Marks on Paper Service Check
If you have evenly spaced marks on the paper, measure the
distance between the marks and locate the symptom below. 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 will cause lower transfer efficiency and washed
out colors.
