Thermal print head cleaning
The thermal print head can be cleaned whenever print quality deteriorates.
1. Open the paper cover.
2. Using a cotton swab soaked in isopropyl alcohol, gently wipe the print head
several times on its print line and on the surrounding area. See Figure 42.
3. Wipe off any residual alcohol with a dry swab.
If print quality does not improve after cleaning the thermal print head, call for
service.
