Solution

What you will see


All scanned images and printouts appear light or faded when printed.
 

Determine first if the scanner unit is at fault


To find out if the issue involves the scanner unit or the base printer, try printing documents that do not use the scanner unit, such as a file from the computer or network. Alternatively, you can choose to print the internal settings pages by using the menus on the printer's operator panel. NOTE: To print the settings pages, press the Menus button to enter the menus. Select Reports and then select Menu Settings Page. The printer will display the message Printing Menu Settings Page, then print the pages.
  • If the quality of print on these pages continues to be light, the cause of the issue is probably a low toner cartridge or a setting or a part on the base printer. Click here for further suggestions and settings to check on the printer. 
     
  • If the quality of print on these pages appears correct and it is only on scanned images or documents that the print is light, continue with the suggestions below.
      

Change the imaging settings on the scanner

    • Record the original values for each of these settings before changing them. If you are unable to correct the issue after changing the settings listed in the table below, restore the settings back to their original values before arranging a service call.
       
    • The directions in the table below for navigating the menus apply to the X644 and X646 models only. If you have an X642 model printer, please see the User's Guide for directions on how to navigate the menus and change the settings.
