Troubleshooting
Solving print quality problems
The information in the following table may help you solve print quality problems. If these suggestions still do not correct the
problem, call for service. You may have an MFP part that requires adjustment or replacement.
Problem Action
Print is too light. • The toner may be low. To utilize the remaining toner, remove the cartridge by gripping
the handles with both hands. With the cartridge arrows pointing downward, firmly
shake the print cartridge side-to-side and front-to-back several times to redistribute the
toner. Reinstall the cartridge
. Repeat this procedure multiple times until the print
remains faded. When the print remains faded, replace the print cartridge.
• Change the Toner Darkness setting in the Quality menu.
• Change the Brightness setting in the Quality menu.
• Change the Contrast setting in the Quality menu.
• If you are printing on an uneven print surface, change the Paper Weight and Paper
Texture settings in the Paper menu.
• Verify the correct print media is being used.
• Verify you are using the correct MFP drivers.
• Verify the environment is 16 to 32 degrees C (60 to 90
o
F).
Toner smears or print comes
off the page.
• If you are printing on an uneven print surface, change the Paper Weight and Paper
Texture settings in the Paper menu.
• Verify the print media is within the MFP specifications. See Understanding paper and
specialty media guidelines for more details.
Toner appears on the back of
the printed page.

transfer roll.
Toner fog or background
shading appears on the page.
• Check the print cartridge to make sure it is installed correctly.

the Quality menu.

• Replace the print cartridge.
