A. Detecting the width of the original 1
• The width of the original will be detected by the restriction plate positional volume under
the document feed tray.
• Reference for setting the original on the document feed tray is its center.
B. Detecting the width of the original 2
• Three consolidation sensors are mounted to where the paper passes immediately after it
is fed. It is for detecting the width of the original for mixed original/AMS.
C. Detecting the length of the original 1
• The length of the original will be detected by the length sensor/1/2/3.
• Length sensor/1 and /3 are mounted in this order with the length sensor/2 being closest
to the feed roller.
D. Detecting the length of the original 2
• Length of the mixed original/AMS will be calculated by the time before read sensor is
interrupted.
