Cleaning the Print Head

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