Laser Printer is the most commonly used office equipment. Because it sets optical, and mechanical components such as integrated, complex structures, it is necessary to make laser printers work in a standard to meet the requirements of the environment.
Humidity requirements
Laser printers in the high humidity environment work, the moisture in the air easily lectin in the components surface. The result is a substantial reduction in the degree of electrical insulation, will be a serious part of a short circuit caused the phenomenon and burned printers. In addition, excessive humidity in the air will be seriously affected laser printing results at 160 million charge, Transfer Printing electrode on the short circuit, so that the whole white print materials.
If the humidity is too low, it will entail the formation of static electricity, especially in the chemical fiber nylon fabrics even more serious. The harm is to make static pressure is not high by the breakdown of integrated circuits, electrostatic minor data transmission will be pushed to do about the impact of. Practice shows that the relative humidity of 20% ~ 60%, more suitable for laser printers work.
Temperature effects
Results show that, when the temperature exceeds 25 ° C, the temperature increased 10 ℃ every circuit reliability dropped 25%. At the same time as the resistive and capacitive components parameters with temperature changes, to a certain extent, will cause the waveform data transmission distortion. Resulting data errors. Magnetic medium high temperature will produce data loss phenomenon.
Laser printers mechanical moving parts in larger temperature changes, due to d dysfunctional, resulting in shortened life expectancy related components, and even print cards unable to complete the work. Based on actual experience temperature should be maintained at 10 ° C to 35 ° C within.
Other requirements
1. As with appliances, laser printers on the supply voltage requirements more stringent, excessive fluctuations in the voltage will cause serious harm laser printers, the fluctuations should be not more than 10% (about 190 V ~ 230V between).
2. Laser printers should not be exposed to the sun. The direct sunlight exposure, laser printers will shell and some parts of accelerated aging.
3. Good indoor ventilation should be maintained. As laser printers at work will produce a lot of heat; These calories should enable timely dissemination swap, otherwise this will lead to laser printers because of overheating and not working.
4. Laser printers should not be close to the walls and other objects, at least 20 cm distance, and the placing of the printer to maintain standards, installation firm.
5. Laser printers have a good grounding, the general does not allow the use of single-phase two-wire approach to the distribution of laser printers electricity, should use separate lines of its electricity. This is because without a good grounding in laser printers easily static, and static electricity are easily damaged laser printer components, while some high voltage leakage inside the aircraft also easily lead to electric shock accident.
