2.1.6 ORIGINAL TRANSPORT

[C]
B301D106.WMF
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 six pressure rollers which maintain the correct
pressure between the belt and original. The pressure roller [C] closest to the left
original scale is made of rubber for the stronger pressure needed for thick originals.
The other rollers are sponge rollers.
Normally, originals are manually placed at the left rear corner, so an original [D] fed
from the DF must also be at this position. But if the original is 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.
