Cassette pick-up sensor
This is a photo-interrupter-type sensor. When paper supplied from the cassette, the sensor light is blocked by the sensor arm, thus detecting paper.
Cassette cam sensor
This is a photo-interrupter-type sensor. When the cassette camp rotates to block the sensor light, lowering of the pressure plate of the cassette is detected.
Cassette encoder sensor
The cassette encoder sensor detects the slits on the encoder film during cassette motor rotation, thus detecting the amount of rotation of the roller.
