Cleaning the Printhead
Always use a new cleaning pen on the printhead (an old pen carries contaminants from its
previous use that may damage the printhead).
When you load new media, you can also clean the printhead.
1. Pull the two (2) Release Arms out to release the Ribbon Drive Transport. The arms are
located on the left and right sides of the printer. The Ribbon Drive Transport and Printhead
Actuator Arm will now be loose.
2. Swing the Printhead Actuator Arm up until it touches the printer’s top cover. Hold the
Printhead Actuator Arm in this position for access to the printhead.
Caution • The printhead becomes hot while printing. To protect from damaging the
printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning
pen to perform maintenance.
