You may be able to temporarily extend the toner cartridge life. See "Redistributing the Toner" on page 6.5. If this does not improve the print quality, install a new toner cartridge of faded color. • The paper may not meet paper specifications (for example, the paper is too moist or too rough). See "Paper Specifications" on page D.4. • A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. See page 6.31. • The surface of the LSU may be dirty. Clean the LSU. See page 6.30. • The paper may not meet specifications (for example, the paper is too moist or too rough). See "Paper Specifications" on page D.4. • The transfer roller or the paper path may be dirty. See "Cleaning the Inside of the Printer" on page 6.31. 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 D.4. • 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. See "Vertical repetitive defects" on the next page. • If these steps do not correct the problems, contact a service representative. 7.22 SOLVING PROBLEMS
