Check The Item Out
Are you scanning docu-
ments including typed text,
tables with ruled lines, or
handwritten text in color
mode?
Does your computer satisfy
the recommended system
requirements?
Is the scanner connected
via USB 1.1 port?
Note: If USB 1.1 port is
used, scanning speed may
be very slow when a large
amount of data is trans-
ferred.
Is the Pad ASSY dirty?
Is the Pad ASSY worn?
Is the document stack
thicker than 0.2 in. (5mm)?
Resolution
The color mode is used for capturing color
images such as the photo in high quality. For
other documents including textual content,
mark the "Setting for text only document"
checkbox, which is in the "Read Mode Option"
window, which can be opened by clicking the
[Option] button on the [Scanning] tab of the
"Scan and Save Settings" window.
Confirm the system requirements, referring
"Before Installing ScanSnap Manager" (page
6).
Scanning speed will slow down if the recom-
mended CPU and memory requirements are
not met.
If this is the case, in the "Scan and Save Set-
tings" window, select the [Scanning] tab, click
the [Option] button, and then clear the follow-
ing checkbox in the "Read Mode Option" win-
dow to increase the scanning speed.
