Paper Near End Sensor
This sensor is located on the roll paper holder on the receipt side and the journal side.
When the winding diameter of the roll paper becomes small, it is indicated by the ERROR
indicator. Since the amount of roll paper remaining may differ depending on the thickness
of the winding core, the near end sensor can be set so as to correspond to the thickness of
the winding core.
Setting Method
1. Loosen the adjustment screw holding the sensor lever.
2. Set the top end of the sensor lever on the correct step on the adjustment scale.
When the specified paper with a winding core whose outer diameter is ø18 mm and
inner diameter is ø12 mm is used, the approximate adjustment scale step are as fol-
lows. The factory default setting of the scale is lowest position.
• Dimension T, corresponding to the step on the adjustment scale, may vary some-
what.
3. Tighten the adjustment screw and close the sensor lever.
Check if the sensor lever is operating smoothly.
