On rare occasions, like a print head error or poor print quality issues, it may be necessary to reseat or remove the print head from the printer.

Reseat or replace the print head

Follow these steps to remove the print head. Later in this document you'll be given instructions to reinstall or install the print head.

Remove the print head:

  1. With the printer powered on, then, holding the sides of the paper output tray, gently open it.

  2. Lift the entire operation panel open until it stops.
    The print head holder will move towards the center to ink tank replacement position.

  5. After all the ink tanks have been removed from the holder, press and hold the Stop button for two seconds (or longer) until the print head carriage moves to the replacement position and then release the button.

    The carriage will move to the right and then return almost centered with the front opening.
  6. Open the the inner cover (B) and push it down all the way to the bottom.

  7. Pull the Head Set Lever towards the front of the machine. You may find resistance when the bottom of the Head Set Lever hits the back of the front edge. The Head Set Lever will move forward as it slides above that front edge.

  8. Use your finger tips to grab the top of the center tab and pull out the print head. You will notice the front of the print head will drop face down as you pull it out of the machine.

  9. Now go to the section Install (or Reseat) the Print Head.

Install (or Reseat) the Print Head:

  1. If you are installing a replacement print head, remove it from its packaging.

  2. Hold the center tab of the replacement print head, with the front of the print head facing down so you can see the back of the print head (green circuit board). And, ensure the two tabs on the front, bottom corners of the print head are inserted into the rails on either side of the print head holder.

  3. Now slide the replacement print head into the machine.

    As the print head slides into the holder, it will start to sit in an upright position.
