Laser printer maintenance environment

Laser printer is our most commonly used office equipment. Because of its light sets, electric, mechanical and other components in one complex structure, it is necessary to make laser printers work in a standard to meet the requirements of the environment.

Humidity requirements
Laser printers work in high humidity environment, the air in the water tended to agglutinate in the components of the surface. The result is a much greater decline in electrical insulation, severe short-circuit will cause the circuit part of the phenomenon of burning the printer. In addition, the air humidity is too large will seriously affect the laser printing is very likely to charge, transfer electrode to short circuit, to print all white goods.

If the humidity is too low, will cause the static, particularly in the nylon fiber fabric is more serious. Electrostatic hazards is the low voltage integrated circuits to the breakdown, a small static data transmission will be pushed to the correctness of impact. Practice shows that the relative humidity range of 20% to 60%, more suitable for laser printers work.

Temperature
Experiments show that when the temperature exceeds 25 ¡æ, the temperature of each rise 10 ¡æ, 25% decline in circuit reliability. At the same time as RC components vary with temperature and, to a certain extent, will cause waveform distortion when the data transfer. Resulting in data errors. Magnetic media at high temperatures also have a data loss situation.

Mechanical moving parts of a laser printer in the temperature change is large, but not working because of thermal expansion and contraction, resulting in shortened life expectancy in the relevant parts, or even cards death can not be completed print job. Based on actual experience temperature should be maintained at 10 ¡æ ~ 35 ¡æ within.

Other Requirements
1. With electrical appliances, laser printers on the power supply voltage requirements more stringent, excessive voltage fluctuations would cause serious harm laser printers, fluctuations should not exceed 10% range (between about 190V ~ 230V).

2. Laser printers should not be exposed to the sun. Directly affected by sunlight, the shell will make a laser printer and some parts of accelerated aging.

3. Room should be kept well ventilated. As the laser printer at work will generate a lot of heat; should make timely distribution of these calories off, otherwise it will lead to a laser printer does not work because of overheating.

4. Laser printers should not be close to the walls and other objects, leave at least 20cm distance, but also to maintain the level of the printer's display, the installation firm.

5. Laser printers have a good grounding in general does not allow use of single-phase two-wire system of distribution method to the laser printer supply, use separate lines for its power supply. This is because without a good grounding in the laser printer prone to static electricity, and static electricity are easily damaged laser printer parts, while the machine is easy when high-pressure part of the leakage caused by electric shock.
