6.11.1. Drum Sensor
This Switch detects whether the DRUM unit is set or not.
When there is the unit, the input signal of IC300-K32pin becomes low level.
When there is not the unit, the input signal of IC300-K32pin becomes high level.
When there is the unit, the input signal of IC300-K32pin becomes low level.
When there is not the unit, the input signal of IC300-K32pin becomes high level.

6.11.2. Paper Sensor
This Switch detects whether there are recording papers in the paper tray #1 or not.
When there are recording papers in the tray, the input signal of IC300-M31pin becomes high level.
When there no recording papers in the tray, the input signal of IC300-M31pin becomes low level.
When there are recording papers in the tray, the input signal of IC300-M31pin becomes high level.
When there no recording papers in the tray, the input signal of IC300-M31pin becomes low level.
6.11.3. ADU Jam Sensor
This sensor detects whether the paper is at the ADU sensor position.
When the recording paper is detected, the shelter plate lets the sensor light pass.
So the photo-transistor turns on and the input signal of IC300-F33pin becomes low level.
When the recording paper is not detected, the shelter plate closes the sensor light.
So the photo-transistor turns off and the input signal of IC300-F33pin becomes high level.
