[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] In view of the problem that when the fixing temperature is unstable due to the failure of the working parts related to the image forming device, the key parts or circuits may be damaged if the image forming device continues to work, the embodiment of the present invention provides a detection process, such as Figure 1 As shown, the detection process includes:

[0052] S101: Obtain a print job.

[0053] This application does not limit the method of obtaining print jobs. For example, the print job can be obtained from a PC (Personal Computer, referred to as PC), an APP (Application, referred to as APP), a cloud server, or a USB (Universal Serial Bus, referred to as USB) drive.

[0054] S103: Monitor the current temperature of the fixing device.

[0055] For example, the current temperature of the fuser is monitored every 0.1 seconds.

[0056] Specifically, the image forming device samples the voltage value of the current AC power supply in real time, and detects the temperature value of the current fixing module (i.e., the current fixing temperature) through a thermistor installed in the middle of the back of the fixing ceramic sheet. In addition, the image forming device also obtains the current ambient temperature value through an ambient temperature sensor.

[0057] The image forming device has a preset fixing target temperature library, and the fixing target temperature is determined by the paper type, number of pages, mechanical status, and ambient temperature.

[0058] S105: judging whether the image forming device is in a preliminary stable state according to the print job and the current fixing temperature;

[0059] S107: If it is in the preliminary stable state, perform stability detection on the current fixing temperature.

[0060] S109: If it is not in the preliminary stable state, the stability detection for the current fixing temperature is not performed.

[0061] In an optional implementation, when the image forming device is not in the preliminary stable state, the process returns to step S105 to continue to determine whether the image forming device is in the preliminary stable state based on the print job and the current fixing temperature.

[0062] In an optional embodiment, if Figure 2 As shown, step S105 includes:

[0063] S202: Determine whether the image forming device is in a preliminary stable state according to whether the print job is the first page print and the fluctuation range of the current fixing temperature relative to the fixing target temperature. If the print job is the first page print, execute step S204; if the print job is not the first page print, execute step S206.

[0064] Specifically, the image forming apparatus determines whether the print job is first page printing.

[0065] When the image forming device is working, there are many situations where the temperature is not yet stable. For example, the image forming device has just been turned on and has not been preheated, for example, it needs to be heated up when switching from standby mode to working mode. If the temperature stability test is performed at this time, the temperature stability test result will be inaccurate, and an error warning or error termination of the work will be issued. Therefore, it is necessary to determine that the image forming device has been initially stabilized before performing the temperature stability test to improve the accuracy of the temperature stability test.

[0066] S204: If the print job is the first page print, and a first preset time has passed since the print job was acquired, it is considered that the image forming device is in a preliminary stable state.

[0067] For example, the first preset duration is 10 seconds.

[0068] Specifically, when the print job is the first page print, it is determined whether a first preset time has passed since the print job was acquired; if so, it is considered that the image forming device is in a preliminary stable state; if not, it is considered that the image forming device is not in a preliminary stable state.

[0069] The current fixing temperature of the image forming device that is not turned on or in standby state is lower than the fixing target temperature in the working state (e.g., printing working state). In order to ensure that the image forming device can work normally, the current fixing temperature needs to reach the fixing target temperature, and the image forming device needs to be preheated for a certain period of time. Therefore, the first page printing needs to be preheated for a first preset period of time to ensure that the current fixing temperature is initially stable, and then the temperature stability detection is started to improve the accuracy of the temperature stability detection and reduce the temperature stability detection errors.

[0070] S206: If the print job is not the first page print, and the fluctuation range of the current fixing temperature relative to the fixing target temperature is smaller than the first preset range, it is considered that the image forming device is in a preliminary stable state.

[0071] For example, the first preset range is -10°C to 10°C.

[0072] Specifically, when the print job is not the first page print, it is determined whether the fluctuation range of the current fixing temperature relative to the fixing target temperature is less than the first preset range; if so, it is considered that the image forming device is in a preliminary stable state; if not, it is considered that the image forming device is not in a preliminary stable state.

[0073] After printing the first page, the current fixing temperature of the image forming device that performs non-first page printing has reached the fixing target temperature or is still close to the fixing target temperature. Therefore, when the image forming device performs non-first page printing, it determines that the fluctuation range of the current fixing temperature relative to the fixing target temperature is less than the first preset range, and then starts the temperature stability detection, which reduces the waiting time for the temperature stability detection of non-first page printing, performs the temperature stability detection in time, and improves the accuracy of the temperature stability detection.

[0074] In one embodiment, the present invention provides a detection process, such as Figure 3 As shown, the detection process includes:

[0075] S301: Obtain a print job.

[0076] S303: Monitor the current fixing temperature, the target fixing temperature and the working state of the image forming device.

[0077] S305: judging whether the image forming device is in a preliminary stable state according to the print job, the current fixing temperature, the target fixing temperature and the working state of the image forming device.

[0078] S307: If it is in the preliminary stable state, a stability detection for the current fixing temperature is performed.

[0079] S309: If it is not in the preliminary stable state, the stability detection for the current fixing temperature is not performed.

[0080] The image forming device is not always in a working state. For example, it changes from a standby state (non-working state) to a printing state or from a state waiting for paper type switching (non-working state) to a state where the paper type switching is completed and the printing continues. These changes from non-working state to working state may cause a sudden change in the fixing target temperature, and a sudden change in the fixing target temperature may affect the judgment of whether the image forming device is in a preliminary stable state.

[0081] In an optional embodiment, when the image forming device is not in a preliminary stable state, return to step S305 and continue to determine whether the image forming device is in a preliminary stable state based on the print job, current fixing temperature, target fixing temperature and the working status of the image forming device.

[0082] Based on the above situation, in an optional implementation, if Figure 4 As shown, step S305 includes:

[0083] S402: Determine whether the image forming device changes from a non-operating state to an operating state. If yes, execute step S404; if no, execute step S414.

[0084] For example, the working state is changed from a standby state to a printing working state.

[0085] S404: Determine whether the fluctuation range of the current fixing target temperature relative to the previous fixing target temperature is smaller than the second preset range. Execute step S406; if not, execute S414.

[0086] For example, the second preset range is -60°C to 0°C.

[0087] S406: Determine whether the current printing task is the first page printing. If yes, execute step S408; if no, execute step S410.

[0088] S408: Determine whether a first preset time has passed since the print job was acquired. If yes, execute S412; if no, execute S414.

[0089] For example, the first preset time length is 10 seconds.

[0090] S410: Determine whether the fluctuation range of the current fixing temperature relative to the fixing target temperature is smaller than the first preset range. If yes, execute S412; if no, execute S414.

[0091] For example, the first preset range is -10°C to 10°C.

[0092] S412: Determine whether the image forming apparatus is in a preliminary stable state.

[0093] S414: It is determined that the image forming apparatus is not in a preliminary stable state.

[0094] According to the method provided by the present invention, the temperature stability detection is not affected by the sudden change of the fixing target temperature caused by the change from the non-working state to the working state, thereby improving the accuracy of the temperature stability detection.

[0095] The image forming device does not necessarily work continuously during operation. For example, when the image forming device performs intermittent printing, that is, after printing a page, it will print the next page after a certain interval of several seconds. The target fixing temperature in the intermittent stage of printing two pages will be reduced by a specific value, while the current fixing temperature will remain unchanged. The fluctuation range of the current fixing temperature relative to the fixing target temperature will increase. At this time, it will result in the consequence of erroneously determining that the current fixing temperature is unstable. In addition, in the non-continuous printing logic of some image forming devices, each page printed is regarded as the first page printed. In the non-continuous printing logic of some image forming devices, only the first page of the job is regarded as the first page printed. Therefore, the non-continuous working state of the image forming device will affect the judgment of whether the image forming device is in a preliminary stable state, and will also affect the accuracy of the current fixing temperature stability detection.

[0096] Based on the above situation, in an optional implementation, if Figure 5 As shown, step S305 includes:

[0097] S501: Determine whether the current printing task is the first page printing. If yes, execute step S503; if no, execute step S505.

[0098] S503: Determine whether a first preset time has passed since the print job was acquired. If so, execute step S505; if not, execute step S507.

[0099] For example, the first preset time length is 10 seconds.

[0100] S505: Determine whether the fluctuation range of the current fixing temperature relative to the fixing target temperature is smaller than the first preset range. If yes, execute step S507; if no, execute step S513.

[0101] For example, the first preset range is -10°C to 10°C.

[0102] S507: Determine whether the image forming device is in working state. If yes, execute step S509; if no, execute step S513.

[0103] For example, the working state is an intermittent printing working state.

[0104] S509: Determine whether the fixing target temperature is the preset temperature. If yes, execute step S513; if no, execute step S511.

[0105] For example, the preset temperature is 0°C.

[0106] S511: Determine whether the image forming apparatus is in a preliminary stable state.

[0107] S513: It is determined that the image forming apparatus is not in the preliminary stable state.

[0108] According to the method provided by the present invention, the temperature stability detection is not affected by the change of the fixing target temperature caused by the intermittent printing performed by the image forming device, and the accuracy of the temperature stability detection is further improved.

[0109] In an optional embodiment, if Figure 6 As shown, step S305 includes:

[0110] S602: Determine whether the fluctuation range of the current fixing target temperature relative to the previous fixing target temperature is less than a second preset range. Execute step S604; if not, repeat step S602.

[0111] For example, the second preset range is -60°C to 0°C.

[0112] S604: Determine whether the current printing task is the first page printing. If yes, execute step S606; if no, execute step S608.

[0113] S606: Determine whether a first preset time has passed since the print job was acquired. If yes, execute step S608; if no, execute step S610.

[0114] For example, the first preset time length is 10 seconds.

[0115] S608: Determine whether the fluctuation range of the current fixing temperature relative to the fixing target temperature is smaller than the first preset range. If yes, execute step S610; if no, execute step S602.

[0116] For example, the first preset range is -10°C to 10°C.

[0117] S610: Determine whether the fixing target temperature is the preset temperature; if so, execute step S602; if not, execute step S612.

[0118] For example, the preset temperature is 0°C.

[0119] S612: Determine whether the image forming device is in working state. If yes, execute step S614; if no, execute step S616.

[0120] For example, the job status is printing job status.

[0121] S614: It is determined that the image forming apparatus is in a preliminary stable state.

[0122] S616: It is determined that the image forming apparatus is not in the preliminary stable state.

[0123] In an optional embodiment, when it is determined that the image forming device is not in the preliminary stable state, the process returns to step S602 to re-determine whether the image forming device is in the preliminary stable state.

[0124] According to the method provided by the present invention, the temperature stability detection is not affected by the sudden change of the fixing target temperature caused by the image forming device changing from a non-working state to a working state, nor is it affected by the change of the fixing target temperature caused by the image forming device performing intermittent printing, thereby further improving the accuracy of the temperature stability detection.

[0125] The embodiment of the present invention provides a temperature stability detection process, such as Figure 7 As shown, the detection process includes:

[0126] S701: Monitoring the fluctuation range of the current fixing temperature relative to the fixing target temperature.

[0127] S703: When the fluctuation range of the current fixing temperature relative to the fixing target temperature is greater than a third preset range, recording the temperature instability time.

[0128] For example, the third preset range is -60°C to 60°C.

[0129] S705: When the temperature instability duration is not less than the second preset duration, outputting the temperature instability detection result.

[0130] For example, the second preset time length is 0.5 seconds.

[0131] In an optional embodiment, after the temperature instability detection result is output, temperature instability processing is performed, and the temperature instability processing method may include but is not limited to stopping heating of the image forming device, reporting a temperature instability error, and notifying the user of fixing abnormality.

[0132] According to the method provided by the present invention, when the image forming device is in a preliminary stable state, the temperature stability detection is performed on the current fixing temperature, thereby improving the accuracy of the temperature stability detection. The detection result of temperature instability is output in a timely manner, the image forming device stops heating, and notifies the user of the fixing abnormality, thereby avoiding the problem of damage to key components of the image forming device due to temperature instability.
