Cleaning the Print Head
Caution After printing, the print head can be very hot. Be careful not to touch it, and to let it cool before you
clean it. Do not damage the print head by touching it with your fingers or any hard object.
Take the following steps to clean the print head:
1 Turn off the printer, open the paper roll cover, and clean the thermal elements of the
print head with a cotton swab moistened with an alcohol solvent (ethanol, methanol, or
IPA).
2 Checkpoint Systems recommends that you clean the thermal head periodically
(generally every 3 months) to maintain receipt print quality.
