Condition White Spots Vertical lines Color or Black background Toner smear Suggested solutions White 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. See page 10.2. Contact a service representative. • The paper path may need cleaning. Contact a service representative. If black vertical streaks appear on the page: • The drum inside the toner cartridge has probably been scratched. Remove the toner cartridge and install a new one. See page 10.5. If white vertical streaks appear on the page: • The surface of the LSU part inside the machine may be dirty. Clean the LSU. See page 10.2. If the amount of background shading becomes unacceptable: • Change to a lighter weight paper. See page 5.1. • Check the machine'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.

If a repetitive mark occurs on the page, print a cleaning sheet several times to clean the cartridge; see page 10.4. After the printout, if you still have the same problems, remove the toner cartridge and install a new one. See page 10.5. • Parts of the machine 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 scatter A Background scatter results from bits of toner randomly 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 producing hollow images, the paper stock may be too slick. Try a different paper. See page 5.1. • If characters are improperly formed and producing a wavy effect, the scanner unit may need service. For service, contact a service representative. Page skew AAAAaAaaaBaBBBbBbbbCbCCCCccccc • Ensure that the paper is loaded properly. • Check the paper type and quality.
