Maintenance Procedures
Clean other components as needed
Dirt and 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 — Three 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 blade 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.
• Scanner platen — The scanner platen is located on the
underside of the scanner cover.
• Scanner rollers and ADF pad — The scanner rollers and
the ADF pad are part of the automatic document feeder
inside the scanner.
Use the following procedure to clean the additional components:
1. Push the printer cover release button to open the printer
cover.
WARNING
Do not touch the heater unit inside the
machine. The heater unit is extremely hot while
the machine is operating.
