Notes:
1. The near-end sensor unit cable should be long enough for combination with the other
optional parts. If you change the layout or use the optional parts. remove the cable band.
Also, be careful when removing the cable not to damage its insulating cover.
(4) Residual Paper Amount (For Reference):
The residual amount to detect is adjusted by moving the near-end sensor unit in the roll paper
diameter direction. See the following table regarding the roll paper that is detected by the near-end
sensor.
Also, see Fig. 8.4.2.A. for the applicable reference position.

5. If the detector is affected by external light distrubance, there are cases where a near-end
is detected before reaching the set detection diameter. Therefore, design the frame so that
the printer is unaffected by this light when this printer is used by being incorporated in a
frame designed by the end user.
