Adjusting the Paper Roll Near-End Sensor
Below are two situations where a roll paper NE sensor 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.
Follow the steps below to adjust the roll paper near-end detector.
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.
4
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.
