CHAPTER 2 OPERATIONS
G. Pre-Reversal Pickup/Delivery
1.
Outline
The operation referred to as "pre-reversal" is used to reverse a double-sided original in advance
when moving it to the copyboard glass.
Pre-reversal pickup/delivery operation takes place when copying small-size double-sided origi-
nals, and its reading mode is always fixed reading.

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 registration roller and the reversing roller are driven to reverse the original in advance.
The first original is moved by the reversing roller for a specific length after its trailing edge has
moved past the pre-registration paper sensor (S2), and is stopped.
