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
Detects presence of roll paper and black marks.
• NE(Near End) Sensor
Detects whether the roll paper is nearing its end.
• Presenter Sensor (TUP592 Only)
Detects paper in presenter.
e aforementioned sensors can be adjusted as follows.
NE Sensor
1.1 Adjustment of the PE/BM Sensor
1. Turn the printer o and unplug the power cord.
2. Remove the screws. en, remove the board chassis.
3. Using the tip of a ballpoint pen or a similar object, set the DIP switches as follows: DSW1-4 OFF, DSW1-5 ON.

4. Set ordinary paper that is not used for black marks, in the PE/BM sensor unit shown below.
Use the release lever to open the platen unit (the TUP592 includes presenter unit), insert the paper from the paper
insertion inlet and then close the platen unit to set the paper.
5. Turn the power on. e LED on the control panel will ash two times, then the printer will enter the PE/BM sen-
sor adjustment mode.
6. Use a small regular screwdriver to slowly turn the VR1 clockwise, as shown in the drawing below. Adjust this to a
position where both LED1 (green) and LED2 (red) light.
7. Turn the power OFF.
8. Turn the DIP switch DSW 1-4 and DSW 1-5 to its original setting.

4. Set unused roll paper that will actually be use.
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.

on the control panel will ash two times, then the printer will enter the presenter sensor adjustment mode.
6. Use a small regular screwdriver to slowly turn the VR3 clockwise, as shown in the drawing below. Adjust this to a
position where both LED1 (green) and LED2 (red) light.
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.
2) Each time the printer enters the presenter paper detection sensor adjustment mode, this
adjustment is necessary.
3) There is a point where the LED ashes instantly. That is not an adjustment position.
There is a point where the LED lights completely. That is the adjustment position.
