TM-L90 User’s Manual 17

Troubleshooting

Printout is faint

When printout is faint, adhesive glue or another foreign substance may be present on the thermal head, platen roller, or paper path of the printer.

In such case, first clean the thermal head by following the instructions described in

“Cleaning the Thermal Head” on page 17.

If the print quality does not improve, clean the platen roller and paper path of the printer

by following the instructions described in “Cleaning the Thermal Head” on page 17.

ERROR

LED on or flashing

❏ Check to see that the roll paper cover is closed and check the PAPER OUT

LED. Close the cover or replace the roll paper if necessary.

❏ If the printer has been printing a lot, the thermal head may be hot. Wait for the head to cool. Printing will resume automatically.

❏ Open the roll paper cover, and check to see if the paper is jammed. If a paper jam occurs or if the roll paper cover will not open, see the section below.

❏ Turn the printer off and back on. If the LED is still flashing, notify your manager. The printer may require servicing.

Paper jam
