c. Arching
The one-way clutch rotates idly as long as the pickup motor (M2) rotates in reverse, keeping
the registration roller at rest; the original is now butted against the registration roller so that
it will arch and is made free of moving askew.

d. Feeding
The pickup motor (M2) and the feed motor (M1) rotate in normal direction to cause the
registration roller and the read roller to move the original to the read standby point. At this
time, the pickup clutch is kept off to cut the drive from the pickup motor so that the pickup
roller will not move up. When the original reaches the read standby point, the pickup motor
(M2) and the feed motor (M1) stop to rotate.
