If you make borderless prints with your all-in-one printer, some prints may have ink contamination on the back side. 

Do the following to resolve this problem:

  • Make sure that all sheets in the paper tray are the same width.
  • Move the paper guides in until they just touch the paper so that each sheet travels in the same path through the printer.
  • Wait a couple of minutes between prints.
  • Make prints with borders.
