English
Do not block the label peeler detector with your fingers, or anything else while the label
issuing is in progress. This may cause the printer to feed the following label.

When installing roll paper, be careful not to injure your hands on the manual
cutter.
Troubleshooting
ERROR LED is on or flashing
❏
Make sure that the roll paper cover is closed and the PAPER OUT LED is not
on. Close the cover or replace the paper if necessary.
❏
If the printer has been printing a lot and the print head gets too hot, the
ERROR LED starts flashing, and printing stops. When its temperature cools
down to the normal range, printing resumes automatically.
❏
Turn off the printer and then turn it back on. If the LED is still flashing,
consult with your supervisor or a service person.
PAPER OUT LED is flashing
If the PAPER OUT LED continues to flash even after the issued label is removed,
the label peeler detector may be detecting something. Press the PAPER FEED
button once.
Paper jam
Turn off the power, open the peeler cover, and then open the roll paper cover to
check for a paper jam. If there is a paper jam, remove the jammed paper and
follow the instructions in the Installing Roll Paper section to prepare the printer
for printing.
