Vertical Black (color) Streaks (2)
Extended, blurred black (color) 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 paper transfer unit, causing streaks to appear sporadically.
Solution:
1. To identify the affected color, print three full-page, solid-fill A3 or DLT sheets for each of
cyan, yellow, magenta, and black.
