APPENDIX B: ADJUSTING THE ROLL PAPER NEAR-END SENSOR
LOCATION
•
The remaining detectable amount of paper on the roll of paper varies depending on the inside and
outside diameters of the paper core. The minimum detectable amount of paper on the roll of paper
can be set using the following method:
1) Use roll paper with the inside diameter of the paper core of 12 mm {0.47"} and the outside
diameter of the paper core of 18 mm {0.71"}. Use the specified thermal paper.
2) Loosen the adjusting screw that holds the paper near-end sensor and set the top of the positioning
plate to the appropriate adjustment value and tighten the adjusting screw.
•
Dimension “A” to be detected is different for the detecting position of the near-end sensor and the
thickness of the roll paper core.

NOTES: 1. Since the specified thermal paper dimension of the outside diameter of roll paper in
Table B.1 is a calculated value, there may be some variations depending on the printer.
2. If the end of roll paper has a red end mark, the end mark may lift up all of the roll paper.
In this case, the remaining roll paper as measured by A in Table B.1 cannot be obtained.
3. Be sure that the detection lever operates smoothly after you finish the adjustment.
4. The paper quality may cause the roll paper to become loose and result in incorrect
detection may result.
