Replacing the Printhead
If you need to replace the printhead, read the procedure and review the removal and
installation steps before actually replacing the printhead.
Printhead Removal
1. Open the printer. Remove any transfer ribbon from the printer.
2. Use a small flat bladed screwdriver to remove the ribbon guide. Gently pry the guide
right-side tab from the ribbon frame. Pull the left side of the ribbon guide out.
Caution • Prepare your work area by protecting against static discharge. Your work area
must be static-safe and include a properly grounded conductive cushioned mat to hold the
printer and a conductive wrist strap for yourself.
Caution • Turn the printer power off and unplug the power cord before replacing the
printhead.
