Cleaning The Print Head - Epson TM-L90 Bedienungsanleitung

The roll paper cover will not open
Turn on the printer and remove the cutter
cover. To remove the cover, use a tool
such as a screwdriver, and insert it into
one of the slots indicated by a circle in the
illustration and push the cover upward.
After removing the cutter cover, use a
ballpoint pen or tweezers to turn the knob
in the direction indicated by the arrow
until you see a triangle in the opening.

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.)
