Condition Vertical lines Suggested solutions If black vertical streaks appear on the page: • The drum inside the toner cartridge has probably been scratched. Install a new toner cartridge. See page 8.4. If white vertical streaks appear on the page: • The surface of the LSU part inside the printer may be dirty. Clean the LSU. See page 8.2. Gray background Toner smear If the amount of background shading becomes unacceptable, the procedures below may fix the problem. • Change to lighter weight pages. See page 5.3. • Check the printer's environment; low humidity (lower than 20% RH) 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 page 8.4. • Clean the inside of the printer. See page 8.1. • Check the paper type and quality. See page 5.2. • Remove the toner cartridge and install a new one. See page 8.4. Vertical repetitive defects If 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, install a new toner cartridge. See page 8.4. • 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. Condition Background scatter Misformed characters Suggested solutions Background 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 via the printer properties window. • If characters are improperly formed and producing hollowed images, the paper stock may be too slick. Try a different paper. See page 5.3. Page skew • Ensure that the paper is loaded properly. • Check the paper type and quality. See page 5.2. • Ensure that the paper is loaded correctly and the adjustable guides are not too tight or too loose against the paper stack. Curl or wave • Ensure that the paper is loaded properly. • Check the paper type and quality. Both high temperature and humidity can cause paper curl. See page 5.2. • Turn over the stack of paper in the tray. Also try rotating the paper 180° in the tray. 9.8
