Ensure that the toner cartridge is seated properly.
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.
