Problems you may have while using the scanner often involve the operation of your software and computer. Operation problems usually occur because of:

• Incorrect setup of the interface
  (See "Setting Up the Scanner" on page 2-1 of the Setup Guide.)

• Incorrect setup of your computer or software
  (See the Setup Guide.)

• Incorrect operation of your software
  (See "Optimizing Scanning" and "Understanding EPSON TWAIN Pro Features" in this guide. Also see Chapter 4 of the Setup Guide, "Using Your Scanner" on page 4-1.)

Also see the documentation that came with your computer and printer for possible solutions.

The READY light does not come on.

• Press the operate button to turn on the scanner.

• Make sure the power cord is connected to the scanner and is plugged into a power outlet.

The scanner does not scan.

• Wait until the READY light stops flashing and remains on (ready for scanning).

• Make sure your interface port and software settings are correct. Also make sure that your computer's interface board is installed properly.

• For SCSI interface users, make sure the scanner's SCSI ID and terminator are set correctly. See your Setup Guide for details on making these settings.

• For SCSI interface users, if you have other expansion boards in your computer, make sure that their interrupt settings are not interfering with your SCSI board. See your computer's documentation for details.

• For USB interface users, try connecting the scanner directly to the computer's USB port, or use an EPSON USB cable.

• For USB interface users, try connecting your scanner to a different port on your hub, or to a different hub.

• For Macintosh and IEEE 1394 interface users, make sure that the following Extensions are selected in the Extensions Manager: EPSON FW Scanner Enabler; EPSON FW Scanner Expert; and EPSON FW ScannerLib.

The scanner software does not work properly.

• Make sure your software is installed correctly.

• For Windows Millennium Edition, 98, and 2000 users, check if your scanner is listed more than once in the Scanners and Cameras Properties dialog box. To view the dialog box, click Start, point to Settings, click Control Panel, then double-click the Scanners and Cameras icon.

If EPSON Expression1680 appears more than once in the list of installed devices, follow the instructions in "Uninstalling the Scanner Software for Windows" on page 3-49 of the Setup Guide to remove it completely from the dialog box. Then follow the instructions in "Installing EPSON TWAIN Pro for Windows" on page 3-6 of the Setup Guide to reinstall EPSON TWAIN Pro.

• Make sure your computer meets the memory and other system requirements specified for the software you are using.

• Make sure the computer has enough memory for your software. If the computer does not have enough memory available, see your software and computer documentation for information on adding more memory.

The scanner cannot be selected or is listed as unavailable in Windows.

• Turn off the scanner and PC, and check that they are connected properly.

• Make sure that a scanner supported by EPSON Scan Server and EPSON TWAIN Pro Network is connected to the scanner server PC.

• For Windows Mellinnium Edition, 98, and 2000, make sure EPSON TWAIN Pro is installed on the scanner server PC (the PC which is connected to the EPSON scanner).

If you want to scan using the scanner server PC, make sure EPSON TWAIN Pro Network is installed on the PC.

• When connected using the SCSI interface, change the scanner's SCSI ID number to one that is not being used by any other SCSI device.

Note for Windows 98 users:

Depending on your Windows 98 version, you may have to uninstall the scanner from your system before changing the SCSI ID number. For instructions, see "When changing the ID number or replacing the SCSI board in Windows 98" on page 2-15 of the Setup Guide.

• Check the SCSI connection sequence and make sure the scanner's terminator switch is set correctly. The terminator switch should be set to ON when the scanner is connected directly to the computer, or when it is the last device in a daisy chain. For more information on setting the terminator switch, see your Setup Guide.

Scanning does not start by pressing the Start button.

• For Windows 95, NT 4.0, and Macintosh users, make sure the Scanner Monitor software is running.

• For Windows Millennium Edition, 98, and 2000 users, click the Events tab in your scanner's Properties dialog box and make sure the Disable device events check box is clear. Also make sure that the Start Button is selected as the Scanner events option, and that at least one application in the Send to this application box is selected. See Overview of Start Button Features for details.

EPSON TWAIN Pro does not start.

• Turn off the scanner and computer and check that they are connected properly.

• Make sure the interface cable meets the requirements of your interface board. See the documentation that came with the interface board.

• Make sure the interface board is installed correctly.

• When connected using the SCSI interface, make sure to turn on the scanner before turning on the computer.

• Make sure that EPSON TWAIN Pro is selected in your application.

EPSON Scan Server does not start.

• Turn off the scanner and computer, and check that they are connected properly.

• Make sure the interface cable meets the requirements of your interface board. See the documentation that came with the interface board.

• Make sure the interface board is installed correctly.

• When connected using the SCSI interface, make sure to turn on the scanner and then your computer.

• Make sure that a scanner supported by EPSON Scan Server and EPSON TWAIN Pro is connected to the scanner server PC.

• Make sure EPSON TWAIN Pro Network is installed on the scanner server PC (the PC which is connected to the EPSON scanner).

EPSON TWAIN Pro Network does not start.

• When connected using the SCSI interface, turn on the scanner first, then turn on the scanner server PC.

• Make sure that TCP/IP is selected as the networking protocol. If you are not sure how to select the networking protocol, consult your network administrator.

• Make sure that the cables which connect the EPSON scanner, the scanner server PC and the client PC meet system requirements and are properly connected.

• Make sure the interface card is installed correctly.

• Enter the correct IP address in the EPSON TWAIN Pro Network setup dialog box.

To use EPSON scanners in a network environment, you need to assign IP addresses to the scanner server PC and client PCs.

If EPSON scanners are installed in an internal LAN (Local Area Network), that is, isolated from the Internet, the following IP addresses can be assigned to the scanner server PC.

Note:

If you use IP addresses from these ranges, you will not be able to connect this LAN to the Internet in the future, otherwise there will be IP address conflicts.

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

If you plan to use a scanner server PC in a network connected to the Internet, you should acquire a formal IP address for the scanner server PC from the Internet organization of your country.

• Make sure one of the naming services such as DNS, WINS, or LMHOSTS is used in your network. Otherwise use an IP address to specify the EPSON TWAIN Pro setup dialog box.

The Auto Document Feeder or Transparency Unit cannot be selected.

Make sure the optional equipment is installed correctly. For installation instructions, see Using the Automatic Document Feeder or Using the Transparency Unit.

[Top]

You cannot scan from the Automatic Document Feeder.

• Make sure Auto Document Feeder is selected as the Document Source in EPSON TWAIN Pro.

• If the Automatic Document Feeder is open, close it and try again. If the Automatic Document Feeder is opened while scanning, remove any jammed paper, and reload any document which has not yet been scanned, then restart EPSON TWAIN Pro.

• Take the jammed paper out and reload the document, then restart EPSON TWAIN Pro.

Paper jams in the Automatic Document Feeder.

Follow these steps to remove the jammed paper.

Open the Automatic Document Feeder's cover.

Pull forward on the jam-release lever and slowly pull the jammed paper out of the feeder mechanism. (Be careful not to pull too hard; the paper may tear, making it more difficult to remove.)

Close the document feeder cover and make sure the READY light is on and not flashing, and the ERROR light is off.

The scanner does not scan in Windows 98 after changing the SCSI ID number or the SCSI board.

Depending on your Windows 98 version, you may have to uninstall the scanner from your system before changing the SCSI ID number or replacing the SCSI board. For instructions, see "When changing the ID number or replacing the SCSI board in Windows 98" on page 2-15 of the Setup Guide.
