1. Original set detection
The original is detected by the single feed set sensor [A] when the original is
set on the single feed table.
2. Size detection
The original width is detected by the single feed original width sensor [B]
under the rear original guide [C]. Moving the guide changes the value of the
sensor. (The sensor is a potentiometer.) The front original guide [D] and rear
original guide are moved by the racks [E] and pinion [F] at the same time. As
the original length sensor is not used for the single feed mode, the original
length is not detected. When the B4 or LG original is set on the single feed
table, the original size is determined by the machine version.
(U.S.A. version machine ... LG, Europe version machine ... B4).
