5 Cleaning
Wipe off any foreign matter such as ribbon or paper residue, dust and adhesive substance
stuck to the thermal head, ribbon guide roller, platen etc with the accessory cleaning pen or
a soft cloth soaked in ethyl alcohol. Cleaning of the thermal head is essential to guarantee
print quality and extend print head life especially when printing on the direct-thermal paper
for long periods.
Caution: Do not use solvent other than ethyl alcohol such as benzene and thinner that will
dissolve plastic.
