TROUBLESHOOTING
Problem:
The device won’t work. What’s wrong?
Check for one of these possible causes:
■
Are the cables loose or not plugged in securely?
Inspect the cable connections. Make sure the
cables are plugged in securely.
■
Is the device’s status light on?
Turn on the device’s power. If the status light doesn’t come on, plug
the power supply into another electrical outlet. If you are using a UPS battery back-up or power strip,
try plugging the device directly to a wall outlet.
■
Did you restart the computer and device?
If the device gets a paper jam, or looses connection
because of an error, try restarting your computer and power cycling the device.
■
Did you plug the device into a USB hub?
If you’re using a USB hub to connect the device try
plugging the device’s USB cable directly to the back of the computer. It is not recommended that you
use the device with a USB hub, if you are using a hub, the hub must have its own power supply.
■
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 device. The recommended USB cable length is 6’ or less, the USB cable provided
with your device is within this range.
■
Did you select another source?
If you use multiple imaging devices with your computer, such as a
camera, all-in-one printer, or another device, you may have selected another source for images. Make
sure Visioneer

Problem:
Why does my device 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 device driver. Please refer to
Uninstalling Your device
on page 96 for installation
instructions.
Problem:
Why won’t my device work after the computer has been sitting idle for several hours?
To resolve the problem, simply turn off the device 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 device to lose communication to the computer.
Problem: My computer keeps giving me out of hard drive space error messages.
The minimum requirement of free hard drive space is for the installation of the device driver and basic,
low resolution, scanning. High resolution scans result in files that can be over 1 gigabyte in size. Free up
some space on your hard drive for the software to be able to save the scanned images.
Problem: The paper jams the ADF.
To reduce the number of paper jams, smooth and straighten the paper before printing, and adjust the
guides to the paper size. If paper jams are occurring more frequently, try cleaning the
device’s
components, see
Cleaning the device
