7. Periodic Cleaning
At times, the printer might leave some characters partially unprinted due to paper particles or
debris from the adhesive used on label paper. As a preventive measure, clean the printer regularly
every month or after printing 200,000 lines.

7-1. Cleaning the Thermal Head and Ground Hardware

Use the optional head cleaner as shown to remove the grime from the thermal head. A cotton swab
or soft cloth dipped in an alcohol solution (such as ethanol, methanol, or isopropyl alcohol) may
be used instead of the head cleaner. Follow the cleaning instructions below.
(1) Cut off the power to the printer by turning
OFF the power switch.
(2) Push the front cover to open the printer
cover.
(3) Using the head cleaner, wipe off the black
paper particles that have accumulated on
the thermal head surface.
(4) Likewise, use the head cleaner to wipe off the
paper particles that have accumulated on the
ground hardware above the thermal head.
Notes
1: Do not clean the thermal head immediately after printing, because the thermal head is hot.
2: While cleaning the thermal head, be careful not to create static electricity, which poses
the risk of problems such as damage to the head.
3: Turn the power ON only after the alcohol solution has completely dried.

7-2. Cleaning the Printer Cover, Paper Guide, and Peeler Sensor

Using a cotton swab or soft cloth dipped in an alcohol solution (such as ethanol, methanol, or
