Caring for Your Printer

After using eight rolls of label stock, clean the following areas of
the printer.
Note: Always switch off the power before cleaning.
Cleaning
Clean the following components of the printer using a cotton bud
dampened with alcohol. Do not soak the cotton bud excessively.

Thermal Print Head

Thermal paper stock and the ribbon release debris on the print
head, which degrades printing quality. Clean the print head with
methanol or isopropyl alcohol and a cotton bud. Do not touch the
heater element with your fingers. Debris or dirt on the roller
should be cleaned with alcohol.

Paper Sensor

Debris or dirt on the paper sensor can cause a miss-read or
unstable detection of the label gap. Clean with a cotton bud
dampened with alcohol.
