* At the time of shipment, pins 2 and 3 are short-circuited by JP5 and paper detection is
disabled (always paper present is defined). In actual use, purchase the above connector.
4.6.2 Reference Circuits
* In the above circuit, reflection type photo interrupter is taken as an example. With the above
sensor, the clearance from paper must be about 1 mm. As electric characteristic varies with
the sensor used, understand the sensor before use.
* Voltage detection range at the control board side (across 2 and 3) is.
0 ~ 0.4V: Paper Present
1V or more: No Paper
This is not warranted in the state other than the above.
