Install 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 green circuit board on the back of the print head, 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. Slide the replacement print head into the machine.
  4. Once the print head is seated in the print head holder, push the Head Set Lever towards the back of the machine.
  5. Close the inner cover.
  6. Insert the ink tanks into their proper slots.
  7. Close the ink cover and then the document cover.
  8. If the print head carriage returns to home position before the print head is installed, close the inner cover and operation panel and follow the instructions on the display. Then open the inner panel.
