Marks on paper service check
If you have evenly spaced marks on the paper, measure the distance between the marks, and locate the
symptom in the following table. Check the assembly for dirt or damage and clean as necessary. Run a test print
to verify the problem has been corrected. The indicated assemblies are replaced by the customer at prescribed
intervals.
If you remove the transfer belt, do not turn it upside down. Toner will fall from the waste toner box onto the
transfer sheets and roller(s) inside the belt. This causes lower transfer efficiency and washed out colors.
