the external environment reaches an equilibrium point, this equilibrium point is called the thermal saturation point. The temperature corresponding to this thermal saturation point is called the device's saturation temperature. For example, if the printer is printing in an environment of 20°C, the ambient temperature sensor's reading may rise to a maximum of 30°C. At this point, 30°C is the highest temperature the printer can reach under that current ambient temperature (i.e., the device's saturation temperature). In other words, if the environment in which the printer operates does not change significantly, the device's saturation temperature is relatively constant; otherwise, it will change, meaning the highest real-time ambient temperature detected by the ambient temperature sensor will change accordingly.

[0065] Here, the device saturation temperature corresponding to the current ambient temperature can be obtained by looking up a table. Specifically, a mapping table is pre-set for each model of printing device, which records the device saturation temperature corresponding to each current ambient temperature.

[0066] After obtaining the equipment saturation temperature, calculate the absolute value of the temperature difference between the equipment saturation temperature and the current ambient temperature to obtain the first temperature difference. For example, if the current ambient temperature is 10℃ and the corresponding equipment saturation temperature is 23℃, then the absolute value of the temperature difference between the equipment saturation temperature and the current ambient temperature, i.e., the first temperature difference, is 13℃.

[0067] Next, calculate the absolute value of the temperature difference between the real-time ambient temperature and the current ambient temperature to obtain the second temperature difference. For example, if the real-time ambient temperature is 15℃, then the second temperature difference is 5℃.

[0068] After obtaining the first temperature difference and the second temperature difference, the environmental change information is determined based on the comparison of the magnitudes of the first temperature difference and the second temperature difference, thereby determining whether the ambient temperature of the environment where the printing equipment is located has changed significantly.

[0069] In this embodiment of the application, based on the comparison between the magnitude of the first temperature difference and the second temperature difference, the environmental change information of the environment in which the printing device is located is determined, including: If the second temperature difference is less than the first temperature difference, then the environmental change information is determined to be that the environmental change amplitude of the environment in which the printing device is located is less than or equal to the preset amplitude threshold. If the second temperature difference is greater than or equal to the first temperature difference, then the environmental change information is determined to be that the environmental change amplitude of the environment in which the printing device is located is greater than the preset amplitude threshold.

[0070] If the second temperature difference is less than the first temperature difference, it indicates that the environment in which the printing device is located has not changed significantly, that is, the environmental change range of the printing device is less than or equal to the preset range threshold.

[0071] If the second temperature difference is greater than or equal to the first temperature difference, it indicates that the environment in which the printing device is located has changed significantly, that is, the change in the environment in which the printing device is located is greater than the preset threshold.

[0072] As described above, the device saturation temperature indicates the highest temperature the printing device can reach under the current ambient temperature. When the environment remains relatively stable, the highest temperature that the ambient temperature sensor can detect is the device saturation temperature corresponding to the current ambient temperature. Therefore, based on the determined current ambient temperature, device saturation temperature, and real-time ambient temperature (the value detected by the ambient temperature sensor), it is possible to identify whether there have been significant changes in the environment in which the printing device operates. This eliminates the need for additional detection devices, reducing costs, and allows for more accurate analysis of environmental changes in the printing device, thus providing a basis for determining the current ambient temperature.

[0073] In this embodiment, step S103, based on the operating status and environmental change information, determines the new current ambient temperature of the printing device from the real-time ambient temperature and the first ambient temperature, specifically including the following steps: Step S21: When the operating state is determined to be the first state, and the environmental change amplitude of the environment where the printing device is located is determined to be less than or equal to the preset amplitude threshold based on the environmental change information, the minimum environmental temperature between the real-time environmental temperature and the first environmental temperature is determined as the new current environmental temperature; wherein, the first state is used to indicate that the printing device has reached the specified operating temperature.

[0074] One option is to determine the first ambient temperature as the new current ambient temperature when the real-time ambient temperature is greater than or equal to the first ambient temperature.

[0075] Here, based on environmental change information, if the magnitude of the environmental change in the environment where the printing device is located is less than or equal to a preset threshold, it indicates that the environment in which the printing device is located has not changed significantly. In other words, if the printing device is in the first state (i.e., warm-up state) and the environment in which the printing device is located has not changed significantly, then the increase in the detected value of the ambient temperature sensor is due to the diffusion of heat accumulated inside the printing device. In this case, the previously determined ambient temperature is continued to be used as the current ambient temperature.

[0076] For example, suppose that before determining whether to update the current ambient temperature, the previously determined ambient temperature is used as the current ambient temperature. At this time, the temperature of the environment around the printing device is collected at preset time intervals, obtaining multiple temperature values. The average of these multiple temperature values ​​is calculated to obtain the real-time ambient temperature. Let's assume the calculated real-time ambient temperature is 30℃. Calculations show that the second temperature difference between the real-time ambient temperature and the previous current ambient temperature is less than the first temperature difference between the device's saturation temperature and the previous current ambient temperature. This indicates that the environment around the printing device has not changed significantly, and the total number of pages printed or the total printing time within the preset period confirms that the printing device is in a warm-up state. Comparison shows that the real-time ambient temperature is greater than the first ambient temperature, meaning the ambient temperature sensor reading has increased. Since the external environment of the printing device has not changed significantly, the reason for the increased ambient temperature sensor reading is the dissipation of heat accumulated inside the printing device. Therefore, the previously determined ambient temperature is continued to be used as the current ambient temperature.

[0077] Another option is to determine the real-time ambient temperature as the new current ambient temperature when the real-time ambient temperature is lower than the first ambient temperature.

[0078] Here, determining that the environmental change amplitude of the printing device's environment is less than or equal to a preset amplitude threshold based on environmental change information indicates that the environment in which the printing device is located has not changed significantly. In other words, if the printing device is in the first state (i.e., warm-up state), and the environment in which the printing device is located has not changed significantly. However, in this case, there may be situations where the real-time ambient temperature is lower than the first ambient temperature. For example, the ambient temperature sensor may not be affected by heat diffusion for various reasons; for example, the user may turn on the air conditioner while the printing device is running, or the user may open a window in winter; however, turning on the air conditioner or opening the window is insufficient to cause the change amplitude of the external environment to exceed the preset amplitude threshold. However, turning on the air conditioner or opening the window can reduce the detected value of the ambient temperature sensor due to the lack of heat diffusion.

[0079] In other words, if the environment in which the printing equipment is located does not change significantly, the decrease in the reading from the ambient temperature sensor is because the sensor itself is not affected by heat dissipation. In this case, the real-time ambient temperature collected by the sensor more accurately reflects the true ambient temperature of the environment in which the printing equipment is located. Therefore, by setting this real-time ambient temperature as the new current ambient temperature, the fixing strategy determined based on this new current ambient temperature will also be more accurate.

[0080] For example, suppose the printer is operating in a warm-up state, and the previous ambient temperature determined for the printer was 30°C, which is taken as the current ambient temperature, with a corresponding saturation temperature of 45°C. Now, the user turns on the air conditioner and adjusts it to 23°C. The real-time ambient temperature obtained by the ambient temperature sensor is 26°C. Calculations show that the absolute value of the temperature difference between the real-time ambient temperature and the previous current ambient temperature is less than the absolute value of the temperature difference between the saturation temperature and the previous current ambient temperature. This indicates that the environment in which the printer operates has not changed significantly, but a slight change in the external environment has caused the ambient temperature sensor's reading to decrease. In this case, the printer will adopt the real-time ambient temperature as the new current ambient temperature.

[0081] As described above, when the printing device is in a warm-up state and the environment in which the printing device is located has not changed significantly, if the detected value of the ambient temperature sensor is higher than the first ambient temperature, it indicates that the heat accumulated in the printing device is dissipating. If the detected value of the ambient temperature sensor is lower than the first ambient temperature, it indicates that although the environment in which the printing device is located has not changed significantly, it has still changed slightly. In this case, a fixing strategy needs to be formulated according to the real-time ambient temperature.

[0082] In this embodiment, step S103, based on the operating status and environmental change information, determines the new current ambient temperature of the printing device from the real-time ambient temperature and the first ambient temperature, including: Step S31: When the operating state is determined to be in the first state, and the environmental change amplitude of the environment where the printing device is located is determined to be greater than the preset amplitude threshold based on the environmental change information, the real-time ambient temperature is determined as the new current ambient temperature; wherein, the first state is used to indicate that the printing device has reached the specified operating temperature.

[0083] Here, if the printing device is in a warm-up state and the environment in which the printing device is located has changed significantly, the printing device can determine the real-time ambient temperature as the new current ambient temperature.

[0084] For example, users in areas with large diurnal temperature differences (such as central and southern Xinjiang, northern Tibet, Qinghai, western Gansu, and Ningxia, where the diurnal temperature difference may exceed 15°C), or in outdoor usage scenarios (such as outdoor exhibitions and outdoor medical testing), or when switching from extremely low-temperature environments (such as cold storage) to normal temperature environments, may experience significant temperature variations. In the morning, when the printer is turned on, the ambient temperature may be low, with the outside temperature of the printing equipment possibly being 16-17°C. However, at noon, the ambient temperature may reach above 30°C.

[0085] For example, suppose a user uses a printer outdoors where there is a significant temperature difference between day and night, and the printer is operating in a warm-up state. If the previously determined ambient temperature for the printer was 15°C, and the corresponding saturation temperature of the printer was 30°C, and after some time, the ambient temperature sensor detects a real-time ambient temperature of 35°C, calculations show that the temperature difference between the real-time ambient temperature and the initial ambient temperature is greater than the temperature difference between the device saturation temperature and the initial ambient temperature. This indicates a significant change in the environment in which the printer operates. In this case, the real-time ambient temperature is determined as the new current ambient temperature.

[0086] In this embodiment of the application, step S103, which determines the new current ambient temperature of the printing device from the real-time ambient temperature and the first ambient temperature based on the operating status and environmental change information, further includes: When the operating state is determined to be the second state, the real-time ambient temperature is set as the new current ambient temperature; the second state is used to indicate that the printing device has not reached the specified operating temperature.

[0087] If the printer is in the second state (i.e., cold state), it indicates that the total number of pages printed within the preset time period has not exceeded the preset number of pages, or the total printing time within the preset time period has not exceeded the preset time. In this state, it can be determined that the number of print jobs performed by the printer is relatively small, and little heat has accumulated inside the printer. In the cold state, the small amount of heat accumulated inside the printer usually does not affect the detection value of the ambient temperature sensor. Therefore, if the printer's operating state is determined to be the second state, the real-time ambient temperature can be determined as the new current ambient temperature.

[0088] For example, after the printer is powered on, it detects the real-time ambient temperature using an ambient temperature sensor and formulates a fixing strategy based on the first detected real-time ambient temperature. Then, it calculates the real-time ambient temperature every preset time interval and determines the printer's operating status based on the total number of pages printed or the total printing time within a preset period. If the total number of pages printed within the preset period is less than a preset number of pages, or the total printing time is less than a preset time, the printer is determined to be in a cold state. In this case, a new current ambient temperature is determined based on the detected real-time ambient temperature, and a fixing strategy is determined based on this new current ambient temperature. After a period of time, the printer is determined to be in a warm state based on the total number of pages printed or the total printing time. At this point, a new current ambient temperature can be determined from the first ambient temperature and the real-time ambient temperature based on the environmental changes in the environment in which the printer is located.

[0089] The above processing method can accurately analyze the current ambient temperature of the printing equipment, thereby improving the accuracy of the fixing strategy and alleviating the technical problem of incorrect fixing strategy caused by misjudgment of ambient temperature due to overheating caused by heat accumulation inside the printing equipment.

[0090] The following is combined with Figure 2 The above-mentioned fixing temperature control method is introduced, such as... Figure 2 As shown, the method specifically includes the following steps: S201: Printing equipment is powered on; S202: Record the ambient temperature determined when the printing equipment is turned on, and obtain the current ambient temperature; S203: Collect multiple temperature values ​​of the environment where the printing device is located at preset time intervals, and calculate the average value of the multiple temperature values ​​to obtain the real-time ambient temperature; S204: Record the total number of pages printed by the printing device within a preset time period; S205: Determine whether the total number of printed pages is greater than or equal to the preset number of pages; if it is, then execute S206; otherwise, execute S209. S206: Determine whether the second temperature difference is less than the first temperature difference; wherein, the second temperature difference is the temperature difference between the real-time ambient temperature and the current ambient temperature, and the first temperature difference is the temperature difference between the equipment saturation temperature and the current ambient temperature; wherein, if it is determined that it is, then execute S207; otherwise execute S209. S207: Determine whether the real-time ambient temperature is greater than or equal to the first ambient temperature; if it is, then execute S208; otherwise, execute S209. S208: Set the first ambient temperature as the new current ambient temperature; S209: Set the real-time ambient temperature as the new current ambient temperature.

[0091] In practice, the ambient temperature T of the printer is recorded after the printing device is turned on. 初始环境 This is taken as the current ambient temperature. Then, a temperature value is collected every t min (a preset time interval), and the average of the collected temperature values ​​is calculated to obtain T. 实时环境温度 Simultaneously, the printing device records the total number of pages printed within a preset time period, denoted as page A. Then, the printing device determines its operating status based on the total number of pages printed. If A ≥ B (where B is the preset number of pages), the printing device is determined to be in warm-up mode. At this point, the comparison between the second temperature difference and the first temperature difference is further determined. If the second temperature difference T is determined... 采集（实时环境温度） -T 初始环境 (The original current ambient temperature) is less than the first temperature difference ΔT 饱和 Then continue to judge T. 实时环境温度and the first ambient temperature T 上一次环境温度 The size between them, where the first ambient temperature is T. 初始环境 If T is determined 实时环境温度 Greater than or equal to T 上一次环境温度 Then T 上一次环境温度 The new current ambient temperature is determined, meaning the original current ambient temperature remains unchanged. Since the actual external environment hasn't changed significantly, the increase in the temperature reading from the printer's internal temperature sensor is due to the dissipation of heat accumulated inside the printer; therefore, the original current ambient temperature remains unchanged. If T... 实时环境温度 Less than T 上一次环境温度 Then T 实时环境温度 Replace the old ambient temperature with the new current ambient temperature. In this case, since the external ambient temperature of the printing equipment does not change significantly, but the ambient temperature T collected by the printing equipment has decreased, it indicates that the ambient temperature sensor is not affected by the dissipation of heat accumulated inside the printing equipment, and the real-time ambient temperature is a feedback of the true environmental value. If the second temperature difference T is determined... 采集（实时环境温度） -T 上一次环境温度 (The original current ambient temperature) is greater than or equal to the first temperature difference ΔT 饱和 Then directly put T 实时环境温度 Replace with the current ambient temperature. In this case, because the ambient temperature outside the printing equipment has changed significantly, it is necessary to update to the current ambient temperature.

[0092] If A < B, then the printing device is considered to be in a cold state, and in this case, T is directly set. 实时环境温度 Replace it with the new current ambient temperature. Finally, the printing device formulates a fixing strategy based on the current ambient temperature.

[0093] Among them, T 实时环境温度 A: Real-time ambient temperature collected by the printing equipment; B: Total number of pages printed by the printing equipment within a preset time period; △T 饱和 △T is the difference between the saturation temperature of the printing equipment and the current ambient temperature. For example, if the current ambient temperature of the printing equipment is 10°C, and the saturation temperature of the printing equipment at that ambient temperature is 23°C, then △T is the difference between the saturation temperature of the printing equipment and the current ambient temperature. 饱和 =23-10=13℃.
