Cleaning recommendations
You should inspect your 4610 unit periodically and clean the cover as required. Use a soft, clean cloth with
warm, soapy water to clean the plastic parts. Do not use abrasives or any alkaline, ammonia, or
chloride-based cleaner.
Note: Do not apply cleaning solution directly to the cover. Always apply the cleaner to a clean cloth and
then wipe the cover with the damp cloth. Be certain that the cloth is only damp and not dripping
wet.
Cleaning the thermal printhead
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.
3. Wipe off any residual alcohol with a dry swab.
If print quality does not improve after cleaning the thermal printhead, run the Thermal Printhead Health
Test. If print quality still does not improve, call for service.
