Adjusting the Paper Roll Near-End Sensor

Below are two situations where a 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 the remaining amount of roll paper.
Follow the steps below to adjust the roll paper near-end detector.

 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.
 In order for the near end detector to correctly detect the amount of roll paper remaining,
use roll paper with a core inner diameter of 10.5 to 12.5 mm {0.41 to 0.49"}
When the printer is installed on a wall, the position of the near-end detector must be adjusted.
