Solving other problems 29 Printing quality problems If the inside of the machine is dirty or paper has been loaded improperly, there might be a reduction in print quality. See the table below to clear the problem. Condition Light or faded print Suggested Solutions • 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 color tone might not be adjusted. Adjust the color tone. • The paper may not meet paper specifications; for example, the paper may be too moist or rough (see "Print media specifications" on page 285). • 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. • 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. Condition Toner specks Dropouts Suggested Solutions • The paper may not meet specifications; for example, the paper may be too moist or rough (see "Print media specifications" on page 285). • 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. • Check the location of the machine. If the area is not wellventilated, this problem may occur. 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 (see "Print media specifications" on page 285). • The paper lot is bad. The manufacturing 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 Printing Preferences, click Paper tab, and set type to thick paper (see "Opening printing preferences" on page 70). • If these steps do not correct the problem, contact a service representative. 9.
