6.6.6 ORIGINAL SIZE DETECTION

The ADF detects the original size by combining the readings of original length
sensor [A], and original width sensors-1 [B], -2 [C], and -3 [D].
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 -1, -2, -3 as
shown above. Three small circles on the diagram indicate the positions of the
sensors.
