• 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.)
Belts: Inspect the belts for wear. There are eight rubber belts in the
printer:
• A belt from the process motor to the compound gear
• Two belts from the y-axis motor drive
• A belt from the lower paper feed roller to the upper paper feed
roller
• Two belts on the cap/wipe/purge drive
• An exit roller drive belt
• A small belt for driving the cap/wipe purge assembly from the
cap/wipe/purge clutch
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.
Clutches: There are four clutches: the paper-pick roller clutch, the
upper feed roller clutch, the maintenance drawer cam clutch and the
cap/wipe/purge clutch. Symptoms of a malfunctioning clutch are the
printer not picking paper from the tray or other paper jams. Also the
cap/wipe/purge system could fail. In such cases, replace the clutch.
