Printer temperature control method and printer

Abstract

The temperature control method comprises the steps that when the printer receives a printing task, before the current printing task is executed, the number a of printed pages in first set time before the current printing task is counted, and if the interval between the current printing task and the previous printing task exceeds a preset time threshold value, the number a of the printed pages in the first set time before the current printing task is executed is calculated; if yes, a is set to be 0; whether X + a is larger than the printing page number Y or not is judged, X is the task printing page number of the current printing task, if yes, when the printer prints the front Y page, the printer is controlled to enter a temperature monitoring stage, and after the printer prints the Y page, the printer is controlled to enter a slow cooling stage; and if not, controlling the printer to enter a temperature monitoring stage. The printer has the advantages that the cooling strategy of the printer is flexibly adjusted according to the number of printed pages and the temperature condition, and therefore performance reduction or equipment damage caused by overheating of the printer can be effectively avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of printers, and in particular to a temperature control method of a laser printer and a printer. Background Art

[0002] When a printer (laser printer, thermal printer, etc.) is in use, the temperature inside the printer will continue to rise as the printing components work, which in turn causes the temperature inside the printer to continue to rise. If the high temperature state lasts too long, it will cause damage to the printer. In order to protect the printer, an alarm is required in the high temperature state and the temperature must be reduced before the printer can continue to work.

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

[0004] Although the above method can protect the printer, the above method will alarm and stop printing as long as the temperature is too high, so that the continuous printing time is limited and cannot meet the continuous printing demand for a long time. Therefore, further improvement of the prior art is needed. 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 which can meet the printing continuity and effectively avoid overheating of the printer in view of the above-mentioned prior art.

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

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

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

[0009] Determine whether X+a is greater than the number of printed pages Y, where X is the number of printed pages of the current print task. If so, when the printer prints the first Y pages, the printer is controlled to enter the temperature monitoring stage, and after the printer prints to Y pages, the printer is controlled to enter the slow cooling stage; if not, the printer is controlled to enter the temperature monitoring stage.

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

[0011] During the printing process, the printer detects the temperature once for each page printed. If the detected temperature is greater than the temperature threshold, the printer immediately enters the cooling mode and continues to execute the printing task after the cooling time reaches the second set time.

[0012] Preferably, the printer enters a slow cooling stage, specifically:

[0013] The printer pauses printing for a third set time, and after the third set time expires, the printer is allowed to print a set number of pages of paper, and after the printer prints the set number of pages of paper, the printer is controlled to enter a temperature monitoring phase.

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

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

[0016] Furthermore, if the printing error is not resolved, the printer remains in a paused state; if the printing error is resolved, the printing task continues to be executed.

[0017] Furthermore, if the printer pause time exceeds a fourth set time, the number of printed pages is reset to zero, and it is determined again whether the number of printed pages is greater than Y.

[0018] After the printing task is completed, the number of printed pages is reset to zero and the printer receives new printing tasks again.

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

[0020] Compared with the prior art, the advantages of the present invention are: by flexibly adjusting the cooling strategy of the printer according to the number of printed pages and temperature conditions, it is possible to effectively avoid overheating of the printer and resulting in performance degradation or equipment damage; in addition, by setting a slow cooling stage, while ensuring the safety of the printer, it also ensures the continuity and integrity of the printing task, thereby maximizing printing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 4 is a flow chart of a temperature control method for a printer in an embodiment of the present invention. DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings.

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

[0024] Determine whether X+a is greater than the number of printed pages Y, where X is the number of printed pages of the current print task. If so, when the printer prints the first Y pages, the printer is controlled to enter the temperature monitoring stage, and after the printer prints to Y pages, the printer is controlled to enter the slow cooling stage; if not, the printer is controlled to enter the temperature monitoring stage.

[0025] The printer enters the temperature monitoring stage, specifically:

[0026] During the printing process of the printer, the temperature is detected once for each page printed. If the temperature detected is greater than the temperature threshold, the printer immediately enters the cooling mode, and continues to execute the printing task after the cooling time reaches the second set time. In this embodiment, a temperature sensor is set in the printer to detect the temperature through the temperature sensor;

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

[0028] The printer pauses printing for a third set time, and after the third set time expires, the printer is allowed to print a set number of pages of paper, and after the printer prints the set number of pages of paper, the printer is controlled to enter a temperature monitoring phase.

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

[0030] During the printing process, if the printer pauses printing due to an error for a period of time exceeding the fourth set time, a paper jam or paper shortage detection is performed. In this embodiment, the fourth set time is 600 seconds; during the printing process, if a paper jam or paper shortage error is detected, the printer will pause printing. In addition, if the printing error is not resolved, the printer remains in the pause state; if the printer pause time exceeds the fourth set time, the current number of printed pages is cleared, and it is re-determined whether the number of printed pages is greater than Y; if the printing error is resolved, the printing task continues to be executed.

[0031] After the printing task is completed, the number of printed pages is reset to zero and the printer receives new printing tasks again.

[0032] This embodiment also relates to a printer, which is applied with the temperature control method as described above.

[0033] In this embodiment, during the printing process of the printer, the temperature is detected once each time a page is printed. Under normal circumstances, the temperature will not reach 60°C; if the temperature reaches 60°C, it will be cooled directly for 10 minutes. This is to prevent the user from unplugging the power and then printing continuously again immediately; and by setting a slow cooling stage, while ensuring the safety of the equipment, the continuity and integrity of the printing task are also ensured.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
