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 compliant with
high-speed standards such as Hi-Speed USB2.0 and USB3.1
Gen1.
(5) If using a common USB cable that is not USB3.1 Gen1 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 USB3.1 Gen1 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 happens when using applications that
do not support CaptureOnTouch's TIFF file compression. 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 glitch 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.
