Document Feeding Overview
The duplexing automatic document feeder (DADF) scans single or multi-page documents auto-
matically. Single-sided and double-sided documents can be fed. Mixed sizes can be run after
the appropriate selections are made on the UI
The DADF can invert a document to scan images on both sides, and it employs a constant
velocity transport (CVT) system. With the CVT system, the lamp carriage of the IIT is fixed at a
specified position (the scan position) where images are scanned as documents feed across the
platen at a constant speed. Refer to Figure 1.
Figure 1 DADF
The DADF performs the following functions:
• Automatically separates and feeds documents for copying.
• Automatically senses the document size.
• De-skews the documents before they are copied.
• Automatically inverts two-sided documents for duplex copying.
• Automatically stacks copied documents on the exit tray in the correct order and same ori-
entation in which they were fed.
