Chapter 13
Description
This symptom can also be caused by combined factors; in other words, the resistance of the intermediate transfer belt
and the amount of deposited toner may well be within allowance individually, they can trigger the symptom when
combined. Improvements have been made so that the level of the symptom is equal to that found in past machines;
if the user points it out, however, provide the foregoing remedy. The fault, however, is of a negligible level.
