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 OneTouch 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 OneTouch?
1. Before attempting to repair OneTouch, 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: I am getting an error message that OCR fails every time I try to scan using the OCR features from
OneTouch. What is the problem?
Anti-SpyWare software that is set to always run may interfere with the driver functionality. It is recommended
that you temporarily disable or suspend the automatic protection feature during scanning. After scanning is
complete and your file has been saved, turn the auto-protect feature back on. You do not need to close the Anti-
SpyWare software.
Uninstalling Your Scanner
Use the options in the Windows Control Panel to remove the scanner driver and modules, and any other software
provided with the scanner.
