Cleaning and Maintenance
Belts: There are 3 rubber belts in the printer. Inspect the belts for wear.
Look for these problems:
■ Loose rubber particles below the belts indicate a worn belt.
■ Missing teeth in the belts
■ Cracking or moderate fraying; a small amount of fraying is inevitable, so
look for other signs of wear before replacing the belt.
