9.2.2 Moving Down the Original Pickup Roller and Moving Up the Original
Stopper
The original pickup roller is kept in up position during standby, thereby ensuring a gap
used to accommodate a stack of originals. The original stopper is kept in down position dur-
ing standby to prevent the original from sliding too far inside the machine when it is placed.
When the ADF motor (M3) rotates counterclockwise to start original pickup operation,
the drive of the timing belt moves down the original pickup roller and, at the same time, the
original stopper starts to move up, causing an original to be picked up and sent inside the
machine.
