Scanner Options, Maintenance and Troubleshooting
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.
Problem: I tried to 'Repair' the One Touch application by using the 'Change' function through the Add/
Remove Program within the Control Panel and was not able to repair it. How do I repair One Touch?
1. Before attempting to repair One Touch, unplug the USB cable connected to the scanner.
2. Perform the Change/Repair function again. If you are asked for the Install DVD, insert the disc into the DVD-
ROM player and click OK.
3. When prompted, plug the USB cable back into the scanner.
4. When the installation process finishes, click OK on the Complete The Installation window, and then click
Close.
5. Reboot your computer.
Problem: One Touch no longer functions after installing Internet Explorer 7 on Windows XP. How do I
resolve this issue?
