A printer is a device that prints a computer's calculation results or intermediate results on a paper in a predetermined format by numbers, letters, symbols, and graphics that can be recognized by humans. The printer is moving toward light, thin, short, small, low power, high speed and intelligent. So, what are the common faults and tips for HP a3 laser printers? Let me introduce them to you.
First, the HP a3 laser printer should pay attention to the following points in use:
1. The printer case must have a good grounding conductor. Otherwise, static electricity generated by the printer may cause the performance of the machine to be unstable, affecting the quality of the sample, and in severe cases, it may damage the machine and injure people.
2. The printer has more high voltage and higher temperature, so you can't open the case.
3, the power of this machine is large, the frequency of temperature control thyristor is high, it is best to use a single regulated power supply.
4. When a paper jam occurs during use. Be sure to identify the jammed area first, then gently and effortlessly remove the jammed paper. Otherwise, it will damage the relevant parts or paper scraps left in the machine to affect the quality of the sample.
5, printer paper, the minimum can not be less than 52g / square meter, the maximum can not exceed 130g / square meter, it is best to use offset paper or copy paper. Coated paper can not be used in laser printers, mainly because the heating and setting process during the printing process causes the copper plate to foam and affect the use.
6. After the printer is finished, it is very important to maintain the cleaning work. Special attention should be paid to the cleaning of the optical part. The metal tool cannot touch the drum core to avoid permanent damage. In the cleaning, pay attention to the laser is invisible, pay attention to protect the eyes.
7. Users can replace the toner cartridge core regularly and refill the toner according to the production needs. The toner cartridge can be used multiple times; or simply clean it to obtain high-quality text and graphics.
Second, the correct and timely maintenance and maintenance of the HP a3 laser printer can eliminate many failures.
The toner cartridge of a laser printer is also called a "printing box", and its consumption is based on the number of pages - theoretically, a brand new toner cartridge can print about 3,500 pages. As for how much can be printed in actual use. The page depends on the content of the print and the concentration used, but the toner is not as volatile as the ink and the waste caused by the cleaning, so it is still very suitable for mass printing of high-quality documents.
The toner cartridge contains a photosensitive drum and a certain amount of toner - the photosensitive drum is used to receive the laser beam and generate electrons to attract the toner and reprint it on the surface of the paper. If the toner on the printed job page is biased If it is light, then we can extend the toner cartridge by gently swaying the toner cartridge a few times to redistribute the toner. If the print does not come out, the toner may have been used up. Now, we need to replace the entire toner cartridge.
The above is a description of the common faults and tips of HP a3 laser printers, I hope everyone can help.
