5. Troubleshooting
• The problem is more likely to occur with a wrinkled ITB because the distance between the ITB
and drum could come closer at the wrinkled spots, resulting in the discharge. The unwanted
lines usually appear interrupted in this case.
• Also, the problem is more likely to occur with brand new units. Running the machine will
acclimatize the ITB and drum, and resolve the problem.
This diagram describes the condition of the ITB and drums when the ITB is in contact with all the
drums.
However, when the ITB retracts from the color drums, the distance between the ITB and Y, M and C
drums varies. The C drum is closest to the ITB.
Solution
For solid lines:
Replace the ITB drive roller.
If the problem persists even after replacing the ITB driver roller, print out 10 to 50 copies of solid
images in 100% Cyan to acclimatize the ITB and drum.
For interrupted lines:
Replace the ITB driver roller. This will help prevent wrinkles from forming on the ITB.
