Extended, blurred streaks parallel to the paper feed direction appear. The streaks also appear randomly in the margins.

Cause:

If the temperature or humidity is low, remaining toner might be missed by the cleaning blade of the ITB cleaning unit or transfer unit, causing streaks to appear sporadically.

Solution:

  1. Is the printed side affected by the problem?

    Yes

    Go to the next step.

    No

    Consult the product specialist.

  2. Replace the ITB cleaning unit.
  3. If the problem persists after you have replaced the ITB cleaning unit, consult the product specialist.
