Streaks (2)
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, the cleaning blade of the ITB cleaning unit or transfer unit may
miss the remaining toner, causing streaks to appear sporadically.
Solution:
1. Is the printed side affected by the problem?
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.
Streaks (3)
Streaks appear in solid-filled areas.
Cause:
There are small clumps in the toner, which break down in the development unit, producing streaks.
This problem may occur if the machine was not used for a long period, or the toner bottle was left
outside its moisture barrier bag for a long period of time.
