Printing Quality Problems
The inside of the printer may be dirty or improper paper loading may reduce the print quality. See the table 
below to clear the problem.
Condition Suggested solutions
Light or faded printIf 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 
Redistributing Toner. 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 
Paper Specifications.
• A combination of faded or smeared defects may indicate that the toner cartridge needs 
cleaning. See 
Cleaning the Interior.
• The surface of the LSU part inside the printer may be dirty. Clean the LSU (see 

Cleaning the Interior).
To n e r  s p e c k s• The paper may not meet specifications; for example, the paper is too moist or too rough. 
See 
Paper Specifications.
• The transfer roller may be dirty. Clean the inside of your printer. See 
Cleaning the 
Interior.
• The paper path may need cleaning. See 
Cleaning the Drum.
DropoutsIf 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. See 
Paper Specifications.
• The paper lot is bad. The manufacturing process can cause some areas to reject toner. Try 
a different kind or brand of paper.
• The toner cartridge may be defective. 
Vertical repetitive defects on the next page.
•  If these steps do not correct the problems, contact a service representative.

White SpotsWhite 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. Contact a 
service representative.
• The paper path may need cleaning. Contact a service representative.
Ve r t i c a l  l i n e s• If black vertical streaks appear on the page, the drum inside the toner cartridge has 
probably been scratched. Install a new toner cartridge. See 
Replacing the Toner 
Cartridge.
• If white vertical streaks appear on the page, the surface of the LSU part inside the printer 
may be dirty. Clean the LSU (see 
Cleaning the Interior).
Gray backgroundIf the amount of background shading becomes unacceptable:
• Change to lighter weight pages. See Paper Specifications.
• Check the printer’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 
Replacing the Toner 
Cartridge.
To n e r  s m e a r•Clean the inside of the printer. See Cleaning the Interior.

Vertical repetitive defectsIf marks repeatedly appear on the printed side of the page at even intervals:
• The toner cartridge may be damaged. If a repetitive mark occurs on the page, print a 
cleaning sheet several times to clean the cartridge; see 
Cleaning the Drum. After the 
printout, if you still have the same problems, install a new toner cartridge. See 
Replacing 
the Toner Cartridge.
• Parts of the printer may have toner on them. If the defects occur on the back of the page, 
the problem will likely correct itself after a few more pages.
• The fusing assembly may be damaged. Contact a service representative.
Background scatterBackground scatter results from bits of toner distributed on the printed page. 
• The paper may be too damp. Try printing with a different batch of paper. Do not open 
packages of paper until necessary so that the paper does not absorb too much moisture.
• If background scatter occurs on an envelope, change the printing layout to avoid printing 
over areas that have overlapping seams on the reverse side. Printing on seams can cause 
problems.
• If background scatter covers the entire surface area of a printed page, adjust the print 
resolution through your software application or the printer properties.
Misformed characters• If characters are improperly formed and produce hollow images, the paper stock may be 
too slick. Try a different paper. See 
Paper Specifications.
• If characters are improperly formed and produce a wavy effect, the scanner unit may need 
service. For service, contact a service representative.
Pa g e  s k e w• Ensure that the paper is loaded properly.
• Check the paper type and quality. See 
Paper Specifications.
• Ensure that the paper or other material is loaded correctly and the guides are not too tight 
or too loose against the paper stack.

Replacing the Toner Cartridge.
• If the problem persists, the printer may require repair. Contact a service representative.
Character VoidsCharacter voids have white areas where they should be solid black:

composition of the transparency, some character voids are normal. 
• You may be printing on the wrong surface of the paper. Turn over the stack of paper in the 
paper tray.
• The paper may not meet paper specifications. See 
Paper Specifications.
Horizontal stripesIf horizontally aligned black streaks or smears appear:
• The toner cartridge may be installed improperly. Remove the toner cartridge and reinsert.
