My printout has lines running through it. What should I do?

• If you notice white or dark lines in your prints (also called banding), try these solutions before you reprint:
  • Clean the print head.
  • Make sure the paper type setting matches the type of paper you loaded.
  • Make sure you loaded the printable side of the paper facedown in the cassette or faceup in the rear MP tray.
  • Turn off any high speed settings in your product software.
  • Align the print head.
  • You may need to replace the ink cartridges.
