Adjusting the sensor
The angle of the sensors has already been adjusted when the unit
is shipped. But, if the Sensor light on the control box is flashing,
you need to adjust the sensor so that the light detector is aligned
with the light emitter. When they are aligned, the Sensor light
comes on.

Caution:
❏ Avoid placing the sensor in direct sunlight; otherwise, the
auto take-up reel unit may not operate properly.
❏ Prevent fans or air conditioners from blowing directly on the
roll paper. If the paper is blown out of the sensor area, it will
not be taken up properly.
To adjust the sensor position, follow the steps below.
