This is a message informing you that the software does not install an ISIS driver. This is the correct
behavior of the Kofax VRS software, the ISIS driver for your scanner was installed when you chose an
ISIS installation option when installing the scanner driver.
Problem: Why does my scanner not function after performing a system restore on Windows XP or
Windows Vista?
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 193 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 USB cable was unplugged while scanning, now the scanner won’t work. What should
I do?
Simply turn off the scanner power then turn it back on again. This will reset the scanner and make it
available for scanning.
Problem: When using "Create single image files" not all of the pages scanned are sent to the
destination I chose. Where are they?
There are a limited number of times that an application can open. When "Create single image files" is
selected and you are scanning to a destination application, each side of the page scanned will open a
new instance of that application. If you want to have an image open in an application immediately,
limit your scan batch to less than 5 pages.
Alternatively, you can set your destination to be a folder location on your computer or network using
"Transfer to Storage". Select any file format and then scan a large batch of papers. At the end of
scanning, the driver will immediately save all pages scanned to that folder location without opening an
application.
Problem: I have selected "Skip Blank Originals" but not all of the blank pages have been removed.
Why are there still blank pages in the file?
If you are scanning light weight paper, such as 16lb or 18lb printer paper, the scanner may be picking
up faint images through the paper and the driver will not drop those pages out of the final file. The
"Skip Blank Originals" result will vary based on the DPI range and paper weight. Generally 100 dpi or
150 dpi produces the best results.
