Thermal Printhead Cleaning

The thermal printhead can be cleaned whenever print quality deteriorates.

1. Open the paper cover.

2. Using a cotton swab soaked in isopropyl alcohol, gently wipe the printhead

several times on its print line and on the surrounding area. See Figure 30.

3. Wipe off any residual alcohol with a dry swab.

If print quality does not improve after cleaning the thermal printhead, call for
service.
