Troubleshooting

Check whether the DC cable and AC cable are correctly connected to the printer
and the power outlet. (See "Connecting to a Power Source" on page 6.)
ERROR LED on (not flashing) with no printing
❏ Check whether the roll paper cover is closed. If it is open, close it.
❏ If PAPER OUT LED is on, check whether the roll paper is correctly installed and
any roll paper remains.
ERROR LED flashing with no printing (and no paper jam)
Printing stops if the thermal head overheats and resumes automatically when it
cools.
For other cases, turn the printer off, and after 10 seconds, turn it back on.
No connection to external devices
When the status LED (S 32) is lit in green
❏ Check whether the interface cable or the wireless LAN cable set (optional product) is
connected correctly. (See "Connecting to External Devices" on page 6.)
❏ Print the status sheet to check whether the network settings are correct. (See
"Confirming the Network Settings" on page 8.)
When the status LED (S 32) is off / lit in orange
When the status LED is off after turning on the printer or remains lit in orange
even if 30 seconds have passed after turning on the printer, the interface board
needs repairing.
Paper is jammed
CAUTION:
Do not touch the thermal head because it can be very hot after printing.
1. Turn the printer off, lift the cover open lever and open the roll paper cover.
2. Remove jammed paper, reinstall the roll, and close the roll paper cover.
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 (T 33) indicated by a circle
in illustration T and push the cover upward. After removing the cutter cover, turn
the knob with a ballpoint pen or tweezers in the direction indicated by the arrow
until you see a triangle mark in the opening.
