Process of detection of original size

1) When the equipment is in the original size detection mode, contact image sensor unit (CIS) is set at
its home position.
2) When the platen cover is opened, the sensors receive the light reflected from the original and if one
of the matrix conditions shown in 4) for original sizes are met, the size of the original is instantly
detected.
3) The output signal from each sensor is input to ASIC on the MAIN board to determine the size of the
original.
