Q: The OneTouch feature is not working with my scanning program.

A: The one touch function only works with programs that are OneTouch compliant, like Presto Pagemanager, Windows 98 Imaging and Photoshop 5.0 Full Edition. These applications support linking scanner events with the Start button on Windows 98 and enable the scanner monitor utility.

Q: My scanner software doesn't work properly.

A: Check your system requirements. See if the system requirements, such as the operating system version, are correct for your software. Check your computer's memory. See if the computer has enough memory for your software. If you're running other software at the same time, using RAM resident programs, or have many device drivers, the computer may not have enough memory. (See your software and computer manuals.) If you are scanning a large image or scanning at a high resolution, your computer may not have enough memory to process the image. Check your software installation. Make sure that your software is correctly installed and set up. If all else fails, uninstall your software, then reinstall it.

Q: My system doesn't recognize the USB port (Windows 98 only).

A: The USB interface is not supported by Windows 95 (including OSR-2.x) or Windows NT, you must have Windows 98 preinstalled full edition. The scanner must be connected to a built-in (root) hub or first tier hub only. If the scanner is attached to a built-in root hub and the scanner isn't recognized, check the computer's user manual and to see if the USB port needs to be enabled in the computer's setup. If the scanner is attached to a first tier hub, that hub must be self-powered (ie: an AC adapter should be attached). Be sure to use the USB cable that came with your scanner. Turn off both the scanner and your computer. Then turn on your scanner before you turn on the computer. If you're connected to a USB hub, try connecting the cable to the computer's USB port.

 
Q: Can the Expression 1600 be turned off? The system hangs up (Windows only) when I turn the scanner off.

A: Yes, the Expression 1600 can be turned off while the computer is on. Because USB is Plug and Play, the system will find the scanner when it is reconnected and powered on. If your system hangs after turning off the scanner, try disabling Event Monitoring in Scanners and Cameras first.

Q: Can the Expression 1600 scanner be disconnected from the computer after installing the scanner software (Macintosh only)?

A: The scanner monitor searches for the Expression 1600 during start up and may cause your system to hang if it does not find it. Do not disconnect your scanner unless you disable the Epson Scanner Monitor extension in the Extensions folder.

Q: What is the fastest way to connect the Expression 1600 scanner to a Macintosh or PC?

A: Depending on which interface your system supports, all models of the Expression 1600 can be connected via its standard USB port or for faster throughput, a SCSI interface can be used. The newest method is the optional IEEE-1394 (FireWire) scanner interface. Firewire is only compatible with blue and white PowerMac G3, G4 and DV-iMac.

Q: Can the Expression 1600 be networked?

A: Yes, it can be used across networks in a mixed platform workgroup by both Macintosh and PC users. Scan Server can only be installed on a PC. If you have an all Mac network, you will need to configure a PC system as your server.

Q: Why can't I start Epson TWAIN Pro Network from a client computer?

A: Make sure the scanner is turned on and the scan server is running on the desktop. Make sure the cables connecting the scanner to the scan server host are properly connected. Make sure the correct IP address for the scan server is entered in the Epson TWAIN Pro Network setup window for the client station. Make sure the scan server host and TWAIN client station can communicate with each other using the TCP/IP protocol. (i.e. pinging each station). Make sure the network interface card is installed correctly  in both the scan server and the client computer. Make sure both the scan server and client computer are running the TCP/IP protocol. If more than one scanner is connected to the scan server, make sure the Expression 1600 is selected as the default scanner.
