CHAPTER 1 GENERAL DESCRIPTION

2. Feeding Methods

There are 2 document feeding methods:
"continuous feeding" that continuously feeds
documents set on the document feed tray
with the pickup roller and "manual feeding"
that stops the pickup roller and manually
feeds one document at a time to the position
where the document is fed with the feed roller.
Continuous manual feeding mode is provided
to scan a batch of documents that cannot be
fed smoothly.
1) Continuous feeding
In continuous feeding, the documents that
are drawn with the pickup roller are fed
with the feed roller and separated with the
retard roller one at a time to avoid double
feeding.

2) Manual feeding
The [Bypass Mode] key lights and the
document feed tray lifts and one document
is fed at a time.
Since the pickup roller stops during manual
feeding, insert the document to the position
where it is pulled in with the feed roller.

Note: During manual feeding, documents are
not separated with the retard roller.
When multiple documents are set, some
of them may be fed together, causing a
document jam.
To scan bound multi-page documents
such as invoice booklets, face the bound
side to the feed inlet and scan with
"manual feeding".
Note: The [Bypass Mode] key is interlocked
with [Manual Feeding] of "Feed Option"
set with the ISIS/TWAIN driver.
When the [Bypass Mode] key on the
control panel is pressed, or "Feed Op-
tion" is set to [Manual Feeding], the
[Bypass Mode] key lights and the
document feed tray lifts.
