Skew check
What to do?
Determine a paper path issue.

    Tray 1
    with 20lb. Letter or A4 size paper. Make sure the paper-tray guides are properly seated for the paper size loaded.
  2. Print
    Quality Pages
     again to determine success. If you no skew if present from tray 1, repeat these steps to isolate additional trays until you can identify the source.
Operating conditions check
What to do?
Request information about the printer environrment's temperature, humidity and air quality conditions.
If any indicators suggest poor operating conditions, then ask the customer to relocate printer to a different location, and then print the
Quality Pages
 again to determine success.
Other checks
  • Check that the
    proper print driver
    (PCL, PS, XPS) is installed for a particular file type or application.
  • Change drivers
    to determine any change in print quality.
  • Adjust
    driver settings
    when applicable.
  • Check
    Scan Settings
     under
    Copy Setup
    .
  • Check
    scanner platen glass
    and
    ADF glass
     for debris.
  • Compare
    simplex
     vs.
    duplex print output
     to identify issue occurs on both sides of the page.
  • Look for
    consistent
     and
    repeatable
     anomalies versus
    inconsistent
    and
    random
     anomalies to better understand the nature of the print problem.
