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 should be cleaned at regular intervals or when the print
quality has noticeably deteriorated. There are many factors that affect cleaning
frequency. Poor paper quality, high printer usage, or a dirty environment are all
reasons to clean the thermal printhead more often. Complete the following steps to
clean the thermal printhead:
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.
