Using the 4000 ED with Other Devices
When using the 4000 ED with other devices connected to the same IEEE 1394 (Firewire) bus:
Do not turn other devices on or off or disconnect interface cables while scanning is
in progress (i.e., while the scanner status LED is blinking slowly).
Connect the scanner directly to the computer. The scanner may not function as
expected when connected to an IEEE 1394 hub.
The scanner may not function as expected when operated at the same time as other
IEEE 1394 devices. Should a problem occur when the scanner is used with other IEEE
1394 devices, disconnect all IEEE 1394 devices, including the scanner, and then re-
connect the scanner.
Only one scanner can be connected to the computer at a time.
Using the COOLSCAN IV ED with Other Devices
When using the COOLSCAN IV ED with other devices connected to the same USB port:
Do not turn other devices on or off or disconnect interface cables while scanning is
in progress (i.e., while the scanner status LED is blinking slowly).
Connect the scanner directly to the computer. The scanner may not function as
expected when connected to a USB hub.
The scanner may not function as expected when operated at the same time as other
USB devices. Should a problem occur when the scanner is used with other USB
devices, disconnect all USB devices, including the scanner, and then reconnect the
scanner.
Only one scanner can be connected to the computer at a time.
Connecting the Scanner
Although this manual instructs the user to turn the scanner off before connecting the interface cable, IEEE
1394 cables can be connected while the scanner and computer are on and the scanner used immediately
following connection. There is consequently no need to turn the scanner off every time the cable is
connected or disconnected. You should, however, leave a few seconds between disconnecting and recon-
necting the cable.
