2-2-9. Print Head Error
If abnormal heat generation is detected at the print head for any reason, the print head drive power and the
paper feed motor drive power are shut down. In this case, shut down the printer immediately.
2-2-10. Motor Error
If you print continuously or feed paper continuously, the paper feed motor temperature will rise. If it exceeds
80
°
C, printing or paper feed will stop. When it is cooled to 70
°
C or lower, the error will automatically be reset.
However, the standard model is not equipped with a thermistor as well as such temperature control because
no heat generation exceeding 80
°
C as well as no smoking or ignition was observed with continuous printing
or paper feed at the fault test.

printer immediately.
