Software Troubleshooting
This section describes troubleshooting problems and solutions for
operating the supplied software (CaptureOnTouch and
CapturePerfect).
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 or CapturePerfect. In this case,
select “None” as the image file compression format before
scanning.
If CapturePerfect cannot open some PDF
files
Some PDF files created by non-Canon programs cannot be opened
by CapturePerfect.
Q & A (Useful tips)
Here are some useful tips for scanning documents.
Where are scanned images saved? Can the save
destination be changed?
Images are saved to the following locations, according to program
settings. All destination locations can be changed to other folders.
CaptureOnTouch
➜ For Scan First scanning, files are saved in the folder specified on
the Output method screen.
➜ For selected job scanning, files are saved in the folder specified on
the [Output settings] tab during job registration.
CapturePerfect
➜ During normal scanning operations such as single-page scanning,
the image file save destination can be specified each time scanning
is performed.
➜ When scanning using a registered job, files are saved to the folder
specified by the job settings.
How are scan settings performed?
CaptureOnTouch
➜ For Scan First scanning, click [Scanner setting] on the first (main)
screen to display available scan settings.
➜ For selected job scanning, settings are available on the [Scanner
setting] tab when registering the job.
CapturePerfect
➜ For normal scanning, click [Scanner Setting] from the [Scan] menu
to open the scanner driver setting screen, and make settings there.
➜ Scan job settings are made for each job.
How do I save multiple pages in one file, or save one file
per page?
When scanned images are saved in BMP or JPEG format, each image
is always saved in a separate file.
When scanned images are saved in PDF or TIFF format, you can
specify multi- or single-page files. See also item 8 in
“Common
Problems and Solutions” .
