10.4 Print Head Maintenance

If print quality has not improved after using a thermal cleaning card, or if one is not

available, foam or cotton tipped swabs or a clean lint-free cloth dampened with isopropyl

alcohol may be used. Follow the steps below to clean the print head.

1. Release the Print Head Assembly and rotate to the open position.

2. With a foam or cotton tipped swab or soft, lint-free cloth dampened with isopropyl

alcohol, clean the thermal elements by gently rubbing the swab down the length of

the print head dot row. Allow for the alcohol to evaporate, then repeat if necessary.

3. Reinstall media and run labels to check print quality.

4. If poor print quality persists, print head or other parts may be damaged.
