1
Open the roll paper cover, and remove the roll paper.
2
Loosen the adjustment screw fastening the sensor, and align the upper
edge of the positioning plate with the adjustment position.
3
Tighten the adjustment screw.

After adjustment, make sure that the detection lever operates smoothly.
•
Since roll paper cores vary slightly in shape, depending on paper roll design and
manufacturing tolerances, it is 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 sensor can detect the remaining paper as accurately as possible.
