2.3 Adjusting the Roll Paper Near-End Detector
Below are two situations where a roll paper NE detector adjustment is required.
❏ To adjust the detection position to suit the diameter of the roll paper core used.
❏ To adjust the detection position of remaining amount of paper.
Note:
Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing
tolerances, it impossible to detect the remaining paper exactly. Use roll paper with a core inner diameter of
12 mm {0.47"} and outer diameter of 18 mm {0.71"} so that the NE detector can detect the remaining
paper as accurately as possible.
Follow the procedure below to adjust the roll paper NE detector position.
1. Open the roll paper cover, and remove the roll paper.
2. Loosen the adjustment screw fastening the detector, and align the upper edge of the
positioning plate with the adjustment position. Adjustment positions are as follows:

Note:
The adjustment screw is set to the lower position before shipment.
3. Tighten the adjustment screw.
4. After adjustment, make sure that the detection lever operates smoothly.
5. Load the roll paper.
6. Close the roll paper cover.
