Adjusting the Roll Paper Near-End Sensor Below are two situations where a roll paper near-end 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 roll paper design and manufacturing tolerances, it is impossible to detect the remaining paper exactly.  Use roll paper with a core whose inner diameter is 12 mm {0.47"} and outer diameter is 18 mm {0.71"} so that the near-end sensor can detect the remaining paper as accurately as possible. Follow the steps below to adjust the roll paper near-end sensor. 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. Adjustment position Upper Lower (Initial setting) Remaining amount of paper (outer diameter: mm) Approx. 27 {1.06"} Approx. 23 {0.97"} 70
