Appendix D: Adjusting The Paper Roll Near-End Sensor Location - Epson TM-U925 Manual

APPENDIX D: ADJUSTING THE PAPER ROLL NEAR-END SENSOR
LOCATION
The remaining detectable amount of paper on the paper roll varies with the inside and outside diameters
of the paper core . The minimum detectable amount of paper on the paper roll can be set using the
following method:
1) The inside diameter (fd) of the paper spool should be 10mm (.394") or more.
2) Set the paper roll diameter A to obtain the corresponding adjustment position from the table below.
Figure D.1 Paper Roll Spool
NOTES: 1. Since diameter A corresponding to the adjustment position in the table is calculated from
standard measurements, there may be some variations depending on the printer.
2. If a paper roll with a red end mark at the paper end is used, the mark may cause the
paper to stick together. If this occurs, diameter A differs from the values in the table.
3. Be sure that the adjustable slider operates smoothly after finishing the adjustment.
4. If the paper on the paper roll becomes loose due to the paper quality, the paper roll near-
end sensor may operate incorrectly.
