Description
If thick paper (particularly, coated paper) is used on machines manufactured in the early stage of production (old
type of the delivery vertical path ass'y is installed), there might occur a difference in gloss between the area where
the delivery rollers come in contact and the other area, when the paper passes through the rollers, depending on
the paper in use and the toner duty of the original document.
Field Remedy
1. Replace the three parts listed below with a new one respectively.
2. In service mode (Level 2) [COPIER> Option> BODY> CTM-MARK], change the set value to "1".
Note: As a result of the setting change above, the paper delivery speed when the delivery vertical path ass'y is used
will be changed and thus the productivity might be affected. Therefore, be sure not to change it if the machine
operates normally.
