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.
•• Ensure that the toner cartridge is seated properly in the cavity.
•• Inspect the toner cartridge for remaining toner.
•• Check the expiration date of the toner cartridge (stamped on the cartridge box).
•• Check the toner cartridge to see if it has been disassembled or refilled.
Note
The toner cartridge’s full weight is 26.1 oz (730 grams), and its empty weight is
22.7 oz. (640 grams).
•• 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).
•• 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.
•• White areas on the page may indicate that the drum has been exposed to light for
too long. If white areas appear, stop the printer and wait a few minutes. This
process should eliminate most defective images. If not, the toner cartridge may be
placed in a dark environment for several days, which may restore some life to the
drum.
