Image Deformation, Scratches, Streaks, Paper Creases or Bent Corners
Cause:
• The paper exit roller is stained.
• The line speed of the exit motor or the paper feed speed at the switchback entrance/exit is too fast
or too slow.
• The paper feed speed is too fast or too slow for the decurler unit operation.
• The decurling direction or strength of the decurler unit is not specified correctly.
Solution: (Adjust the line speed of the paper exit motor and the paper feed speed at
the switchback entrance/exit)
If the problem persists even after the paper exit roller is cleaned, adjust the line speed of the paper exit
motor and the paper feed speed at the switchback entrance/exit.
