Checking the print cartridge
Image-formation defects are frequently the result of problems in the print cartridge. If the source of the defect is not immediately evident, always replace the print cartridge before troubleshooting image defects.
Use the following checklist to make sure that the print cartridge is still operable.
? Make sure that the print cartridge is seated properly.
? Check the print cartridge to see if it has been disassembled or refilled.
? Inspect the print 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.
To redistribute the toner in the print cartridge
Before installing a new print cartridge or when the toner begins to run low, redistribute the toner by
rotating the cartridge back and forth five or six times.
