APPENDIX D: ADJUSTING THE PAPER ROLL NEAR-END SENSOR
LOCATION
The remaining detectable amount of paper on the roll paper varies with the inside and outside
diameters of the paper core. The minimum detectable amount of paper on the roll paper can be set
using the following method:
1) The inside diameter of the paper spool should be 12mm {0.47"} and the outside diameter of the
paper spool should be 18mm {0.71"}. Specified thermal paper should be used.
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.
Adjust the positioning plate to #1 if the outside diameter of a roll paper to be used is 18mm.
Adjust the positioning plate to #2 if the outside diameter of a roll paper to be used is more than
18 mm.
