Step 61:
Paper feed motor (DFM) reverse rotation
(Resist roller rotation)
The original is sent to the transport section.

END
Note: * A: For the first original, the preliminary paper feed opera-
tion is performed.
* B: When there is an original on the original tray in ad-
vance, it is discharged.
* C: When there is no original on the original tray, move up
the weight plate and the stopper.
* D: When there is no original on the original tray, the
original set sensor (DSS) output becomes LOW.
* E: It depends on whether there is any preliminary fed
original in step 38 ∼ step 44.
