A229 SM
2.1.6 ORIGINAL SIZE DETECTION
The DF detects original width using three original width sensors-1 [A], -2 [B], -3 [C],
and detects original length using entrance sensor [D] and registration sensor [E].
The CPU counts the feed-in motor pulses between when the leading edge of the
original turns on the registration sensor and when the trailing edge of the original
turns off the entrance sensor.
The machine detects the original size from the combination of readings from all
sensors.
