Cleaning The Print Head - Seiko Epson M147B Manuel D'utilisation

Cleaning the Print Head

After printing, the print head can be very hot. Be careful not to touch it.
Also let it cool before you clean it. Do not damage the print head by
touching it with your fingers or any hard object.
Open the paper roll cover, and clean the thermal element (the green
part) of the print head with a cotton swab moistened with an
alcohol solvent (ethanol, methanol, or IPA).
Clean the thermal head periodically (generally every 3 months) to
maintain receipt print quality.
