Toner contamination
• Toner
contamination is
visible at regular
intervals on the
printout.
•
Toner
contamination is
visible at random
intervals over the
whole or parts of
the printout.
1. Contamination at regular intervals:
•
A) Check the distance between
contamination marks.

cartridge OPC drum. If both ends are
contaminated with toner, the waste
toner collector is full.

points of the toner cartridge are
clean. Clean all HV contacts if they
are dirty. Replace the toner cartridge

points of the toner cartridge are not
damaged. Replace the toner cartridge
if there is damage to the contact
terminals.
