    							General print quality issues
    The following examples depict Letter-size paper that has passed through the product short-edge first.
    These examples illustrate problems that would affect all of the pages that you print, whether you print
    in color or in black only. The topics that follow list the typical cause and solution for each of these
    examples.
    ProblemCauseSolution
    Print is light or faded.The media might not meet
    HP specifications.Use media that meets HP specifications.
    One or more print cartridges might be
    defective.Print the Supplies status page to check
    the remaining life. See 
    Information pageson page 68.
    Replace any low print cartridges. See
    Replace print cartridges on page 82.
    The product is set to override the
    Replace  cartridge message
    and to continue printing.Replace any low print cartridges. SeeReplace print cartridges on page 82.
    The print density settings may have been
    changed.Set the print density setting to 0.
    The product may need to be calibrated.Run a calibration. See Calibrate theproduct on page 118.
    Toner specks appear.The media might not meet
    HP specifications.Use media that meets HP specifications.
    The paper path might need cleaning.Clean the paper path. See Clean theproduct on page 90.
    One or more of the cartridges may be
    leaking.Try to verify the color of the toner specks
    and check the cartridge for leaks.
    The cartridge waste tank may be
    overfilled.Check for error code 10.98.XX in the
    event log. See Event log on page 70. The
    XX portion of the code identifies the
    cartridge (00 is black, 01 is cyan, 02 is
    magenta, 03 is yellow). If the error was
    logged, replace the affected cartridge.
    Dropouts appear.A single sheet of print media might be
    defective.Try reprinting the job.
    The moisture content of the paper is
    uneven or the paper has moist spots on
    its surface.Try different paper, such as high-quality
    paper that is intended for color laser
    printers.
    The paper lot is flawed. The
    manufacturing processes can cause
    some areas to reject toner.Try different paper, such as high-quality
    paper that is intended for color laser
    printers.

    In your software program, rotate the
    whole page 180° to print the lighter
    image first.
    The order of images printed might affect

    							Use HP ToolboxFX to troubleshoot print-quality problems 
    NOTE:Before proceeding, print a Supplies status page to see the approximate number of pages
    remaining for each print cartridge. See 
    Information pages on page 68.
    From the HP ToolboxFX software you can print a page that helps identify whether a specific print
    cartridge is causing the problem, or if the problem is with the product itself. The print-quality
    troubleshooting page prints five bands of color, which are divided into four overlapping sections. By
    examining each section, you can isolate the problem to a particular cartridge.
    SectionPrint-cartridge
    1Yellow
    2Cyan
    3Black
    4Magenta
    This page helps identify four general issues:
    ●Streaks in only one color: This is most likely a cartridge issue. Remove the cartridge and look
    for debris on it. If no debris is found and the defect continues after the cartridge is reinstalled,
    replace the cartridge.
    ●Streaks in all colors (in same location): Clean the printer and call for service if the problem
    continues.
    ●Repeating defect in multiple colors:
    Repeating dot in multiple colors: If the dot repeats at roughly 57 or 58 mm, run a cleaning page to
    clean fuser and run several white pages of paper to clean the roller. If defect does not repeat at 57
    or 58 mm, replace the cartridge of the color of the dot.
    Repeating band in multiple colors: Contact HP Support.
    ●Single dot or Single band in one color: Print three or four additional troubleshooting pages. If
    the band or dot is only in one color on most of the pages, replace the cartridge of that color. If the
    band or dot moves to a different color, contact HP Support.
