Are there any debris on the
document feeding path?

feeding path.

problem, refer to "Clearing Document Jams"
(page 302).
Do the loaded documents (e.g.
business cards or postcards)
satisfy the required size
conditions?
If not, they might not pass
smoothly through the ADF.
Try the following:
• Slightly push through with your finger the
first sheet of the documents at the start of
scanning.
• Change the insertion direction of the doc-
ument.
Are you scanning documents
with a different [Paper size]
setting?
Select the [Paper] tab → [Paper size] on the
ScanSnap setup dialog box/window, and
specify the correct paper size for scanning.
Did you load any paper that is
thin, torn, or bent?
When scanning a document that is hard to
feed, load it sheet by sheet or use the Carrier
Sheet.
The ScanSnap is not
recognized even if
ScanSnap Manager
is installed.
Did you connect the ScanSnap
to your computer before
installing ScanSnap Manager?
Is the ScanSnap registered as
[Other Device] or [Unknown
Device] in [Device Manager]?
Select the [Start] menu → [Control Panel] →
[System and Maintenance] → [Device
Manager].
Delete the device name such as USB device
(which differs depending on the operating
system) under [Other Device] selection in the
[Device Manager], and restart your
computer.
The file size of a
scanned black &
white image is the
same as that of a
scanned color
document image.
Is the black & white document
scanned in color or gray mode?
Select the [Scanning] tab from the ScanSnap
setup dialog box/window and change the
setting for [Color mode] to [B&W].
Color documents are
not scanned as color.
Documents in a dark color close
to black, such as dark green,
may be scanned as black and
white or gray.
Select the [Scanning] tab from the ScanSnap
setup dialog box/window and change the
setting for [Color mode] to [Color].
