Operation

1] The first original is picked up, and its leading edge is butted against the registration roller to
remove the skew. (For details of pickup operation, see D. "Original Pickup/ Separation" on
p. 2-24.)
2] The reversing roller and the feeding belt are driven to move the original.
The first original is moved for a specific length by the feeding belt after its trailing edge has
moved past the pre-registration roller paper sensor (S2), and is stopped.
