Frequent, Reoccurring Offset
Toner accumulates on the fusing roller, abnormal Image Condition (drop in density, defective drum cl
eaning,
defective transfer cleaning, etc...).
Action:
•
Was the total number of copies made while the machine was in use extremely high or low?
•
Is the toner a Ricoh product?
•
Is the hot roller a Ricoh product?
•
Is the pressure roller a Ricoh product?
•
Some types of paper may be the cause of the reoccurring offset problems.
ADDITIONAL INFORMATION
Phenomena mistaken for Offset
1. The offset drawings and characters are inverted (aligned with the image on the back of the original)
Cause: Back of the original was copied.
2. The offset pitch is 188.5mm
Cause: A scratched drum. Replace the drum.
3. Irregular Occurrences, Fused Image
Cause: Defective drum cleaning. Confirm that the parts around the drum are functioning properly
(cleaning blade, etc...).
4. Images on the surface unrelated to the original; lines appear parallel to the paper feed direction.
Cause: Defective drum cleaning, scratched drum and/or uneven lighting from the exposure lamp.
Inspect the parts around the drum (cleaning blade, etc...). Check for uneven exposure lamp
illumination.
5. Lines appear on the back of the copy parallel to the paper feed direction.
Cause: Defective transfer belt cleaning and/or toner scattering in the machine
Check the transfer unit and transfer unit cleaning blade. Because toner scattering may occur when
the toner density is too high, the Process Control Conditions should be checked.
