Adjusting The Paper Roll Near-End Sensor - Epson TM-H6000V Technical Reference Manual

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.

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.
