Chapter 2 Setup 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. • 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. 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. 2 3 Tighten the adjustment screw. 4 After adjustment, make sure that the detection lever operates smoothly.
