Error Description Recovery
Head temperature error Head temperature exceeded the
proper range.
The printer recovers from the error when the head
temperature drops.
Cover open error in the
middle of printing
The roll paper cover was opened
during printing
The printer recovers from the error when the roll
paper cover is closed.
Error Description Recovery
Autocutter error The cutter blade is locked due to a
foreign object fell inside the printer
or other reason.
Remove foreign objects or paper, and then close
the roll paper cover to make the printer recover
from the error.
The printer automatically recovers from the error
if the blade can be unlocked easily, however,
make sure to check for foreign objects before use.
Instead of closing the roll paper cover, you can make the printer recover from the error using a
dedicated command, however, doing so will cause the printer to go offline due to a cover open error.
If an unrecoverable error occurs, turn off the power immediately by pressing and holding the
power button until the power LED flashes or by unplugging the DC cable or power plug.
