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 check list to ensure that the toner cartridge is still operable.
l Ensure that the toner cartridge is seated properly in the cavity.
l Inspect the toner cartridge for remaining toner.
l Check the expiration date of the toner cartridge (stamped on the cartridge box).
l Check the toner cartridge to see if it has been disassembled or refilled.
Note The full weight of the toner cartridge is 26.1 oz (730 grams), and its empty weight is 22.7 oz. (640
grams).
l Inspect the cartridge for leaking toner through worn seals. (If the drum has been manually
rotated it may have caused internal damage and toner spills may result).
l Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or
scratched. Touching the drum will contaminate the photosensitive surface and may cause
spotting and defects during printing.
l Blurred areas on the page may indicate that the drum has been exposed to light for too long. This
causes permanent damage to the photosensitive drum. Replace the cartridge.
