Software Troubleshooting
This section describes troubleshooting problems and solutions for
operating the supplied software (CaptureOnTouch).
If scanning is too slow
1
Close other running programs, if any.
2
Scanning can be slowed down by memory shortage caused by
memory-resident applications such as anti-virus programs. Close
such memory-resident programs if necessary to free up memory
space.
3
When insufficient hard disk space is available, the scanner may be
unable to create the necessary temporary files for scanned data.
Delete unneeded data on the hard disk to free up more space.
4
Scanning is slow if the computer's USB port is not Hi-Speed USB 2.0
compliant.
5
If using a common USB cable that is not Hi-Speed USB 2.0 compliant,
replace the cable with the supplied compliant cable.
6
When the scanner is connected to the computer via a USB hub that is
not Hi-Speed USB 2.0 compliant, remove the hub and connect the
scanner directly to the computer.
If scanned image files cannot be opened in an application
1
Scanned images saved as multi-page TIFF files can be opened only
by programs that support this file format.
2
Images saved as compressed TIFF files (single- as well as multi-
page) can only be opened by programs that support the compressed
format. This can occur with programs that are not compatible with
CaptureOnTouch. In this case, select " None" as the image file
compression format before scanning.
There is a display glitch on the UI screen of CaptureOnTouch
Depending on the computer that you are using, a display glich may occur
on the UI screen when there are too many Scan mode panels, Select
output panels, or Scanning Shortcut panels. Delete any panel that you will
not use.
