7.

The original is moved to the copyboard glass and then to the pickup assembly. When the pre-
registration sensor (U502) detects the leading edge of the original, the feed motor (M2) stops.

Figure 2-271

8.

The feed motor stops once, and starts to rotate clockwise. When the pre-registration sensor
(U502) detects the leading edge of the original (OFF), the feed motor (M2) starts to slow down.
The feed motor stops when the leading edge of the original reaches the image leading edge
position.

Figure 2-272

9.

When the original reaches a specific position, the reversal delivery motor (M3) rotates
counterclockwise for a limited time so that the reversal delivery flapper opens to switch the paper
path. The back of the original is then scanned.
