Cause
Scanner memory is
insufficient.
You are using an invalid
version of Winsock.
The machine or client
computer is not connected to
the network correctly.
The network is crowded.
Solution
• Reset the scan size.
• Lower the resolution.
• Set with no compression. For
details about the settings, see
TWAIN driver Help.
The problem may be due to the
following:
• Scanning cannot be performed if
large values are set for brightness
when halftone or high resolution is
used. For details about the
relationship between scan
settings, see "Relationship
between Resolution and Scan
Size", Scan.
• If a misfeed occurs, you might not
scan an original. Remove the
misfeed, and then scan the
original again.
Install the operating system of the
computer or copy Winsock from the
operating system CD-ROM.
• Check whether the machine or
client computer is connected to
the network correctly.
• Disable the client computer's own
firewall. For details about firewall,
see Windows Help.
Wait for a while, and then connect to
the network again.
