■ Loss of traction (tackiness) causing pick or feed failures
Gears: Replace gears that show any signs of wear or breakage. Look for these
problems:
■ Thinned gear teeth
■ Bent or missing gear teeth; check especially where a metal gear drives a
plastic gear.
■ Fractured or cracked gears (Oil or incorrect grease on a plastic gear can
cause the gear to crack.)

■ Y-axis belt that rotates the drum
■ Two small belts for the exit module, exit rollers (rotation and lift)

Inspect the belts for wear and look for these problems:
■ Loose rubber particles below the belts indicate a worn belt.
■ Missing teeth in the belts
■ Cracking or moderate fraying is inevitable, so look for other signs of wear
before replacing the belt.
