1)
LED circuit
This circuit is composed of the paper rear edge sensor
(FPPEND) on the inner punch circuit and the light emitting
(LED) circuit of the paper horizontal resist sensors (FPPD1 –
6) circuit.
Turning ON/OFF of LED1 – 7 are controlled by the paper rear
edge sensor (FPPEND) and the paper horizontal resist sen-
sors (FPPD1 – 6) circuit.

(LED) circuit of the paper horizontal resist sensors (FPPD1 –
6) circuit.
Turning ON/OFF of LED1 – 7 are controlled by the paper rear
edge sensor (FPPEND) and the paper horizontal resist sen-
sors (FPPD1 – 6) circuit.
2)
Photo transistor (PTR) circuit
This circuit is the light receiving (PTR) circuit of the paper rear
edge sensor (FPPEND) and the paper horizontal resist sensor
(FPPD1 – 6) circuit on the inner punch circuit. When light is
received from the LED, the collector signal flows through PT1
– 7.
