Check This Item
Is the inside of the ADF
dirty?
Is the document loaded
correctly?
Is the "Brightness (Black
and White scanning only)"
setting on [Option] of the
[Scanning] tab set to
extremely Light or Dark?
Are you scanning in color
mode, documents
including handwritten or
typed text, tables or frames
with ruled lines?
Does your PC meet the
recommended system
requirements?
Is the USB 1.1 connected?
Note: When using an
USB1.1 interface, the data
transfer rate may be
slower due to large data

Resolution
Clean the inside of the ADF following
the instructions in Chapter "8 Daily
Care" (page 227).
Load the document correctly
following the instruction in "3.3
Loading Documents" (page 49)
Adjust "Brightness" at [Scanning]
[Option] in the "ScanSnap Manager
Scan and Save Settings" dialog
box.
The color mode is used for capturing
colored images like photos in high
quality. For other documents
including textual content, select the
checkbox for [Setting for text only
document] at [Scanning]
in the "Scan and Save Settings"
window.
If it does not improve even after you
have tried this method, change
"Image quality" setting.
Confirm the system requirements in
"Before Installing the Supplied
Programs for the ScanSnap" (page
6).
Scanning speed will be slower
whenever the recommended CPU
and memory requirements are not

box, clear the checkboxes of the
following to increase the scanning
speed.
