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.

Turn off the printer, open the paper roll cover, and clean the thermal element of the print head with a cotton swab moistened with an alcohol solvent (ethanol, methanol, or IPA). See the illustration below.

EPSON recommends cleaning of the thermal head periodically (generally every three months) to maintain receipt print quality.

Using Different Paper Widths

The TM-L90 accommodates 80 mm wide paper rolls with no adjustments. For rolls from 38 mm to 70 mm wide you use the spacer included with the printer. (If the rolls are from 61 to 70 mm wide, you break two tabs off the spacer. See the width note below.)
