What is the function of a laser printer? How to solve the problem of blurry printing on a laser printer?

Laser printers can scan and copy documents, and transmit data to a print server via the network. They are generally used in office environments. Relatively speaking, more families use inkjet printers because they are economical. Today, let’s learn about the role of laser printers and how to solve the problem of fuzzy printing with laser printers. Let’s learn about it together!

The role of laser printers

The functions of a laser printer: it can scan and copy documents, transmit data to a print server via the network to achieve network printing, perform automatic double-sided printing without manual operation by the user, print important meeting documents, print brochures or product manuals, and print multiple copies of receipts, pictures and photos.

How to solve the problem of blurry printing on laser printer

reason:

The printing paper is incompatible with the printer, there is a problem with the photosensitive drum in the toner cartridge assembly, the lens and reflector in the laser scanning system are contaminated, there is a problem with the laser generator, the transfer roller in the transfer separation system is contaminated, the voltage is abnormal, and the heating roller in the fixing system is contaminated.

Solution:

1. Replace the printing paper on the table. After replacement, the fault still exists.

2. Print a test page, cut off the power of the printer in the middle of printing, observe the image on the surface of the photosensitive drum, and find that there is a problem with the latent image of the photosensitive drum.

3. Open the toner cartridge and check the high-pressure roller connected to the toner cartridge. The high-pressure roller is normal.

4. Check the laser scanning system and find that the lenses, reflectors, etc. in the laser scanning system are contaminated.

5. Clean several reflective surfaces of the prism and other reflectors, then print a test page to troubleshoot the problem.

How to deal with ghosting when printing with a laser printer

1. Use better quality paper and print again to see if the ghost image still exists.

2. If ghosting still occurs, confirm whether the toner in the toner cartridge is genuine original toner.

3. If ghosting still occurs when using high-quality printing paper and original toner, the surface of the laser printer's heating component may be damaged, and toner may stick to the heating component, causing ghosting. The product needs to be sent to after-sales service for inspection and repair.
