Image formation troubleshooting
Check the toner cartridge
Image formation defects are many times the result of toner cartridge
problems. If there is any doubt, always replace the toner cartridge
before troubleshooting image defects.
Use the following checklist to ensure that the toner cartridge is still
operable.
Ensure that the toner cartridge is seated properly in place.
Inspect the toner cartridge for remaining toner.
Check the expiration date stamped on the toner cartridge box.
Check the toner cartridge to see if it has been disassembled or
refilled.
Inspect the cartridge to see if toner is leaking through worn seals.
Check the surface of the photosensitive drum in the cartridge to
see if it has been damaged or scratched. Touching the drum
contaminates the photosensitive surface and can cause spotting
and image defects.
Blurred areas on printed pages indicate that the photosensitive
drum in the cartridge has been overexposed to light. Because
overexposure to light causes permanent damage to the
photosensitive drum, the cartridge should be replaced.
Note
A toner cartridge weighs 730 grams (26.1 ounces) when it is full and
640 grams (22.7 ounces) when it is empty.
To redistribute toner in the cartridge
Before installing a new cartridge, or when toner begins to run low,
redistribute the toner by rotating the cartridge back and forth five or
six times.
