Description

Technical Field

[0001] This invention relates to the field of printer technology, and more particularly to a temperature control method for a laser printer and the printer itself. Background Technology

[0002] When a printer (laser printer, thermal printer, etc.) is in use, the internal temperature of the machine will continuously rise as the printing components work, leading to a sustained increase in internal temperature. If this high temperature persists for too long, it can damage the printer. To protect the printer, it needs to trigger an alarm and cool down in case of high temperature before allowing it to continue operating.

[0003] For example, Chinese invention patent ZL202210410853.7 (authorization announcement number CN114851715B) discloses a thermal printer temperature alarm method. Based on the principle that heat and temperature can be converted into each other in physics, the temperature of the printer cartridge is represented in the form of heat. When the heat value reaches the maximum allowable heat value of the printer cartridge, an alarm is triggered and printing is stopped to protect the printer cartridge.

[0004] While the above methods can protect the printer, they also limit the continuous printing time due to the alarm and printing halt caused by overheating. This does not meet the needs of extended continuous printing. Therefore, further improvements to the existing technology are necessary. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a temperature control method for a printer that can meet the requirements of continuous printing and effectively avoid overheating, in contrast to the above-mentioned prior art.

[0006] The second technical problem to be solved by the present invention is to provide a printer that applies the above-mentioned temperature control method.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a temperature control method for a printer, characterized by comprising:

[0008] When the printer receives a print job, before executing the current print job, it counts the number of pages printed 'a' within a first set time period before the current print job. If the interval between the current print job and the previous print job exceeds a preset time threshold, then 'a' is set to 0.

[0009] Determine if X+a is greater than the number of pages to be printed, Y, where X is the number of pages to be printed in the current print job. If yes, control the printer to enter the temperature monitoring stage when the printer has printed the first Y pages, and control the printer to enter the slow cooling stage after printing Y pages. If no, control the printer to enter the temperature monitoring stage.

[0010] Preferably, the printer enters the temperature monitoring stage, specifically as follows:

[0011] During the printing process, the temperature is checked after each page is printed. If the temperature is found to be higher than the temperature threshold, the printer immediately enters the cooling mode. After the cooling time reaches the second set time, the printing task continues.

[0012] Preferably, the printer enters a slow cooling phase, specifically as follows:

[0013] The printer pauses printing for the third set time. After the third set time has elapsed, the printer is allowed to print the set number of pages. After the printer has printed the set number of pages, the printer is controlled to enter the temperature monitoring stage.

[0014] To improve the reliability and stability of the printer, if the printer pauses printing for more than the fourth set time due to an error during the printing process, a paper jam or paper shortage detection will be performed.

[0015] Furthermore, if a paper jam or paper shortage error is detected during the printing process, the printer will pause printing.

[0016] Furthermore, if the printing error is not resolved, the printer remains paused; if the printing error is resolved, the printing task continues.

[0017] Furthermore, if the printer pauses for longer than the fourth set time, the number of pages printed will be reset to zero, and the printer will re-evaluate whether the number of pages printed is greater than Y.

[0018] After the print job is completed, the number of printed pages is reset to zero, and the printer will then accept new print jobs.

[0019] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a printer, characterized in that: it applies the temperature control method of the printer as described above.

[0020] Compared with the prior art, the advantages of the present invention are: by flexibly adjusting the printer's cooling strategy according to the number of pages printed and the temperature, the printer can be effectively prevented from overheating and causing performance degradation or equipment damage; in addition, by setting a slow cooling stage, the continuity and integrity of printing tasks are ensured while ensuring printer safety, thereby maximizing printing efficiency. Attached Figure Description

[0021] Figure 1 This is a flowchart of the printer temperature control method in an embodiment of the present invention. Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, the temperature control method of the printer in this embodiment includes: when the printer receives a print job, before executing the current print job, counting the number of pages 'a' printed within a first set time period before the current print job; if the interval between the current print job and the previous print job exceeds a preset time threshold, then setting 'a' to 0.

[0024] Determine if X+a is greater than the number of pages to be printed, Y, where X is the number of pages to be printed in the current print job. If yes, control the printer to enter the temperature monitoring stage when the printer has printed the first Y pages, and control the printer to enter the slow cooling stage after printing Y pages. If no, control the printer to enter the temperature monitoring stage.

[0025] The printer enters the temperature monitoring phase, specifically as follows:

[0026] During the printing process, the temperature is checked after each page is printed. If the detected temperature exceeds a certain threshold, the printer immediately enters a cooling mode. After a second set cooling time, the printing task continues. In this embodiment, a temperature sensor is installed inside the printer to detect the temperature.

[0027] The printer enters a slow cooling phase, specifically:

[0028] The printer pauses printing for the third set time. After the third set time has elapsed, the printer is allowed to print the set number of pages. After the printer has printed the set number of pages, the printer is controlled to enter the temperature monitoring stage.

[0029] In this embodiment, the first set time is 480 seconds, the preset time threshold is 600 seconds, the number of pages to be printed is Y=165, the temperature threshold is 60℃, the second set time is 600 seconds, the third set time is 90 seconds, and the set number of pages is 5. The above values ​​can be empirical values ​​or confirmed based on actual printing tests.

[0030] During printing, if the printer pauses printing for more than a fourth preset time due to an error, a paper jam or paper shortage detection will be performed. In this embodiment, the fourth preset time is 600 seconds. If a paper jam or paper shortage error is detected during printing, the printer will pause printing. Furthermore, if the printing error is not resolved, the printer remains paused. If the printer pause time exceeds the fourth preset time, the number of pages printed is reset to zero, and the printer re-evaluates whether the number of pages printed is greater than Y. If the printing error is resolved, the printing task continues.

[0031] After the print job is completed, the number of printed pages is reset to zero, and the printer will then accept new print jobs.

[0032] This embodiment also relates to a printer that uses the temperature control method described above.

[0033] In this embodiment, the temperature is checked after each page is printed during the printing process. Under normal circumstances, the temperature will not reach 60°C. If the temperature reaches 60°C, it will be cooled for 10 minutes. This is to prevent users from unplugging the power and printing again immediately after continuous printing. By setting a slow cooling stage, the continuity and integrity of the printing task are ensured while ensuring the safety of the equipment.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
