Cleaning the Components as Needed
Dirt or dust gather in the machine and can cause the machine to print
incorrectly. The following lists the parts to clean and how the dirt can
affect the print quality.
•
Contacts— These groups of contacts are located under the
Developer Assembly. Dirt or dust on the contacts causes the
printer to blur characters.
•
Metering Blade— The Metering Bade is located above the black
toner roller on the Developer Assembly. Dirt between the magnet
roller and the metering blade causes the machine to print vertical
lines.
•
Document Scanner— The Document Scanner is located on the
underside of the Control Panel.
•
Scanner Rollers and Retard Pad— The Scanner Rollers and
the Retard Pad are parts of the automatic document feeder inside
the scanner.
