(1) Document feed, transport, scan, paper exit, and
operating speed
The document fed by the take-up roller is sent through the paper feed
roller and the transport roller to the resist roller section.
In the resist roller section, the document lead edge and the scan start
position are synchronized. The document is transported to the scan
section. After being scanned, the document discharged to the docu-
ment exit tray by the paper exit roller.
The document transport speed varies depending on the scan mode
and the scan magnification ratio as shown below.
