What should I do if the image printed by the printer has obvious ghosting?

1. Reason: The ghosting may be caused by the quality problems of paper and toner and the failure of transfer roller.

Second, maintenance methods:

Step 1. Replace the original toner and high-quality printing paper, and the test found that the fault still exists.

step 2. turn on the printer and check the transfer roller, and it is found that there is a lot of toner on the transfer roller.

step 3. after removing the toner on the transfer roller, it is found that the surface of the transfer roller is seriously worn.

step 4. replace the transfer roller with a new one and test it again. it is found that the phenomenon of ghost does not appear again.

the solution of ghosting in laser printer

1. Transfer printing link

The transfer printing in laser printer refers to the process that the carbon number of electrostatic latent image formed on the drum core is transferred from the drum core to the paper under high transfer pressure. If the transfer fails (for example, the transfer voltage is wrong), the toner will not be completely transferred to the paper. With the rotation of the drum core, the image part of this electrostatic latent image will also be transferred to the paper in the next cycle, which will cause the phenomenon of ghosting in the laser printer.

Solution:

① Clean the toner and use special toner (if you use the wrong toner, it will lead to ghosting of the printer due to the charged toner) ② Reset the paper type (when the paper is set as thick paper or film, the transfer voltage will be higher than that of ordinary paper).

③ check whether both ends of the transfer roller are in good condition and whether the transfer is normal.

2. Fixing link

Fixing refers to that the toner on the paper is hot pressed into the paper fiber at high temperature, so that the toner is bound to the paper and will not fall off. If the toner sticks to the fixing, it will print periodic ghosting on the paper with the rotation of the fixing, which will also cause what we call the printer ghosting problem.

Solution:

① The melting point of toner is too low and it is easy to stick to the hot roller. Clean the toner and use special toner.

② The material of the fuser hot roller is not good, or it is aging. Replace the fuser hot roller with good quality.
