Why do vertical streaks appear in printing

1. The cleaning blade is notched or the photosensitive drum has obvious scratches

If the cleaning blade is notched or the photosensitive drum has obvious scratches, it means that these two parts have been damaged. At this time, the cleaning blade or the photosensitive drum needs to be replaced to solve the problem.

2. The powder knife is aging

Every item has a service life, the same as the powder knife. When the powder knife is aging, vertical streaks will appear. At this time, you need to replace the powder knife to solve the problem.

3. The corona wire or charging roller is contaminated

If the corona wire or the charging roller is contaminated, vertical stripes will be printed. But it doesn't matter, just clean the corona wire or the charging roller to solve the problem.

4. Defective fixing roller

Check the fixing roller to see if it is damaged or defective. If it is a problem with the fixing roller, just replace it.

5. Too much toner accumulates on the magnetic roller

Too much toner accumulates on the magnet roller, which will affect the printing effect. You can gently shake the toner inside the drum and try printing a few more pages to see if the problem can be solved.
