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

• The paper may not meet paper specifications; for example, the paper may be too moist or rough. (Page 4.3)

If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print resolution and turn the toner save mode off. See the help screen of the printer driver and refer to Software section, respectively.

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

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

Toner specks

The paper may not meet specifications; for

 

 

example, the paper may be too moist or

 

 

rough. (Page 4.3)

 

The transfer roller may be dirty. Clean the

 

 

inside of your machine. Contact a service

 

 

representative.

 

The paper path may need cleaning. Contact

 

 

a service representative.

Dropouts

If faded areas, generally rounded, occur

 

randomly on the page:

• A single sheet of paper may be defective. Try 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. (Page 4.3)

• The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or brand of paper.

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

Suggested solutions

White Spots

White spots appears on the page:

 

The paper is too rough and a lot of dirt from

 

 

a paper falls to the inner devices within the

 

 

machine, so the transfer roller may be dirty.

 

 

Clean the inside of your machine.

The paper path may need cleaning. Contact

 

 

a service representative.

Vertical lines

If black vertical streaks appear on the page:

 

The drum inside the printer has probably

 

 

been scratched. Remove the drum cartridge

 

 

and install a new one. (Page 10.4)

 

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.

Gray background

If the amount of background shading becomes

 

unacceptable:

 

Change to a lighter weight paper. (Page 4.3)

 

Check the environmental conditions: very

 

 

dry conditions (low humidity) or a high level

 

 

of humidity (higher than 80% RH) can

 

 

increase the amount of background

 

 

shading.

 

Remove the old drum cartridge and then,

 

 

install a new one. (Page 10.3)

Toner smear

Clean the inside of the machine. Contact a

 

 

 

service representative.

 

 

 

 

 

Check the paper type and quality.
