Cleaning the Print Head Path

If the print quality has not improved after aligning the print head and cleaning the paper guide, the print head path inside the product may be smeared with ink.
To clean the print head path, use the following:
  • Several cotton swabs
  • ΒΌ cup (59 ml) water containing 2 to 3 drops of mild dish detergent
  • A small flashlight
Do not use any other liquid to clean the print head path or you may damage your product.
  1. Turn off the product.
  2. Unplug the power cable.
  3. Disconnect any connected cables.
  4. Lift up the scanner unit.

  5. Using the flashlight, check the translucent film shown here for ink smears.

    1 Translucent film
    2 Print head rail (do not touch)
    Do not touch the flat white cable or the print head rail; otherwise, you may not be able to print. Do not wipe off the grease on the rail.
  6. Moisten a cotton swab with the water and detergent mixture and squeeze out any excess moisture. Use it to lightly wipe ink off the translucent film.

    Do not press too hard on the film or you may dislocate the anchor springs and damage the product.
  7. Use a new, dry cotton swab to dry the translucent film.
  8. Repeat steps 6 and 7 as necessary to clean all ink smears.
