Check the memory chip for damage.

 

Examine the surface of the imaging drum on

the bottom of the toner cartridge.

Do not touch the roller (imaging

drum) on the bottom of the cartridge.

Fingerprints on the imaging drum can cause

print-quality problems.

 

If you see any scratches, fingerprints, or other

damage on the imaging drum, replace the

toner cartridge.

 

If the imaging drum does not appear to be

damaged, rock the toner cartridge gently

several times and reinstall it. Print a few pages

to see if the problem has resolved.

 

Use different paper if you are having any of the following problems:

●

The printing is too light or seems faded in areas.

●

Specks of toner are on the printed pages.

●

Toner is smearing on the printed pages.
