The ADF detects the original size by combining the readings of original length sensor [A], and original width
Original Length
The original length sensor and the disk [E] (connected to the transport roller) generate a pulse signal. The CPU counts pulses, starting when the leading edge of the original turns on the registration sensor [F], until the trailing edge of the original turns off the entrance sensor [G].
Original Width
The CPU detects original width using three original width sensors
