Cleaning
Cleaning the Printer Case
Before cleaning the printer case, be sure to power off the printer, and wipe the
dirt off the printer case with a soft wiping cloth we provide.
Do NOT clean the product with alcohol, benzene, thinner, or
other such solvents. Doing so may damage or break the parts
made of plastic and rubber.
Cleaning
the Thermal Head and the Platen Roller
In most cases, it is strongly recommended to regularly cleaning the thermal
head to maintain receipt print quality (about once every 3 months). While
using the printer, always ensure that dust particles are removed from paper
rolls and the gear by using the platen roller with a cotton swab moistened with
water. Then, power on the printer only after water has dried.
After printing, the thermal head and its surroundings
can be overheated. Make sure that it is completely
cooled down before cleaning it.
Do not damage the thermal head with your fingers or
any other hard object.
