Reseating or Replacing the Print Head

On very rare occasions, like a print head error condition or poor print quality issues, it may be necessary to reseat or remove the print head and replace it with another.

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

Removing the Print Head:

 

  1. Make sure that the power is turned on, then, holding sides of the paper output tray, gently open it.
     
  2. Lift the operation panel open until it stops.
    The print head holder will move to ink tank replacement position.


     
  3. Push the tab (A) on an ink tank and lift it out of the printer.


     
  4. Remove the rest of the ink tanks from the holder.


     
  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. 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.


     
  7. 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.


     
  8. Now go to section Installing (or Reseating) the Print Head.

 


Installing (or Reseating) 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.


     
  4. Once the print head is seated in the print head holder, push the Head Set Lever towards the back of the machine.


     
  5. Reinsert the ink tanks into their proper slots.


     
    1. Insert the front end of the ink tank into the print head at a slant. Make sure that the position of the ink tank matches the label.


       
    2. Press on the top of the ink tank until the ink tank snaps firmly into place.  Make sure that the ink lamp lights up red.



       
  6. Close the operation panel.

If the print head carriage returns to home position before the print head is installed, close the operation panel and follow the instructions on the display. Then repeat step 3 to get the print head holder into the replacement position.
