1. Sensor Adjustment
Presenter Sensor
is printer is equipped with the following three paper sensors: PE/BM Sensor
• PE(Paper End)/BM(Black Mark) Sensor

5. Connect the AC adapter and turn the power switch on while pressing switch SW2 on the control panel. e LED
on the control panel will ash two times, then the printer will enter the NE sensor adjustment mode.
6. Use a small regular screwdriver to slowly turn the VR6 clockwise, as shown in the drawing below. Adjust this to
a position where both LED1 (green) and LED2 (red) light. If it is not possible to adjust to a position where both
LED1 (green) and LED2 (red) light, adjust to a position where LED1 (green) is extinguished and LED2 (red) is lit.
Note: When tilting the unit, be careful that the paper does not fall out.
7. Turn the power OFF. Turn the DIP switch DSW 1-4 and DSW 1-5 to its original setting.

If the position where both LED1 (green) and LED2 (red) light, turn VR3 clockwise slowly to adjust to a position
where both LED1 (green) and LED2 (red) light.
Note: 1) When adjusting, always rotate clockwise.
If rotated in the other direction, accurate adjustment is not possible.
