Determine the Cause of Streaky Printouts

Especially as a layman, it is sometimes difficult to determine the cause of the “laser printer prints stripes” problem. We therefore recommend making several test prints. Although you use toner and paper in the process, you can better isolate the origins of the error.

If the printouts get lighter and the stripes clearer from time to time , then it is usually due to a defective or empty toner. Therefore, replace this consumable or shake it briefly. If, on the other hand , the toner can be smudged directly on the paper after printing , there is usually a fault in the fuser unit.
You should also pay attention to whether the stripes always appear in the same place or whether this varies. If the toner powder cannot be wiped away and the streaks are always in the same place , there is often a fault with the image drum.

    If in doubt, you can simply reset the settings to “default”. This way you can be sure that the printer settings are not the reason why your laser printer is printing streaks.
  2. Toners
    Often times the toner runs out and you need to replace the cartridge. However, check that the toner is actually empty by removing the cartridge from the laser printer and shaking it a few times to loosen any remaining toner powder.

    Some printer models also offer cleaning via software. This can definitely help with very fine strips. If the strips cannot be removed with cleaning, the only thing that ultimately helps is to replace them.
  4. Fuser unit
    The fuser is another source of error. If this is defective or dirty , the toner powder can no longer adhere properly. If the stripe print is very consistent, this indicates a fault with the fuser.
    Cleaning is recommended in many cases. Otherwise the only solution is to replace the fuser unit.
  5. Cleaning
    It is always a good solution when cleaning your laser printer to help the longevity of your device . This also applies if you want to improve the print quality. Proceed with extreme caution, however, as the laser printer is very sensitive.
    It is best to use a special toner vacuum cleaner , which is perfectly adapted to the very fine powder. Otherwise, brushes, cotton swabs and cold water are also suitable for coarse soiling, as well as lint-free cloths (kitchen paper).
