Possible Solution
Make sure that:
• the host computer meets minimum requirements
for scanning.
• there is enough free space on the hard disk drive.
• all other applications are closed.
• the USB connection is 2.0.
You can also try changing the scanning options
(compression, etc.) in your scanning application.
Make sure that:
• the leading edges of all batched documents are
centered in the automatic document feeder so
that each document will come in contact with the
feed rollers.
• the feed module and separator module are clean
and not worn.
• documents with an unusual texture or surface are
fed manually.
Clean the feed module, separator module, and drive
rollers. See "Maintenance" on page 71 for details.
Clean the imaging guides. See "Cleaning the
Imaging Guides" on page 86 for details.
