Cannot Print
If you cannot print from the printer even though no errors have occurred, run a self-test to see if you can print
with the printer alone. If the printer is connected to a computer or smart device via Wi-Fi or Bluetooth, check
the Wi-Fi LED or Bluetooth LED to see if they are connected properly.
Follow the steps below.
1
Close the roll paper cover.
2
While pressing the Feed button, turn on the printer. (Hold down the Feed but-
ton until printing starts.)
After printing the current print status, a continuing self-test guidance is printed, and the power
LED flashes.
3
Briefly press the Feed button (less than one second) to continue the self-test.
The printer prints using the built-in character set.
After "*** completed ***" is printed, the printer is reset and switches to standard mode.
