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
®
RoadWarrior 4D is selected as the scanner.
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 software 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
: My computer keeps giving me out of memory error messages.
An “Out of memory” message may appear when scanning long pages at higher resolutions. This error is most
often seen on older versions of Mac OS X, due to the large file size created when scanning long pages in color or
grayscale at 300 dpi or higher. If you see an out of memory error message, please try adjusting the page length
and/or scan resolution.
Problem
: The paper jams in the scanner.
To reduce the number of paper jams, smooth and straighten the paper before scanning. If paper jams are
occurring more frequently, try cleaning the roller with a soft cloth dampened with Isopropyl rubbing alcohol.
Excessive dust on the roller can make it appear worn and will cause issues feeding paper. See
Cleaning the
Scanner
on page 22 for cleaning instructions.
If the documents you are scanning are thin, fragile, or severely wrinkled, try scanning using the scanner’s carrier
sheet. Please refer to the Loading Documents chapter of the scanner guide for instructions.
Problem
: Images are corrupted when scanning and saving as a GIF file format.
This is a known issue when using older versions of OS X, at this time the issue has been seen on 10.6 and 10.7 but
you may see this problem on other versions of OS X as well. Please use a different file format when scanning if you
are seeing corrupted image.
Problem
: If the USB cable is disconnected during a scan, the scanner does not reconnect when the USB cable is
plugged back in.
Unplug the USB cable from the scanner, and then plug it back in. If the scanner does not reconnect:
1.
Unplug the USB cable from the scanner.
2.
Restart your computer.
3.
After the restart is complete, plug the USB cable back in.
Status Light Troubleshooting

Steady blue
—indicates the scanner is receiving power. When the scanner driver is installed, it also means
the scanner is ready to scan.
■
Blinking blue
—indicates that the scanner is busy (e.g. when scanning or calibrating).
■
Blinking red
—indicates that there is a hardware error.
