  • Load the original document into the feeder correctly, using the paper guides, to avoid unclear or skewed images, when using the document feeder.
  • If there is an issue with the scan image quality, then try to clear the smudges and dirt accumulated on the scanner glass.
  • To clear the dirt, turn off the printer and then open the scanner lid. Using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner, clean the scanner glass, the document feeder strips, and the white plastic backing.
  • To prevent spotting, dry the glass and white plastic parts with a chamois or a cellulose sponge.
  • Then turn on your printer and check if the issue is resolved.
  • If the printed pages have toner smudges or skewed print, clean the pickup rollers and separation pad in the document feeder.

  • If you find an Out of memory status message on the printer’s control panel then it indicates that the printer storage disk is full. So you should delete some stored jobs from the disk.

  • Try setting the Optimize Text/Picture option to Photograph setting and check if the issue is resolved.

  • Set the overlay header to overlay mode, or alter the fit-to-page setting to print a one page fax on one page if a one-page fax print as two pages.
