Remove the print head:

  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.

  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.
