    DropoutsIf 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 Selecting print media on page 24.
    • 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 printer properties, click  Paper tab, and 
    set type to  Thick Paper . Refer to the 
    Software section  for details.
    If these steps do not correct the problem, 
    contact a service representative.
    White Spots  White spots appear on the page:
    • The paper is too rough and a lot of dirt from 
    the paper falls to the inner devices within 
    the printer, which means the transfer belt 
    may be dirty. Clean the inside of your 
    printer. Contact a service representative.
    • The paper path may need cleaning.  Contact a service representative.
    Vertical linesIf 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 Replacing the toner cartridge on 
    page 53.
    If white vertical streaks appear on the page:
    • The surface of the LSU part inside the  printer may be dirty. Clean the LSU, 
    contact a service representative.
    Color or Black 
    backgroundIf the amount of background shading becomes 
    unacceptable:
    • Change to a lighter weight paper. See Selecting print media on page 24.
    • Check the printer’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. See Replacing the toner 
    cartridge on page 53.
    Toner smear• Clean the inside of the printer. 
    See Cleaning the inside on page 50.
    • Check the paper type and quality. 
    See Selecting print media on page 24.

    Vertical repetitive 
    defectsIf 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, print a 
    cleaning sheet several times to clean the 
    cartridge. After the printout, if you still have 
    the same problems, remove the toner 
    cartridge and install a new one. 
    See Replacing the toner cartridge on 
    page 53.
    • 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.
    Background scatterBackground 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 pr inted 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 Selecting print media on page 24.
    • If characters are improperly formed and  producing a wavy effect, the scanner unit 
    may need service. For service, contact a 
    service representative.
    Page skew• Ensure that the paper is loaded properly.
    • Check the paper type and quality. See Selecting print media on page 24.
    • Ensure that the paper or other material is  loaded correctly and the guides are not too 
    tight or too loose against the paper stack.
