[0002] Nowadays, in the field of printers, some can support continuous printing of thousands of pages, at which time the temperature inside the machine will be relatively high, especially in the fixing part. Overheating can cause the paper to curl too much, which greatly affects the user experience. In order to solve the problem of too much paper curling, a fan is usually used to cool the machine. However, if the cooling capacity of the fan is not enough, the fixing temperature will still be too high even after using the fan to cool it.

Therefore, if the driving capacity of the fan is not appropriate, it will easily affect the printing work.

[0045] The technical scheme of the fan gear correction method provided in the embodiment of the present application comprises the following steps: in response to a trigger event, a first temperature, a second temperature and a first time are acquired, the first time being an actual time for heating the fixing assembly from the first temperature to the second temperature; a second time is acquired, the second time being a target time corresponding to first environment information, the first environment information being environment information inside the image forming device; and when the first time is less than the second time, the fan gear is corrected.

[0046] Figure 2 The flow chart of another fan gear correction method provided in the embodiment of the present application is shown in FIG. 4, and the method comprises the following steps: Figure 2

[0047] In step 201, in response to a trigger event, a first temperature, a second temperature and a first time are acquired, the first time being an actual time for heating the fixing assembly from the first temperature to the second temperature.

[0048] In the embodiment of the present application, each step is executed by the image forming device. For example, the image forming device is a printer or the like.

[0049] An exemplary Figure 3 The hardware structure of the image forming device in the embodiment of the present application is shown in FIG. 3. Figure 4 The software structure of the image forming device in the embodiment of the present application is shown in FIG. 4. Figure 3 As shown in FIG. 3, the hardware of the image forming device comprises a data board, an imaging assembly, a paper conveying assembly, a fixing assembly, a fan assembly and a temperature control assembly; wherein the data board can control the imaging assembly, the paper conveying assembly, the fixing assembly, the fan assembly and the temperature control assembly. Figure 4 As shown in FIG. 4, the software of the image forming device comprises an imaging control module, a conveying control module, a fixing control module, a fan control module and a temperature control module; wherein the imaging control module is used to control the imaging assembly; the conveying control module is used to control the paper conveying assembly; the fixing control module is used to control the fixing assembly; the fan control module is used to control the fan assembly; and the temperature control module is used to control the temperature control assembly.

[0050] ​Exemplarily, the triggering event comprises one or a combination of a machine preheating event, a last job entering an overspeed print mode event, a fan rotating time reaching a preset time event, and a user operation event on the first control.

[0051] Generally, a laser printer is preheated, and there are lamp tube and heating sheet. The lamp tube must reach a certain temperature to work. When the temperature of the machine is lower than the value, it will automatically preheat.

[0052] The fan rotating time reaching a preset time event comprises: a fan cumulative rotating time being equal to a first preset time, or a fan current rotating time being equal to a second preset time.

[0053] The fan cumulative rotating time is a cumulative rotating time of the fan from the first rotation to the present.

[0054] The printer fixation refers to a heating component of the printer, also called a fixation component. Laser printer printing needs to go through charging, exposure, transfer, and finally fix the image on the medium. Currently, the hot fixation method is generally used. The printed medium that has been transferred passes through the gap between the upper and lower rollers of the fixation component, and the developer is melted and penetrated into the paper fibers under high temperature and high pressure, that is, fixation is achieved.

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

[0056] Preferably, the fan gear is corrected before entering the normal printer in the embodiment of the present application, so as to use the corrected fan gear for heat dissipation during normal printing, so as to prevent the problem of insufficient heat dissipation capacity caused by fixed gear.

[0057] The fan gear correction method provided by the embodiment of the present application is introduced in detail by taking the example that the printer uses the fan gear correction method provided by the embodiment of the present application to correct the fan gear before entering printing. Figure 5 The flowchart of the printer of the embodiment of the present application for correcting the fan gear before entering printing is shown in FIG. Figure 5 After the printer is started, the fan correction flow is applied. First, the fixation control module heats the fixation component to TMP1 temperature and maintains the temperature; wherein TMP1 temperature is a first temperature. Then, the fan control module starts the fan, and opens the driving capacity of the fan to A gear. The fan control can be controlled by PWM duty cycle and the like.

[0058] For example, the duty cycle design can be divided into 10 gears, i.e. S1-S10 gears, or more or less gears can be added or reduced according to actual conditions. Among them, the duty cycles corresponding to S1-S10 gears are 10%, 20%, 30%, …, 100% respectively. For example, gear A defaults to S1 gear.

[0059] Then, as shown in Figure 5 , the fixing control module continues to heat the fixing assembly to the TEMP2 temperature after the fan is driven to the A gear and stabilized. And record the first time T1 consumed from the TEMP1 temperature to the TEMP2 temperature. Among them, the TEMP2 temperature is the second temperature.

[0060] Among them, the size of the first temperature and the second temperature is affected by many factors, such as the type of toner, the structure of the fixing assembly, the specifications of the image forming device, etc. The size of the first temperature and the second temperature can be preset.

[0061] Step 202, obtaining 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.

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

[0063] In some possible embodiments, as shown in Figure 6 , step 202 specifically includes steps 202a-202b.

[0064] Step 202a, obtaining the first environmental information;

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

[0066] Exemplarily, the first mapping relationship can be in the form of a table, which is a pre-established mapping relationship.

[0067] Exemplarily, the target time is a target heating time when the fixing heating and the fan cooling are performed under a certain environmental information.

[0068] As shown in Figure 5 , the temperature control module of the printer collects the current internal temperature and humidity of the machine, and according to the collected temperature and humidity, obtains the second time TAX by looking up the first table. The first table contains the correspondence between the environmental information and the target time, and the specific table form is determined according to the machine state.

[0069] For example, the first table can be a target heating time table of fixing heating and fan cooling 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 time table of different environment fixing heating, fan cooling

[0071]

[0072] Step 203, judge 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 cooling capacity of the fan by judging whether the first time, i.e. the actual time, from the first temperature to the second temperature meets the second time, i.e. the target time corresponding to the current environmental state condition.

[0074] Step 204, do not correct the fan gear. The flow ends.

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

[0076] Step 205, correct the fan gear.

[0077] In this step, the first time is less than the second time, which means that the time from the first temperature to the second temperature is faster, indicating that the cooling capacity of the fan is insufficient. If the current gear of the fan is not the maximum gear, the fan gear can be corrected. If the current gear of the fan is the maximum gear, an abnormal prompt information is output, for example, "clean the cotton and dust on the cooling fan port and fan page, if it has been cleaned, please contact the after-sales service, otherwise it may reduce the printing performance".

[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 cooling capacity of the fan is insufficient, the gear of the fan needs to be adjusted to a higher gear, which can be adjusted to a higher gear by several gears at a time.

[0080] Optionally, the specific number of gears to be adjusted higher 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, the gear can be adjusted to a higher gear by one gear; if the absolute value of the difference between the first time and the second time is large, the gear can be adjusted to a higher gear by several gears.

[0081] The embodiment of the present application determines whether the fan satisfies the heat dissipation capacity by judging whether the actual time from the first temperature to the second temperature satisfies the corresponding target time under the current environmental information, and corrects the fan gear if not. The embodiment of the present application can correct the heat dissipation error between design and actuality, improve the heat dissipation capacity of the printer, and the correction method is simple and easy to implement, which helps to reduce program redundancy and provides another implementable way to improve the heat dissipation capacity by correcting the fan gear to meet different use requirements.

[0082] Step 206, the third temperature, the fourth temperature and the third time are obtained, the third time being the actual time for heating the fixing assembly 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 judge whether the corrected gear satisfies the heat dissipation requirement.

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

[0085] 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 third temperature and the fourth temperature can be preset.

[0086] Step 207, the fourth time is obtained, the fourth time being the target time corresponding to the second environmental information, and the second environmental information being the environmental information inside the image forming device.

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

[0088] Step 208, it is judged whether the third time is greater than or equal to the fourth time, if yes, step 209 is executed, and if not, step 210 is executed.

[0089] This step confirms the heat dissipation capacity of the fan by judging whether the third time, i.e. the actual time for heating from the third temperature to the fourth temperature, satisfies the fourth time, i.e. the target time corresponding to the current environmental state, to judge whether the corrected fan gear satisfies the heat dissipation requirement.

[0090] Step 209, the corrected offset or the corrected fan gear is stored in association with the first environmental information, and the corrected offset being the offset of the corrected fan gear relative to the fan gear before correction. The flow ends.

[0091] In this step, it is judged that the third time is greater than or equal to the fourth time, indicating 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 at the S1 gear, the fan gear needs to be adjusted according to the correction offset or the corrected fan gear associated with the first environmental information.

[0092] For example, the fan gear before correction is S1 gear (duty cycle is 10%), and the fan gear after correction is S3 (duty cycle is 30%), so 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 the fan is driven stably at the S1 gear, the fan gear needs to be increased by 20% offset.

[0093] For example, as shown in Figure 5 If the first time T1 is less than the second time T2, one fan gear is raised, and when the raised gear is not the maximum gear, it is judged whether the corrected gear meets the heat dissipation requirement, and if it meets the heat dissipation requirement, the corrected gear is recorded.

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

[0095] Step 210, judge whether the corrected fan gear is a high gear; if yes, execute step 212; if no, execute step 214.

[0096] In this step, it is judged that the third time is less than the fourth time, indicating that the corrected fan gear does not meet the heat dissipation requirement, so the correction fails. After determining that the correction fails, it is judged whether the corrected fan gear is a high gear, so as to judge whether an abnormal prompt is needed.

[0097] For example, the high gear includes a first high-level gear or a second high-level gear.

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

[0099] For example, the first high-level gear is S8 gear, and the second high-level gear is S10 gear.

[0100] Step 212, confirm the fan abnormality and display the abnormal prompt information corresponding to the high gear. The flow ends.

[0101] If it is judged that the corrected fan gear is the high gear, the fan is abnormal, and the abnormal prompt information corresponding to the high gear is displayed.

[0102] The reasons for the fan abnormality include lint and dust on the heat dissipation fan port and fan page, old fan with decreased driving capacity, or damaged fan.

[0103] For example, the abnormal prompt information corresponding to the first high gear can be 'clean the lint and dust on the heat dissipation fan port and fan page, otherwise the printing performance may be reduced'.

[0104] For example, the abnormal prompt information corresponding to the second high gear can be 'clean the lint and dust on the heat dissipation fan port and fan page, if it has been cleaned, please contact the after-sales service, otherwise the printing performance may be reduced'.

[0105] For example, as shown in FIG. 5, if the corrected gear does not meet the heat dissipation requirement, it is determined according to the fan gear condition whether the user needs to be notified to clean the fan or the after-sales service needs to be contacted for repair. Figure 5

[0106] When it is confirmed that the correction fails, the abnormal prompt information can prompt the user to clean the fan lint and dust in time, and reduce the influence on the normal working state of the machine. If the fan heat dissipation performance is still poor after the user cleans it, the user can be prompted to contact the after-sales service for repair.

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

[0108] In this step, if it is judged that the corrected fan gear is not the high gear and not the maximum gear, it is confirmed that the fan is not abnormal, and the fan gear can be continued to be corrected.

[0109] In summary, the embodiment of the present application judges 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 decreases, the fan driving capacity is increased. If the fan driving capacity exceeds the rated driving capacity, the user can be prompted to clean the lint and dust on the fan port and fan page. If the fan is old with decreased driving capacity or damaged, the user can be prompted to contact the after-sales service for replacement. It is ensured that the fan heat dissipation performance is always guaranteed, and the machine always works at the normal printing speed.

[0121] In the technical solution of the fan speed correction device provided in this embodiment of the invention, in response to a trigger event, a first temperature, a second temperature, and a first time are acquired.

A second time is acquired, which is a target time corresponding to first environmental information, which is the environmental information inside the image forming apparatus. When the first time is less than the second time, the fan speed is corrected. In this embodiment, in response to a trigger event, it can determine whether the actual time for the fixing component to heat from the first temperature to the second temperature is less than the corresponding target time in the environment inside the image forming apparatus, thereby determining whether the fan's heat dissipation capacity meets the requirements. If not, the fan speed is corrected. This ensures the fan's heat dissipation capacity when the image forming apparatus enters the printing state, reducing the impact on normal operation, such as ensuring it always operates at the normal printing speed. The fan speed correction in this embodiment is simple and easy to implement, helping to reduce program redundancy while improving printing efficiency and the reliability of fan drive performance.
