Cleaning the Thermal Print Head
CAUTION:
After printing, the thermal print head can be very hot. Be careful not to
touch it. Also let it cool before you clean it. Do not damage the thermal
print head by touching it with your fingers or any hard object.
To keep good print quality, remove paper dust from the thermal
print head as follows.
Be sure that the printer is turned off. Open the roll paper cover and
clean the thermal element (the green part) of the thermal print head
with a cotton swab moistened with an alcohol solvent (ethanol,
methanol, or IPA).
Clean the thermal print head periodically (generally every 3
months) to maintain receipt print quality.
