Problem:
Your system goes to the Finder when you try to acquire the
scanner.
Solution:
Plug the scanner into its own power outlet. If still does the same
thing, please call UMAX Technical Support.
Problem:
The following error message appeared: "Error: Not Enough
Power to Function"
Solution:
The Macintosh OS generates this message if:
A device draws too much power from the USB bus
One or more devices plugged into a hub require more power
than is available
You attached a self-powered device (such as a printer or floppy
drive) to your computer without plugging it into an electrical
outlet.
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.
