This procedure guides you through replacing the printhead.
Read this procedure first before you begin your repair.
Turn the printer OFF.
Open the printer to gain access to the printhead (1).
The printhead becomes hot while printing. To protect from damaging the printhead and risk of personal injury, avoid touching the printhead. Only use the cleaning pen to perform printhead maintenance.
The discharge of electrostatic energy that accumulates on the surface of the human body or other surfaces can damage or destroy the printhead and other electronic components used in this device. You must observe static-safe procedures when working with the printhead or the electronic components under the top cover.
Push the printhead release latch away from the printhead. The right side of printhead releases.
Swing the loose right side of the printhead out of the printer. Pull it out and to the right a little to get the left side of the printhead clear. Pull the printhead out and free of the top cover to gain access to its attached cables on the backside of the printhead. Note, the redline highlights the left side printhead retainer slot.
Gently but firmly pull the two printhead cable bundle connectors (1) off of the printhead (2). Pull the ground wire (3) off the printhead.
Align the printhead up to the printer. Push the right-side printhead cable connector into the printhead. The connector is keyed to only insert one way.
Attach the ground wire to the printhead’s ground tab.

Align the spring wire notch (1) on the backside of the printhead to the spring wire. Push the right side of the printhead into the printer until the latch locks the right side of the printhead into the printer.
Verify that the printhead moves up and down freely when pressure is applied and remains locked when released.
