Did you restart the computer and scanner? If the scanner gets a paper jam, or looses connection because
of an error, try restarting your computer and power cycling the scanner.
n
Did you plug the scanner into a USB hub? If you’re using a USB hub to connect the scanner try plugging
the scanner’s USB cable directly to the back of the computer. It is not recommended that you use the scanner
with a USB hub, if you are using a hub, the hub must have its own power supply.
n Is the USB cable 6’ or less? If you are using a USB cable that is longer than 6’ you may lose connection to the
scanner. The recommended USB cable length is 6’ or less, the USB cable provided with your scanner is within
this range.
n
Did you select another image source in the scanning software? If you use multiple imaging devices with
your computer, such as a camera, all-in-one printer, or another scanner, you may have selected another
source for images. Make sure Visioneer
®
Patriot
TM
P90 is selected as the scanner.
Problem: When the scanner is powered on, it makes noises and won’t stand ready.
There are two possibilities:
1. You might fail to push the scanner shipping lock to its “unlocked” position first. If this is the case, pull the
scanner status switch to its "unlocked" position first.
2. The scanner is not placed on an even, flat desktop surface. This may cause the scanner to malfunction.
Problem : Why does my scanner not function after performing a system restore on Windows?
The system restore process may have corrupted some of the driver components. It is recommended that you
reinstall your scanner driver. Please refer to
Uninstalling Your Scanner on page 53 for installation instructions.
Problem : Why won’t my scanner buttons work after scanning with Windows Image Acquisition (WIA)?
After performing a scan using the WIA interface you must close the application you were using before scanning
with the buttons on the scanner. This does not occur when scanning using the TWAIN or ISIS interface.
Problem : Why won’t my scanner work after the computer has been sitting idle for several hours?
To resolve the problem, simply turn off the scanner power then turn it back on again.
This may occur after Windows goes into power saving mode to “hibernate” the computer into a low power state.
When you move your mouse or type on the keyboard it “wakes” the computer back up and restores full power to
the system. This power fluctuation during the computer’s hibernating period may sometimes cause the scanner
to lose communication to the computer.
Problem : The installation will not complete successfully. If installation finishes, the scanner’s OneTouch options
do not seem to work properly.
A likely cause is that some driver programs are already installed on your computer for another scanner. They may
be interfering with the installation and OneTouch options, and you need to remove those other drivers and re-
install your Visioneer
®
scanner. You can remove these programs from the Windows Control Panel. Please refer to
the user manual provided with your other scanner hardware for instructions about removing the driver and
software for that unit.
