Remove all other devices from the USB chain, so the scanner is the only device on the USB chain. Make

sure that the scanner power adapter is plugged directly into the wall, not into a power strip.

Problem:

The following error message appeared: "Error: No Driver Found".

Solution:

The Macintosh OS generates this message if it could not find a driver in the System Folder for the USB

device you just connected. You may have forgotten to install the software that came with the device, or

you may have put the device driver (i.e., the software that allows Macintosh to recognize and communicate

with the USB device) in the wrong place in your System Folder.

Re-install the software driver from the VistaScan CD-ROM. Make sure the extension is loaded and on.

Problem:

The following error message appeared: "Scanner not found" or "Unable to control scanner".

Solution:

Follow this procedure:

1. Confirm the scanner is plugged into the computer's USB port.

2. Go to the Apple Systems Profiler, listed under the Apple menu.

3. Go to the Devices & Volumes tab (Control + 2). Verify the scanner is listed under the USB tree as:

Class: 0

Product ID: 16

Vendor ID: 5638

4. If not, disconnect the USB cable from the computer.

5. Go to Command, Update All Information (Command + U).

6. Reconnect the scanner, and Update All Information again. Is the scanner listed? If no, please call

UMAX Technical Support.

Try the following solutions, if you are still experiencing scanning problems:

1. Plug the scanner power adapter directly into the wall outlet and not in a surge protector.

2. If using a USB hub, plug the scanner directly into the Macintosh USB port.

3. If you are using an iMac, do not run the scanner off the keyboard.

4. Download all updates for your Macintosh for USB from the Apple's Web site http://www.apple.com.
