4. If it is not present, insert the UMAX VistaScan CD-ROM into the CD-ROM drive and reinstall
VistaScan.
5. Unplug the scanner cable from the back of the computer, and then plug it back into the USB port.
6. Verify there is power to the scanner.
7. If the scanner does not show up, and there is no change in the Device Manager, try another USB port.
If the scanner still does not appear, contact your computer manufacturer.
Problem:
Your system resources are low. Your system resources are the amount of free resources your system can
call on at a given time. This should be at 90% or above to run a scanner. Anything under 60% will cause
system freezes or link fails when you attempt to access the scanner.
Solution:
Follow the steps below to determine if your system resources are too low to operate the scanner.
1. Click the My Computer icon using the right mouse button. A pop-up menu appears.
2. Click on Properties using the left mouse button.
3. Click the Performance tab (the fourth tab under System Properties).
4. Look in the System Resources area (the second section). This number should be above 90%.
5. If not, press and hold down the CTRL+ALT keys and tap the Delete key once. This brings up the
Close Programs window.
6. You need to end all tasks running except the EXPLORER and SYSTRAY items. To end a task,
highlight an item in the Close Programs window and click the End Task Button. Repeat this step for
each task you want to end. The programs will return upon restart. Repeating this process may be
necessary.
Macintosh Problems and Solutions
Problem:
When I daisy chain the scanner with other USB capable devices, I get a scanner error.
Solution:
Many Macintosh computers have at least two USB ports. We recommend that you connect your scanner
directly to one of these ports. Daisy-chaining the scanner, or running the scanner through a hub, can cause
the signal to be lost before it is communicated to your computer.
To make the troubleshooting process easier, disconnect your scanner from other USB capable devices or
hubs when troubleshooting.
Problem:
I cannot get the scanner to install properly, or it does not run once it is installed.
