Problems and Solutions
If you’re having problems, this section answers some of the most common questions.
For additional software troubleshooting tips, see your electronic EPSON Expression
1680 Reference Guide.
Setup Problems
Your system doesn’t recognize the
scanner
or
EPSON TWAIN Pro (or EPSON
TWAIN Pro Network) doesn’t
appear in the list where you select
your scanner.
■
Check your cable connections.
If your cable is securely
connected to both the scanner
and computer, try another
cable. If you have a USB
connection, use an EPSON
USB cable. If you have a SCSI
connection, use a high quality,
shielded SCSI cable, and be sure
to restart your computer after
you change the cable.
■
The USB connection only
supports a Macintosh,
Windows 98, Windows 2000 or
Windows Me system. The
Windows operating system
must be preinstalled on your
system, not upgraded. There is
no USB support for Windows
95 or Windows NT.
■
Make sure your scanner is on. If
you opened your host
application before you turned
on the scanner, close your
application and reopen it. Also,
try restarting your system.
■
If your scanner is connected to a
USB hub, try connecting it
directly to the computer’s USB
port.
■
Check the Plug and Play option
for your computer; it should be
active (Windows 95, 98, 2000
and Me only).
■
If you have a SCSI connection,
turn off both your scanner and
computer. Then turn on your
scanner before you turn on the
computer.
■
If you have a SCSI connection,
make sure your SCSI board is
installed correctly.
■
If the SCSI board is found, but
not the scanner, check the SCSI
terminator and ID. Make sure
the SCSI ID doesn’t conflict
with another SCSI device.
