[0001] The present invention relates to the field of fan control, and in particular to a fan gear position correction method, device and image forming device. [Background technology]

[0002] Nowadays, in the field of printers, some can support continuous printing of thousands of pages. At this time, the temperature inside the machine will be relatively high, especially the fixing part. Overheating will cause the paper curl rate to be too high, which will greatly affect the user experience. In order to solve the problem of excessive paper curl rate, a fan is usually used to dissipate heat from the machine. However, if the fan's heat dissipation capacity is insufficient, even after using the fan to dissipate heat, the fixing temperature will still be too high. At this time, it will generally enter the reduced speed printing mode and print by increasing the spacing between the printing papers, which will reduce the printing efficiency to a certain extent. Therefore, if the fan's driving capacity is not appropriate, it will easily affect the printing work. [Summary of the invention]

[0037] 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.

[0038] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the 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.

[0040] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0041] Figure 1 A flow chart of a fan gear correction method provided by an embodiment of the present invention, such as Figure 1 As shown, the method includes:

[0042] Step 101 : In response to a triggering event, a first temperature, a second temperature and a first time are acquired, where the first time is the actual time for the fixing component to be heated from the first temperature to the second temperature.

[0043] Step 102 : Acquire a second time, where the second time is a target time corresponding to the first environmental information, and the first environmental information is environmental information inside the image forming device.

[0044] Step 103: When the first time is less than the second time, calibrate the fan gear position.

[0045] In a technical solution of a fan gear correction method provided by an embodiment of the present invention, an image forming device responds to a trigger event, obtains a first temperature, a second temperature and a first time, the first time is the actual time for the fixing component to heat from the first temperature to the second temperature; obtains a second time, the second time is a target time corresponding to the first environmental information, and the first environmental information is the environmental information inside the image forming device; when the first time is less than the second time, the fan gear is corrected. In the embodiment of the present application, it is possible to respond to a trigger event to determine whether the time for the fixing component to heat from the first temperature to the second temperature is less than the corresponding target time under the environment inside the image forming device, so as to determine whether the heat dissipation capacity of the fan meets the requirements, and if not, the fan gear is corrected. In addition, the heat dissipation capacity of the fan can be guaranteed when the image forming device enters the printing state, so that it always works at a normal printing speed. The correction of the fan gear in the embodiment of the present application is simple and easy to implement, and can improve printing efficiency and the reliability of fan driving performance while helping to reduce program redundancy.

[0046] Figure 2 A flow chart of another fan gear correction method provided by an embodiment of the present invention, such as Figure 2 As shown, the method includes:

[0047] Step 201 : In response to a trigger event, a first temperature, a second temperature and a first time are acquired, where the first time is the actual time for the fixing component to be heated from the first temperature to the second temperature.

[0048] In the embodiment of the present invention, each step is performed by an image forming device, for example, the image forming device is a printer.

[0049] For example, Figure 3 is a schematic diagram of the hardware structure of an image forming device in an embodiment of the present invention, Figure 4 FIG. 1 is a schematic diagram of the software structure of the image forming device in an embodiment of the present invention. Figure 3 As shown, the hardware of the image forming device includes a data board, an imaging component, a paper moving component, a fixing component, a fan component and a temperature control component; wherein the data board can control the imaging component, the paper moving component, the fixing component, the fan component and the temperature control component. Figure 4 As shown, the software of the image forming device includes an imaging control module, a conveying control module, a fixing control module, a fan control module and a temperature control module. Among them, the imaging control module is used to control the imaging component; the conveying control module is used to control the paper moving component; the fixing control module is used to control the fixing component; the fan control module is used to control the fan component; and the temperature control module is used to control the temperature control component.

[0050] Exemplarily, the triggering event includes one or a combination of a machine preheating event, an event that the last job entered an over-speed reduction printing mode, an event that the fan rotation time reaches a preset time, and an event that the user operates the first control.

[0051] Generally, laser printers preheat, and there are lamp tubes and heaters. The lamp tube must reach a certain temperature to work. When the machine temperature is lower than this value, it will automatically preheat.

[0052] The event that the rotation time of the fan reaches the preset time includes: the event that the cumulative rotation time of the fan is equal to the first preset time, or the event that the current rotation time of the fan is equal to the second preset time.

[0053] The accumulated rotation time of the fan is the accumulated rotation time of the fan from the first rotation to the current rotation.

[0054] Printer fixing refers to the heating component of the printer, also called the fixing component. Laser printer printing requires de-charging, exposure, transfer, and finally fixing the image on the medium. At present, thermal fixing is generally used. The transferred print medium passes through the slit between the upper and lower rollers of the fixing component. Under high temperature and high pressure, the developer melts and penetrates into the paper fiber, thus achieving fixing.

[0055] The fan gear correction method provided in the embodiment of the present invention can correct the fan gear before the image forming device enters printing, or can correct the fan gear during printing. It should be noted that if the fan gear correction method provided in the embodiment of the present invention is executed during printing, printing needs to be paused and printing can be continued after the fan gear correction is completed.

[0056] Preferably, the embodiment of the present invention calibrates the fan gear position before entering the normal printer, so that the calibrated fan gear position can be used for heat dissipation during normal printing, thereby preventing the problem of insufficient heat dissipation capacity caused by a fixed gear position.

[0057] Taking the example of a printer correcting the fan gear position using the fan gear position correction method provided by an embodiment of the present invention before printing, the fan gear position correction method provided by an embodiment of the present invention is described in detail. Figure 5 FIG. 1 is a schematic diagram of a process of correcting the fan gear position of a printer before printing according to an embodiment of the present invention. Figure 5 As shown, after the printer is turned on, it applies to enter the fan calibration process. First, the fixing control module heats the fixing component to TMP1 temperature and maintains the temperature; wherein TMP1 temperature is the first temperature. Then, the fan control module starts the fan and turns the fan's driving capacity to A gear. The fan control can be controlled by PWM duty cycle and other methods.

[0058] For example, according to the duty cycle design, it can be divided into 10 gears, namely S1 to S10 gears, and the gears can be increased or decreased according to the actual situation. Among them, the duty cycles corresponding to S1 to S10 gears are 10%, 20%, 30%, ..., 100% respectively. For example, gear A defaults to gear S1.

[0059] Then, if Figure 5 As shown, after the fan is driven to the A gear and stabilized, the fixing control module continues to heat the fixing component to the TEMP2 temperature, and records the first time T1 consumed from the TEMP1 temperature to the TEMP2 temperature, wherein the TEMP2 temperature is the second temperature.

[0060] The magnitude of the first temperature and the second temperature is affected by various factors, such as the type of toner, the structure of the fixing assembly, the specification of the image forming device, etc. The magnitude of the first temperature and the second temperature may be preset.

[0061] Step 202: Acquire a second time, where the second time is a target time corresponding to the first environmental information, and the first environmental information is environmental information inside the image forming device.

[0062] Exemplarily, the environmental information includes temperature and humidity.

[0063] In some possible embodiments, Figure 6 As shown, step 202 specifically includes: step 202a-step 202b.

[0064] Step 202a, obtaining first environment information;

[0065] Step 202b: obtain the second time according to the first environmental information and the first mapping relationship, where the first mapping relationship is a one-to-one correspondence between the environmental information and the target time.

[0066] Exemplarily, the first mapping relationship may be in a table format and may be a pre-established mapping relationship.

[0067] Exemplarily, the target time is a target heating time when the fuser is heated and the fan is cooled under certain environmental information.

[0068] like Figure 5 As shown, the temperature control module of the printer collects the current internal temperature and humidity of the machine, and obtains the second time TAX by searching the first table according to the collected temperature and humidity. The first table contains the corresponding relationship between environmental information and target time, and the specific table format depends on the machine status.

[0069] For example, the first table may be a target heating time table for fixing heating and fan heat dissipation under different environments as shown in Table 1. As shown in Table 1, TA1-TA135 represent 135 target heating times.

[0070] Table 1 Target heating schedule for fixing heating and fan cooling in different environments

[0071]

[0072] Step 203 , determine whether the first time is less than the second time, if not, execute step 204 ; if yes, execute step 205 .

[0073] This step confirms the heat dissipation capacity of the fan by determining whether the first time, i.e., the actual time, of heating from the first temperature to the second temperature meets the second time, i.e., the target time corresponding to the current environmental conditions. If the heat dissipation capacity of the fan is sufficient, heating from the first temperature to the second temperature should be slow.

[0074] Step 204: Do not calibrate the fan gear position. The process ends.

[0075] In this step, if the first time is greater than or equal to the second time, the time for heating from the first temperature to the second temperature is longer, indicating that the heat dissipation capacity of the fan is sufficient and there is no need to correct the fan gear.

[0076] Step 205, calibrate the fan gear position.

[0077] In this step, if the first time is less than the second time, the time from the first temperature to the second temperature is faster, indicating that the fan's heat dissipation capacity is insufficient. If the fan's current gear is not the maximum gear, the fan gear can be corrected. If the fan's current gear is the maximum gear, an abnormal prompt message is output, such as "Clean the lint and dust on the cooling fan port and fan leaf. If it has been cleaned, please contact after-sales service for on-site service, otherwise the printing performance may be reduced."

[0078] In some possible embodiments, step 205 specifically includes: adjusting the fan gear from a first gear to a second gear, the first gear being the current fan gear of the fan, and the second gear being higher than the first gear.

[0079] Since the fan's heat dissipation capacity is insufficient, the fan gear needs to be increased, which can be several gears at a time.

[0080] Optionally, the specific number of gears to be increased can be determined according to the absolute value of the difference between the first time and the second time. For example, if the absolute value of the difference between the first time and the second time is small, then one gear can be increased; if the absolute value of the difference between the two is large, then more gears can be adjusted.

[0081] The embodiment of the present invention determines whether the fan meets the heat dissipation capacity by judging whether the actual time of heating from the first temperature to the second temperature meets the target time corresponding to the current environmental information. If not, the fan gear is corrected. The embodiment of the present invention can correct the heat dissipation error between the design and the actual heat dissipation, improve the heat dissipation capacity of the printer, and the correction method is simple and easy to implement. While helping to reduce program redundancy, it provides another feasible method for correcting the fan gear to improve the heat dissipation capacity to meet different usage requirements.

[0082] Step 206 , obtaining a third temperature, a fourth temperature and a third time, where the third time is the actual time for the fixing assembly to be heated from the third temperature to the fourth temperature.

[0083] The purpose of obtaining the third temperature, the fourth temperature and the third time in this step is to subsequently determine whether the calibrated gear position meets the heat dissipation requirements.

[0084] The third time for the fixing assembly to be heated from the third temperature to the fourth temperature is recorded.

[0085] The magnitudes of the third temperature and the fourth temperature are affected by various factors, such as the type of toner, the structure of the fixing assembly, the specifications of the image forming device, etc. The magnitudes of the third temperature and the fourth temperature may be preset.

[0086] Step 207 : Acquire a fourth time, where the fourth time is a target time corresponding to the second environmental information, and the second environmental information is environmental information inside the image forming device.

[0087] For the introduction of step 207 , please refer to the description of the aforementioned step 202 , which will not be repeated here.

[0088] Step 208 , determine whether the third time is greater than or equal to the fourth time, if so, execute step 209 ; if not, execute step 210 .

[0089] This step confirms the heat dissipation capacity of the fan by judging whether the third time for heating from the third temperature to the fourth temperature, that is, whether the actual time meets the fourth time, that is, the target time corresponding to the current environmental conditions, to determine whether the corrected fan gear meets the heat dissipation requirements.

[0090] Step 209: store the correction offset or the corrected fan gear position in association with the first environment information, where the correction offset is the offset of the corrected fan gear position relative to the fan gear position before correction. The process ends.

[0091] In this step, if it is determined that the third time is greater than or equal to the fourth time, it indicates that the corrected fan gear can meet the heat dissipation requirement, so the correction is successful, and the correction offset is stored in association with the first environmental information, or the corrected fan gear is stored in association with the first environmental information. In the subsequent printing process, if the environmental information inside the image forming device is the first environmental information, and the fan is driven stably in the S1 gear, it is necessary to adjust the fan gear according to the correction offset stored in association with the first environmental information or the corrected fan gear.

[0092] For example, the fan position before correction is S1 (duty cycle is 10%), and the fan position after correction is S3 (duty cycle is 30%), then the correction offset is 20%; in the subsequent printing process, if the environmental information inside the image forming device is the first environmental information, and after the fan is driven stably at the S1 position, it is necessary to increase the fan position by 20% offset.

[0093] For example, Figure 5 As shown, when the first time T1 is less than the second time TAX, the fan gear is increased by one, and when the increased gear is not the maximum gear, it is determined whether the corrected gear meets the heat dissipation requirements. If the heat dissipation requirements are met, the corrected gear is recorded.

[0094] The embodiment of the present invention can correct the design and actual heat dissipation errors by correcting the fan gear position, improve the heat dissipation performance of the machine, reduce the machine entering the speed reduction mode due to excessive temperature, and thus improve the user's printing efficiency.

[0095] Step 210 , determine whether the calibrated fan gear is a high gear; if so, execute step 212 ; if not, execute step 214 .

[0096] In this step, if the third time is less than the fourth time, it indicates that the calibrated fan gear does not meet the heat dissipation requirement, so the calibration fails. After determining that the calibration fails, it is determined whether the calibrated fan gear is a high gear, so as to determine whether an abnormal prompt is required.

[0097] Exemplarily, the high gear includes a first high gear or a second high gear.

[0098] Illustratively, the first high-level gear is lower than the second high-level gear.

[0099] For example, the first highest gear position is the S8 gear position, and the second highest gear position is the S10 gear position.

[0100] Step 212: confirm that the fan is abnormal and display the abnormal prompt information corresponding to the high position. The process ends.

[0101] In this step, if it is determined that the calibrated fan gear position is a high position, the fan is abnormal and an abnormal prompt message corresponding to the high gear position is displayed.

[0102] Among them, the reasons for fan abnormality include lint and dust on the cooling fan outlet and fan leaves, the fan is old and has reduced driving ability, or the fan is damaged.

[0103] Exemplarily, the abnormal prompt message corresponding to the first high-level gear may be "clean the lint and dust on the cooling fan port and fan leaves, otherwise the printing performance may be reduced."

[0104] Exemplarily, the abnormal prompt message corresponding to the second highest level gear may be "Clean the lint and dust on the cooling fan outlet and fan leaves. If they have been cleaned, please contact after-sales service, otherwise the printing performance may be reduced."

[0105] For example, Figure 5 As shown, if the calibrated gear does not meet the heat dissipation requirements, it is determined whether it is necessary to notify the user to clean the fan or whether after-sales service is required to conduct on-site inspection and maintenance based on the fan gear situation.

[0106] The embodiment of the present invention can prompt the user to clean the fan cotton wool and dust in time through abnormal prompt information when the calibration failure is confirmed, so as to reduce the impact on the normal working state of the machine. If the heat dissipation performance of the fan is still poor after the user cleans it, the user can also be prompted to contact after-sales service for on-site inspection.

[0107] Step 214, continue to calibrate the fan gear.

[0108] In this step, if it is determined that the calibrated fan gear is not a high gear and is not a maximum gear, and it is confirmed that there is no abnormality in the fan, the fan gear can continue to be calibrated.

[0109] In summary, the embodiment of the present invention determines whether the fan heat dissipation performance has decreased by heating the fixing module and controlling the fan heat dissipation. If the fan heat dissipation performance has decreased, the fan driving capacity is improved. If the rated driving capacity of the fan is exceeded, the user can be prompted to clean the cotton wool and dust on the fan port and fan leaves. If the fan is old and the driving capacity has decreased or the fan is damaged, the user can be prompted to contact after-sales for replacement. This ensures that the fan heat dissipation performance is always guaranteed and the machine always works at normal printing speed.
