Dip Switch and Paper Near End Settings A-7
Adjusting the Paper Near End Sensor
The paper near end sensor detects when paper is almost gone by
measuring the diameter of the paper roll. The sensor has two
settings.
Because of variations in paper roll cores, it is not possible for the
sensor to measure exactly the length of paper left on the roll when
the sensor is triggered. Of the two settings, the factory setting
(lower) leaves the least amount of paper on the roll when the
sensor is triggered. If you want more paper left, chang e the setting
as described below.
Note:
The factory setting is based on a paper roll core with an outside
diameter of 18mm and an inside diameter of 12mm. If you use a
paper roll with a core with an outside diameter of more than 18mm,
it is better to change to the upper setting, as described below.
1. Open the paper roll cover, and remove the paper roll.
2. Loosen the adjusting screw and move the tab up to the upper
setting.
3. Tighten the adjusting screw, and check to be sure that the
detecting lever moves freely.
4. Replace the paper roll.
