This printer is equipped with the following two paper sensors:
• PE and BM (Paper End and Black Mark) Sensor
Detects whether a roll paper is loaded in the printer.
In addition, detects the Black Mark that is pre-printed
on the paper’s print side.
• NE (Near End) sensor
Detects whether the roll paper is nearing its end.
