Thermal printhead cleaning
The thermal printhead for the customer receipt and journal stations 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 as shown in
Figure 2-10.
3. Wipe off any residual alcohol with a dry swab.
If print quality does not improve after cleaning the thermal printhead, call for
service. These instructions apply to either the customer receipt or journal printhead.
