Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See the table below to clear the problem.

 

CONDITION

SUGGESTED SOLUTIONS

 

 

Light or faded print If a vertical white streak or faded area appears on

 

 

the page:

 

 

The toner supply is low. You may be able to temporarily extend the toner cartridge life. See

page 60. If this does not improve the print quality, install a new toner cartridge.

The paper may not meet paper specifications; for example, the paper is too moist or too

rough. See page 30.

• If the entire page is light, the print resolution setting is too low. Adjust the print resolution. See the help screen of the printer driver.

A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning.

The surface of the LSU part inside the machine may be dirty. Clean the LSU, contact a service representative.

Dropouts

If faded areas, generally rounded, occur randomly

 

on the page:

reprinting the job.

• The moisture content of the paper is uneven or

the paper has moist spots on its surface. Try a

different brand of paper. See page 30.

• The paper lot is bad. The manufacturing

AaBbCc

processes can cause some areas to reject

 

toner. Try a different kind or brand of paper.

Change the printer option and try again. Go to printer properties, click Paper tab, and set type to Thick Paper. Refer to the Software section for details.

If these steps do not correct the problem, contact a service representative.

White Spots

White spots appear on the page:

The paper is too rough and a lot of dirt from the

paper falls to the inner devices within the machine, which means the transfer belt may be dirty. Clean the inside of your machine. Contact a service representative.

• The paper path may need cleaning. Contact a service representative.

Vertical lines

If black vertical streaks appear on the page:

The drum inside the toner cartridge has probably been scratched. Remove the toner cartridge and install a new one. See page 60.

If white vertical streaks appear on the page:

• The surface of the LSU part inside the machine may be dirty. Clean the LSU, contact a service representative.

Color or Black

If the amount of background shading becomes

background

unacceptable:

Change to a lighter weight paper. See page 30.

Check the machine’s environment: very dry (low humidity) or high humidity (higher than

80% RH) conditions can increase the amount of background shading.

Remove the old toner cartridge and install a new one. See page 60.

Toner smear

Clean the inside of the machine. See page 57.

 

• Check the paper type and quality. See page 30.

 

Remove the toner cartridge and install a new

 

 

one. See page 60.
