Cleaning Thermal Head / Platen / Rubber Feet
Turn off the printer.
Unplug the AC plug of the AC cable from the outlet.

NOTE
◆
Clean the thermal head after it cools down.
◆
Be sure to wipe the thermal head with a cotton swab or other soft material.
◆
DO NOT touch the cutter blade directly.
◆
Make sure not to injure your body or other objects as the sheet metals around the
thermal head and the cutter have sharp edges.
◆
DO NOT touch the gear of the platen. Doing so may cause loss of printing quality or a
failure.
◆
The rubber feet have the special adsorption structure. They lose adsorption force as
dust or dirt adheres. However, it can be recovered by cleaning.
