The heating temperature of the fixing is usually above 150℃, and sometimes it may reach 230℃ or higher.

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0017] Figure 1 The flowchart of one embodiment of the present invention is shown in FIG.

[0018] Figure 2 The figure is a schematic diagram of the structure of an image forming device according to an embodiment of the present invention. [Specific implementation method]

[0019] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] When performing printing or copying jobs, image forming devices such as printers and copiers need to increase the fixing temperature to the target temperature to ensure that the toner can be fully melted and fixed on the paper. In some scenarios, users need to continuously print a large number of jobs, causing the fixing temperature to be continuously maintained at the target temperature. The heat generated by the fixing components continues to accumulate inside the printer, which may cause the mechanical components or electrical components inside the printer to reduce their service life. In order to solve this problem, the prior art reduces the printing speed or stops printing when it detects that the temperature inside the printer has reached a certain value, and continues printing until the temperature drops to a normal value. However, this method reduces printing efficiency.

[0022] To this end, an embodiment of the present invention provides a fixing control method, which is executed in an image forming device, and can be specifically executed by a controller in the image forming device. The method of this embodiment is as follows Figure 1 As shown, including:

[0023] S120: Receive an image forming job.

[0024] The image forming job may specifically be a job type that requires fusing temperature control, such as a print job, a copy job, or a fax job. The image forming device may receive the image forming job from a printer panel or a terminal device. In some embodiments, the user may issue the image forming job through the operation panel of the printer, for example, the user may select the copy function through a graphical user interface on the operation panel, or may select a document pre-stored in the printer on the operation panel to generate a print job. In other embodiments, the user may operate a terminal device such as a computer or a mobile phone, select a file from the terminal device and generate a print job, and then transmit the file to the printer via a wired or wireless method.

[0025] S140: Acquire device status; the device status is determined based on the number of printed pages within a previously preset time.

[0026] In the first embodiment, the image forming device can obtain the device status when receiving the image forming job. The device status can refer to the heat status inside the device, or it can refer to whether the device is in a "continuous printing state" or a "non-continuous printing state"; more specifically, the device status can be inferred based on the number of printed pages in the previously preset time. The device status is obtained to determine whether the device may accumulate too much heat inside due to continuous printing or environmental temperature. One difference between the present invention and the prior art is that the embodiment of the present invention determines the device status based on the number of printed pages in the previously preset time, rather than obtaining the device status through the temperature sensor in the fixing component. This is because the role of the temperature sensor in the fixing component is to measure the temperature of the heating roller by contact or non-contact method, rather than measuring the ambient temperature of the internal space of the printer. If the heating roller has a certain temperature control logic, the temperature value measured by the temperature sensor may not change significantly regardless of whether the image forming device continues to print, so it is difficult to accurately determine the current device status of the image forming device by obtaining the temperature through the temperature sensor. On the other hand, when receiving an image forming job, the embodiment of the present invention obtains the number of printed pages in a period of time before, rather than the number of printed pages of the image forming job itself, in order to more accurately obtain the current device status, because the number of pages of the image forming job itself is more suitable for judging the temperature rise of the image forming device after a period of time, but it is difficult to accurately judge the current device status. Based on this, the embodiment of the present invention determines the temperature status by the number of printed pages in the previous preset time, for example, obtains the number of pages n that have been printed within the time t before receiving the image forming job, and compares it with the preset page number thresholds n1 and n2. If n≤n1, the device status of the image forming device is determined as "device low temperature state"; if n1<n<n2, the device status of the image forming device is determined as "device medium temperature state"; if n≥n2, the device status of the image forming device is determined as "device high temperature state". It should be noted that only one of the above three judgment branches can be executed, or multiple of them can be executed. The above embodiment can more accurately determine the device status of the image forming device without using the temperature sensor measurement value. The aforementioned "device low temperature" and other states are only an example, and it is also possible to determine whether the device is in the "continuous printing" state based on the number of printed pages and the page number threshold. In one embodiment, the device status may also be equivalent to the number of printed pages within the previously preset time. For example, the aforementioned number of printed pages n itself can also be used to describe the device status. It should be noted that "obtaining the device status" can be read by the controller from the storage area, or it can be obtained by the controller from an external device. It can be understood that if the controller has predetermined the device status before executing S140, the step of "obtaining the device status" may not be executed in S140, and the subsequent steps may be executed using the already determined device status.

[0027] In the second embodiment, the current fixing temperature can also be obtained when the number of pages printed in the previous preset time is obtained. For example, the number of pages n that have been printed within the time t before the image forming job is received is obtained, and the fixing temperature T is obtained. If n≤n1, and T<T1, the device state is determined as "device low temperature state"; if n≤n1, and T≥T1, the device state is determined as "device medium temperature state"; the judgment condition of the device high temperature state can remain unchanged, and it is still determined as "device high temperature state" when n≥n2. This embodiment takes into account that some printers may also accumulate a lot of heat when the number of pages printed previously is not large. For example, when thick paper is used for printing (such as envelope printing mode), some printers will extend the fixing heating time to ensure that the toner is fully fixed on the paper, which may cause thick paper printing to accumulate more heat when the same number of pages are printed. Therefore, this embodiment uses the fixing temperature to assist in judging the device state, and a more accurate judgment result may be obtained in some scenarios. The second embodiment can be used in combination with the first embodiment. For example, when judging the "medium temperature state of the equipment", if one of the two conditions "n1<n<n2" or "n≤n1, and T<T1" is met, it can be considered that the equipment is in the medium temperature state.

[0028] In the third embodiment, the number of job pages and the printing mode corresponding to each page in the number of job pages within the previously preset time can be obtained, and the page weight to be assigned to each page in the number of job pages can be determined according to the printing mode, and then the number of job pages can be weighted according to the page weight, and the result of the operation can be used as the number of printed pages. The printing mode can indicate the printing speed or paper type, for example, the printing speed will be reduced in the silent printing mode; the paper type is generally a thicker envelope in the envelope printing mode. Taking the printing speed as an example, the number of printed pages can be assigned a page weight according to the printing speed. For example, if α1 pages of paper are printed at a normal speed and α2 pages of paper are printed at a slow speed within the previous time t, the normal speed paper can be assigned a paper coefficient w1, and the slow speed paper can be assigned a paper coefficient w2, where w1>w2; then the number of printed pages n is determined as n=w1×α1+w2×α2, and the device status is determined according to the number of printed pages n by the methods in the first embodiment and the second embodiment. This embodiment takes into account that some printers have a normal speed printing mode and a slow speed printing mode. For example, some users want to reduce the motor noise generated during printing and may choose the slow speed printing mode. The slow speed printing mode will give more time for heat to be discharged when printing the same number of pages. Therefore, this embodiment assigns different weights to different printing speeds, which is more conducive to more accurate determination of the device status. It can be understood that weights can be assigned not only according to the printing speed, but also according to other printing attributes such as paper type. For example, if α1 pages of envelopes and α2 pages of plain paper were printed in the previous time, the envelope can be assigned a paper coefficient w1, and the plain paper can be assigned a paper coefficient w2, and then the same formula can be used to calculate the number of printed pages n.

[0029] In the fourth embodiment, the number of printed pages within a certain period can be detected, and when the number of printed pages within the detection period exceeds the page number threshold, the count value is accumulated. Then the count value within the preset time is obtained, and the device status is obtained according to the count value. For example, during the normal operation of the printer, with p as the period, the number of pages printed within the period is detected every p minutes. If it is more than m pages, the count value is increased by 1; when the printer receives an image forming job, the count value within the previous q minutes (q>p) is obtained, and the count value at this time represents the number of cycles exceeding the page number threshold; then the device status is determined by looking up the table according to the count value. This is because the printer may perform multiple consecutive prints with a small number of pages. Compared with printing multiple pages at a time, this method may cause the printer to perform the preheating process multiple times in a short period of time, thereby causing the printer to accumulate more heat. Therefore, this embodiment determines the device status of the printer by counting how many cycles exceed the page number threshold. This embodiment can be used simultaneously with the first, second, and third embodiments described above.

[0030] S160: Determine a fixing temperature adjustment strategy according to the device state.

[0031] In one implementation, the mapping relationship between the device state and the temperature adjustment strategy may be determined by looking up a table. For example, the following Table 1 may be pre-stored in the image forming device:

[0032] Table 1

[0033]

[0034] In Table 1, the adjustment temperature refers to the temperature to which the fixing target temperature should be reduced. Taking Table 1 as an example, when it is determined that the device state is the low temperature state, when printing the image forming job received in step S120, the fixing target temperature T0 is changed to (T0-A1)°C; similarly, if the device state is the medium temperature state, the fixing target temperature is changed to (T0-B1)°C; if the device state is the high temperature state, the fixing target temperature is changed to (T0-C1)°C. Where A1<B1<C1. In this way, the temperature adjustment strategy can be quickly determined according to the device state.

[0035] In another embodiment, the ambient temperature can also be obtained, and the fixing temperature adjustment strategy is determined according to the device state and the ambient temperature. The ambient temperature can be measured by an ambient temperature sensor, and the object measured is different from the fixing temperature measurement. The ambient temperature sensor can be set near the printer processor or the upper cover of the printer to measure the ambient temperature inside the printer so as to determine the thermal radiation effect of the fixing component on other parts of the printer. The process of determining the fixing temperature adjustment strategy according to the device state and the ambient temperature is shown in Table 2:

[0036] Table 2

[0037]

[0038]

[0039] In Table 2, it can be determined whether the ambient temperature inside the image forming device is low, medium or high according to the measured value of the ambient temperature sensor. Then, the adjustment value of the fixing target temperature can be determined by querying Table 2 according to the device state and the ambient temperature.

[0040] In yet another implementation, after the device status and the ambient temperature are determined, different temperature adjustment strategies may be allocated to different pages of the image forming job, as shown in Table 3.

[0041] Table 3

[0042]

[0043] In Table 3, after determining the device status and ambient temperature, the image forming device may not use the same adjustment temperature for all image forming jobs, but may assign different adjustment temperatures according to the printing order. This is because the image forming device may be in the preheating stage of gradually heating from normal temperature to a higher temperature when receiving the image forming job. At this time, the inside of the image forming device is likely not at the peak of heat. Therefore, it is possible not to make too many temperature adjustments in the first few pages of the image forming job. When the pages in the middle of the job are printed, the image forming device is already at the peak of heat, so more temperature adjustments should be made. For the pages in the end of the job, considering that the fixing temperature has been greatly reduced when processing the pages in the middle, the high temperature inside the device has been effectively reduced, so it is not necessary to adjust the temperature too much when processing the end of the job.

[0044] In an embodiment based on Table 3, A3>A2>A4>A1, that is, A3 is the peak value of the adjustment, and the temperature adjustment value gradually increases from A1 to A3, and then decreases to A4. It should be noted that the adjustment value mentioned in this embodiment is the value that should be subtracted from the fixing target temperature, that is, the actual fixing temperature is gradually reduced from T0-A1 to T0-A3 and then increased to T0-A4. In another embodiment based on Table 3, C1>B1>A1, that is, the adjustment value when the device is at a high temperature should be higher than the adjustment value when the device is at a low temperature; in another embodiment based on Table 3, A9>A5>A1, that is, the adjustment value when the ambient temperature is at a high temperature should be higher than the adjustment value when the ambient temperature is at a low temperature.

[0045] It can be understood that for different paper types, tables corresponding to the paper types can be made with reference to Table 1, Table 2 or Table 3. Taking Table 2 as an example, for ordinary paper, thin paper and thick paper, A1 to C3 in Table 2 can be assigned different temperature adjustment values ​​according to the paper type. Similarly, corresponding tables can also be made according to different printing speeds and printing modes. The above settings can facilitate the image forming device to quickly determine the corresponding temperature adjustment value according to parameters such as device status, ambient temperature, paper type, printing speed, etc., which is beneficial to improve the temperature adjustment response speed. Similarly, the above settings are also applicable to Table 1 and Table 3.

[0046] The above embodiment shown in S160 can reduce the temperature inside the image forming device without affecting the printing speed, so as to avoid the image forming device components from being reduced in service life due to overheating. In addition, some embodiments select the fixing temperature adjustment strategy according to the ambient temperature, and can also change the fixing temperature adjustment strategy for different pages, so that the toner will not be insufficiently melted due to the reduction of the fixing temperature.

[0047] S180: Executing a temperature control strategy for the image forming job according to the fixing temperature adjustment strategy. After the image forming device determines the fixing temperature adjustment strategy, the controller resets the fixing target temperature according to the fixing temperature adjustment strategy during the printing process.

[0048] <Application Example 1>

[0049] In this example, the preset time is t, and the time when the printer receives the image forming job is t0. The printer obtains a total of n pages of jobs received from the time (t0-t) to the time t0, and then compares n with the preset thresholds n1 and n2, and determines that n1<n<n2, and determines the device state of the image forming device as "medium temperature state". The printer pre-stores a mapping table between the device state and the fixing temperature adjustment strategy. The table is checked to find that the medium temperature state corresponds to B1℃, so the fixing target temperature is adjusted from T℃ to (T-B1)℃.

[0050] The above is the preparation work before printing. Next, the printer starts to print. The printer controls the fuser to adjust the temperature to (T-B1)℃, and performs paper feeding and imaging control to complete printing.

[0051] It can be seen that application example 1 determines that the printer has a certain basic temperature based on the number of previously printed pages, and then reduces the fixing target temperature by a certain amount so that the temperature inside the printer is not too high, thereby preventing high temperature from reducing the service life of printer components.

[0052] <Application Example 2>

[0053] The difference between this example and application example 1 is that the printer obtains that the paper corresponding to the n-page job includes both ordinary paper and thick paper, and the printer is configured to heat for a longer time when printing thick paper. The printer in this example also obtains the current fixing temperature when receiving the image forming job. The printer determines that n≤n1 and T≥T1, and thus determines the device state of the image forming device as "medium temperature state". The other processing procedures are the same as those in application example 1.

[0054] It can be seen that Application Example 2 takes into account the fact that a small number of pages may still cause a high printer temperature when printing thick paper, and can produce more accurate judgment results in some scenarios.

[0055] <Application Example 3>

[0056] The difference between this example and application example 1 is that in the job obtained by the printer, there are α1 pages printed in the normal speed mode and α2 pages printed in the slow speed mode. The mapping table stored in the printer is queried to determine that the page weight corresponding to the normal speed printing mode is w1, and the page weight corresponding to the slow speed printing mode is w2, so n=w1×α1+w2×α2 is calculated, and the fixing temperature adjustment strategy is determined according to the calculated n value. The other processing procedures are the same as those in application example 1.

[0057] It can be seen that application example 3 takes into account that different printing speeds will affect the degree of heat accumulation, and therefore assigns different weights to a page job corresponding to printing modes of different speeds, so as to more accurately determine the device status of the printer.

[0058] <Application Example 4>

[0059] The difference between this example and application example 2 is that the printer also obtains the current ambient temperature as T' (corresponding to the ambient low temperature state) through the ambient temperature sensor when receiving the image forming job, and the printer queries the mapping table to determine that when the device state is the device low temperature state and the ambient temperature is the ambient low temperature state, the fixing temperature adjustment value should be A1°C, and then the printer adjusts the fixing target temperature from T°C to (T-A1)°C. The other processing procedures are the same as those in application example 2.

[0060] It can be seen that Application Example 4 takes into account that the value obtained by the ambient temperature sensor is different from the device status and fixing temperature, and can more directly reflect the heat impact on the internal components of the printer. Therefore, adding ambient temperature as a reference variable in the mapping table can more accurately determine the device status of the printer.

[0061] <Application Example 5>

[0062] The difference between this example and application example 4 is that when the printer queries the mapping table, it also queries what kind of fixing temperature adjustment value should be assigned to each page of the image forming job. Specifically, the printer queries that when the device state is the device low temperature state and the ambient temperature is the ambient low temperature state, the corresponding adjustment value for pages 1-X1 of the image forming job is A1°C; the corresponding adjustment value for pages X1+1 to X2 is A2°C; the corresponding adjustment value for pages X2+1 to X3 is A3°C; and the corresponding adjustment value for pages X3+1 and later is A4°C. After determination, before the printer processes the job of the corresponding page sequence, it adjusts the fixing target temperature to the corresponding value. The rest of the processing is the same as application example 4.

[0063] It can be seen that Application Example 4 takes into account that different pages of the same image forming job are in different device states when being printed, so the fixing target temperature can be processed to different values ​​at different stages of the job, which helps to accurately determine the device state of the printer.
