Chapter 6 Maintenance
6.3 Cleaning the Thermal Head
When the thermal head becomes dirty or has refuse attached, it is not possible to make a clean print, and white lines
will appear in the printing.
Clean the thermal head regularly, and take care so that the print quality does not deteriorate. There are 3 thermal heads,
and are arranged as Head 3, Head 2 and Head 1 from the top as shown in the illustration.

Clean without mechanical impact to the thermal head heating element.
• Upon performing maintenance, in order to prevent the likes of electrostatic disruption and corrosion,
please do not directly touch the thermal heads with your hands. Ensure not to do the same for the media
surface that the thermal heads come into contact with.
• Upon cleaning the thermal heads, please use the attached cleaning stick. (Please absolutely refrain from the
use of cotton swabs, etc., which may cause fibers to stick to the thermal heads and result in product failure.)
• Before use, be sure to read the Thermal Head Cleaner (THC-1) handling instructions.
Cleaning
Referring to "6.2 Removing/Mounting the Ribbon Stocker", remove the ribbon stocker section and clean the thermal head.
As for the cleaning method, open the thermal head section, and gently wipe the heating element section at the tip of the
head with the attached cleaning stick as shown.

Since there is the possibility of damaging the head if you rub it forcefully or wipe it with a cloth that has not been
specified, wipe it only with a cleaning stick.
When heavily soiled, put a small amount of Thermal Head Cleaner THC-1 on the tip of the cleaning stick and clean
the thermal head. Then, wipe off the cleaning fluid with a dry cleaning stick. If the cleaning fluid remains on it, printing
quality may be adversely affected.
Never use the THC-1 to clean other products.
So as to not damage it, never strike or scratch it with a sharp or hard object.
Upon performing maintenance, in order to prevent the likes of electrostatic disruption and corrosion, please do not
directly touch the thermal heads with your hands. Ensure not to do the same for the media surface that the thermal
heads come into contact with.
