SPI Driver Open Failure

Description:

You get an error message saying SPI Driver Open Failure when you click on Acquire, particularly on IBM Aptiva Computers.

Cause:

Hand scanners have a device driver which loads into memory during bootup. If this driver didn't load properly, you will get the error message.

Solution:

The scanner's device driver is picky about what order it loads in during bootup. Move the device driver to the top of your Config.sys file and that should fix the problem. Referring to the diagram below, here are the steps to do this:

1. Start the System Configuration Editor.
           In Windows 95, click START then select RUN. Type in Sysedit and click OK.
           In Windows 3.x, open the Program Manager's File Menu and click RUN. Type in Sysedit and
           click OK.

2. Move the Config.sys file to the front. The blue title bar at top will have the name of each file on it.
    The Config.sys file will be the second window back.

3. Locate the Twain device driver line and highlight it as in the above diagram. It is usually at the bottom
    of the file. The device line may not match the above line exactly because it is different for various
    various scanners.

4. Cut the device driver line to the Windows Clipboard by holding down the Ctrl key and pressing the
    X key.

5. Move the cursor to the top line of the file and press the HOME key on your keyboard.

6. Press enter one time then press the up arrow key to move the cursor to the blank line you just
    created at the top of the Config.sys file. Hold down the Ctrl key and press the V key to paste the
    device driver line back in.

7. Save the Config.sys file and reboot your computer. You should be able to scan now without getting
    the error message.

If these steps don't solve the problem, you may have a bad interface card. Call our Technical Support Department for further assistance.
