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
Turn off the power and open the roll paper cover to remove the jammed paper. After that,
install the roll paper correctly. If the roll paper cover will not open, see the section below.
If glue or another foreign substance is present on the autocutter blade, platen roller, or the
paper path, a paper jam is likely to occur. See "Cleaning the Thermal Head" on page 17 for
cleaning instructions.
