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.
1
Make sure the power supply is disconnected.
2
Open the roll paper cover, and remove the roll paper.
3
Loosen the detector adjustment screw with a coin or similar tool.
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.
