If the inside of the printer is dirty, or paper is improperly loaded, print quality maybe 

reduced. See the table below to clear the problem. 

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 “Redistributing Toner” on 

page 7.7. 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 

• If the entire page is light, the print resolution setting is too 

low or Toner Save mode is on. Adjust the print resolution and 

turn Toner Save mode off. See page 3.8 and page 1.27 

respectively.

• A combination of faded or smeared defects may indicate that 

the toner cartridge needs cleaning. See “Cleaning the Drum” 

• The surface of the document glass may be dirty. Clean the 

document glass. See page 7.5.

• The surface of the LSU may be dirty. Clean the LSU. See 

• The paper may not meet specifications; for example, the 

paper is too moist or too rough. See “Paper Specifications” on 

• The transfer roller or paper path may be dirty. Clean the 

inside of your machine and the drum. See page 7.3 and 

If generally rounded faded areas, 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” on page A.5.

• 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.
