Checking the print cartridge
Image formation defects are frequently the result of problems in the
print cartridge. If there is any doubt, 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.
 Inspect the print cartridge for toner level.
 Check the expiration date stamped on the print cartridge box.
 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.
Note A print cartridge weighs approximately 863 gm. (30.5 oz.) when it
is full, approximately 766 gm. (27.0 oz.) when it first fades, and
approximately 742 gm. (26.2 oz.) when it is empty.
To redistribute toner in the print cartridge
Before installing a new print cartridge or when toner begins to run
low, redistribute the toner by rotating the cartridge back and forth five
or six times.
