The transport belt [A] is driven by the transport belt motor [B]. The transport belt
motor starts when the copier sends an original feed-in signal.
Inside the transport belt are five pressure rollers which give the proper pressure
between the belt and original. The pressure roller [C] closest to the left original
scale is made of rubber for the stronger pressure that is needed for thick originals.
The other rollers are sponge rollers.
Since the copier's original position is at the left rear corner, the original [D] fed from
the DF must also be at this position. But if the original was to be fed along the rear
scale [E], original skew, jam, or wrinkling may occur.
To prevent such problems, the original transfer position is set to 3.5 mm away from
the rear scale as shown. The 3.5 mm gap is compensated for by changing the
starting position of the main scan.
