6. Adjusting the Sensor
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.
6-1. Adjusting the Near End Sensor Position
Use the following procedure to adjust the near-end sensor so it is compatible with the size of
paper roll you are using.
However, for vertical or wall-mount use, keep the adjuster xed to level 3, without changing
its position.
Open the printer cover.
Determine the diameter of the paper roll you are using and nd the required setting in the
table below.
Insert the tip of a ballpoint pen or similar object into the hole of the adjuster, and then push
and side the adjuster to the desired setting.
When changing the setting, make sure that the position of the hole is aligned with the align-
ment mark indicated by the arrow.
