Document Feeding Methods

Two document feeding methods are available: continuous feeding,
which feeds documents automatically from the Document Feed Tray
by the pickup roller; and manual feeding, which requires manually
feeding one document at a time for transport by the feed roller, while
the pickup roller is disabled.
Selecting the Document Feeding
Method
Continuous Feeding is the default feeding method. However, for the
one-by-one page feeding, manual feeding can be enabled by
selecting [Manual Feeding] as the [Feeding Option] in the ISIS/TWAIN
driver, or [Separation Off] with the User Mode. Continuous manual
feeding is also provided as way to scan a batch of document pages
that cannot be automatically fed.
Continuous Feeding
With Continuous Feeding, documents loaded in the Document Feed
Tray are picked up automatically by the pickup roller and transported
by the feed roller, while the retard roller separates each page to avoid
double feeding
Manual Feeding
The Document Feed Tray is raised so that documents can be fed
manually one sheet at a time.
For manual feeding, you need to insert each document page far
enough to be pulled in by the feed roller (because the pickup roller is
disabled).
