Issues with the TWAIN Driver:

The TWAIN standard is regularly updated, and software development 
companies incorporate these changes in their new applications. 
However, problems may occur if the application does not fully 
support the TWAIN standard.
In order to ensure that users can use our software without any 
problems, Canon works closely with a number of software 
development companies to solve these problems.

1. Problems that may occur when using some chips for display cards 

If you start TWAIN driver from TWAIN driver-compatible applications 
(such as ArcSoft PhotoStudio), operation of TWAIN driver may unstable 
using some IC chips for display. 
If this happens, use the [dispinit.exe] fix program.  It is in 
[TROUBLESHOOT/DISPINIT] folder on the SOLUTION DISK.
You have to run the [dispinit.exe] fix program every time you start a 
computer. If you register [dispinit.exe] short cut as a Windows startup 
program, you can run the program automatically every time the computer 
starts up.


2. RAW images and movie files

You cannot view thumbnail images of RAW images and movie images 
using this driver.
You should therefore always check the contents of a memory card 
before formatting it.


3. Compatibility issues

After testing many TWAIN-compatible applications and operating 
environments, we have identified the following compatibility 
problem.

The maximum amount of images that can be transferred to 
Photoshop 5.0 LE in one go is 30.


4. Communication between Canon Camera PTP TWAIN Driver and the 
camera

(1) When opened, the driver will periodically communicate with a 
camera that is connected to the computer. During communication 
with the camera, do not operate any of the camera's switches, 
remove the camera's memory card or battery, or unplug the 
communication cable.
    Depending on your computer's operating environment, doing any 
of the above could result in faulty operation of your computer.
    You should therefore close the driver before doing any of the 
above.

(2) Do not put your computer into standby mode or hibernation 
mode while the camera is connected to the computer's USB port.
    If you have accidentally put your computer into standby or 
hibernation mode while the camera is still connected to the 
computer's USB port, resume from standby or hibernation mode with 
the cable still plugged in.
    If you pull out the cable while still in standby or 
hibernation mode, you may not be able to resume correctly from 
standby or hibernation mode, depending on the computer model. 
Please refer to your computer's manual for more details about 
standby mode and hibernation mode.


5. Issue with Installation

When installing this driver, the install may not complete 
successfully if you select a root drive, such as the c:\ drive, 
or an existing folder as the installation destination folder.
In this case, uninstall and install again selecting create a new 
folder.
