3.9.1 Sensors and LED indicators

1) Paper roll near-end sensors
The paper roll near-end sensor is located on the roll paper supply device. It detects the near-end
of the paper roll by sensing the paper roll diameter. When the paper roll diameter becomes
sufficiently small, the RECEIPT OUT indicator lights.
2) Paper roll sensors
The paper sensors is located in the paper path. It detects the presence of paper from the paper
roll in the paper path, then loads paper from the roll. When there is no paper in the path (paper
end status), the RECEIPT OUT LED indicator lights.
3) Slip insertion sensor
The slip insertion sensor is located in the slip paper path and detects the presence of slip paper in
the paper path. The SLIP LED indicator lights accordingly.
4) Slip ejection sensor
The slip ejection sensor is located in the slip exit and detects the removal of the slip paper. The
printer does not proceed to the next operation until the paper has been removed. (The SLIP LED
indicator remains blinking.)
