B) Determining the position of the trays
The position of the tray is identified by the copier's DC controller PCB with
reference to the tray position signal from the tray position sensor (PS16).
The tray is considered to be at the home position when the trays are at the for-
ward position, and the vane on the traction gear blocks the sensor.
The home position is checked when the machine is switched ON.
