5-2-2 Adjustment Near-End Sensor
This sensor has five settings, which are scale #1,2,3,4 and 5. The NEAR END SENSOR is set to #3 position at the factory.
You can change the setting to Adjustment scale #1,2,3,4and 5 as described below.
1. Open the PRINTER COVER.
2. Change the setting to the scale #1,2,3,4 and 5.
3. If you find that there is too much paper remaining on the roll paper when the NEAR END SENSOR is triggered.
Pull it down to scale #1 or #2. Otherwise push the KNOB PAPER END up to scale #4 or #5 as illustrated figure 5-3.
The accuracy of the NEAR END SENSOR depends on the Adjustment Scale setting and the roll paper Winding Core
Diameter. The NEAR END SENSOR is set at Adjustment Scale #3. This is the appropriate scale for the recommended
paper thickness.
Note: The factory setting is based on roll paper core with an outside diameter of 18mm.
