diagnosing problems with the PowerShot Twain driver or the
PowerShot 600 digital camera. This file can be viewed or printed

A NOTE ABOUT TWAIN:
Since the TWAIN standard is being updated on a regular basis, and
software application companies try to address these changes, you
may occasionally experience some minor problems caused by
applications that are not fully TWAIN compliant. Canon works
closely with software manufacturers on compatibility issues to
ensure user's a trouble-free experience.

1. New Feature/difference in Version 1.21
==========================================
To ensure customer satisfaction, the following changes has been
made in version 1.21 driver:
-Thumbnail Gallery will not display the newest image first.
-Time Zone selection box has been simplified.
-More detailed information about the image/picture is available w/
a right mouse click.
-Parallel port and Camera source option are modified for a more
friendly use.
2. General Notes:
==================
(a) The camera not ready state
The camera is not accessible when the dashed line symbol,
"----", is displayed on the camera LCD panel. This symbol
indicates the camera is not yet ready for communication.
The list of actions which cause the camera to be in this
state include, but are not limited to, the following:
1. When the camera is first locked in the cradle.
2. When you download thumbnails from camera using
PowerShot software and then exit PowerShot.
3. When you bring up PowerShot Profile without having
downloaded thumbnails from the camera and then exit
PowerShot Profile.
If you do access the camera while this symbol is displayed on
the LCD panel, by pressing the camera button from PowerShot's
Image Source control or pressing the camera button from
PowerShot to access PowerShot Profile, you will see the
following error message:
"Device error: The camera was not found. Connection may be
bad or the camera may not be ready. Please check cable,
power, cradle lock or battery."
In this case, just wait until the symbol disappears from the
LCD panel and try again.
(b) Erase All from PowerShot 600 Version 1.21 TWAIN driver
when the camera battery level is not full
If you wish to delete all pictures & sounds from both the
camera's internal storage as well as any PCMCIA/ATA card
inserted in the camera, you may use the Erase All button
located on the main PowerShot 600 Version 1.21 TWAIN driver
window. To avoid unexpected results, make sure you have
adequate battery power to completely finish the Erase All
operation. If you have a large number of pictures & sounds
to erase, the deletion process may take a few minutes. In
this case, make sure that the battery pack (Ni-Cd
rechargeable) or battery holder (AA-size alkaline batteries)
in the camera has fully charged (Ni-Cd) or new (alkaline)
batteries. Alternatively, connect the Camera Connector of
the Battery Charger to the Battery Charger Terminal of the
Camera Station CS-36 before attempting an Erase All operation
from the PowerShot 600 Version 1.21 TWAIN driver user
interface.
(c) Image loading time concern
When you experience a long loading time for the Thumbnail
Gallery, you may want to check your temporary directory
for .tif files generated by PowerShot and not being cleaned
up due to an abnormal exit from PowerShot. You just
need to delete these .tif files to resolve the problem.
3. Adobe PhotoShop v. 3.05 and PhotoShop LE v. 3.05
====================================================
(a) Cannot find Twain drivers under Windows 95
Under Windows 95, Adobe's PhotoShop v. 3.05 has difficulty
finding and loading Twain drivers which are composed of
multiple DLL's when they are located in their own directory
below the TWAIN directory. A simple workaround is available
within Windows 95 by performing the following steps only if
Adobe's applications are installed after PowerShot Twain driver:
1. Run the REGEDIT.EXE program (found in the Windows
directory).
2. For PhotoShop Locate the key:
HKEY_LOCAL_MACHINE\Software\Microsoft
\Windows\CurrentVersion\App Paths\photoshp.exe
For PhotoShop LE, the final part of the key is
photosle.exe.
3. Double click on the Path value to change the search path.
4. Add the location of the Twain driver subdirectory to the
existing path, using a semi-colon as a delimiter. For
example:
C:\Program Files\PhotoShp;C:\Windows\Twain\PwrShot
5. The PowerShot driver should now be found successfully.
(b) Selecting the correct 16-bit TWAIN Data Source
Adobe Photoshop v. 3.05 and Photoshop LE v. 3.05 support both
the 16-bit TWAIN and new 32-bit TWAIN_32 standards. When
selecting a TWAIN or TWAIN_32 source, care must be taken to
use the correct one. PowerShot 600 Version 1.21 TWAIN driver
is a 16-bit TWAIN Data Source. Both 16-bit and 32-bit TWAIN
drivers may appear in the Acquire>Select Source dialog boxes.
To avoid unexpected results make sure that you use the
"TWAIN" Data Source option when either selecting a Data
Source (Acquire>Select TWAIN Source...) or Acquiring an
image(s) (Acquire>TWAIN...) with the PowerShot 600 Version
1.21 TWAIN driver. Do NOT use (Acquire>Select TWAIN_32
Source...) or (Acquire>TWAIN_32...).
(c) Using the Profile dialog of the PowerShot 600 Version 1.21
TWAIN driver with certain notebook computers.
Under Windows 95 with some notebook computers that use color
LCD display panels, the maximum character length allowed in
some date & time input fields may not be adequate to permit
entry of some date & time values. If this situation is
encountered with either Adobe PhotoShop v. 3.05 or Photoshop
LE v. 3.05, please use an alternate TWAIN-compliant graphics
application to set date, time, time zone, and owner's name
from the Profile dialog of the PowerShot 600 Version 1.21
TWAIN driver.
4. Micrografx Picture Publisher
================================
(a) Micrografx Picture Publisher w/256 color video drivers
When the Windows video driver is set to 256 color mode,
Picture Publisher often does not update its colors until
PowerShot is exited. This problem has been acknowledged by
Micrografx.
(b) Micrografx Picture Publisher 5.0 keyboard interactions
When Picture Publisher has an image open, many keyboard
interactions are not allowed to occur in the PowerShot
Gallery. This problem has been acknowledged by Micrografx
and is fixed in version 6.0.
5. Installing and Un-Installing PowerShot 600 TWAIN Driver
===========================================================
Once you have started the Installation program, remove an
installation diskette from your diskette drive only under the
following circumstances:
1. The PowerShot Installation program prompts you to do so.
2. You have completed the installation successfully.
3. You have Canceled out of the Installation program
(pressed "Cancel" button) before successful completion.
To uninstall PowerShot 600 TWAIN driver please carry out the
following procedure:
(for Windows 95 Users)
1. Click the Start button, point to Settings, and then click
Control Panel.
2. Double-click the Add/Remove Programs icon.
3. On the Install/Uninstall tab, click PowerShot, and then click
Remove.
(for Windows 3.1x Users)
1. Click the File option from Program Manager, and then click
Run.
2. Type '\Windows\Twain\Pwrshot\Psunist.exe
3. Click 'OK' to start.
6. Using PowerShot 600 Camera with the Canon MultiPASS MP-800,
MP-1000, C2500 MultiFunction Devices.
===============================================================
If you plan on connecting a PowerShot 600 Camera and a Canon
MultiPASS MultiFunction device to the same computer, please
make sure to do the following:
1. If you have more than one LPT port on your computer,
connect the MultiPASS device and the PowerShot 600 Camera
to separate LPT ports.
2. If you have only a single LPT port on your computer,
please refer to the user documentation which came with
your MultiPASS device to properly configure the MultiPASS
software so it can share usage of the same LPT port with
another device (in this case, the PowerShot 600 Camera).
The MultiPASS software has an "Exclusive Port Use" option
(enabled by default), which will prevent you from sharing
the same LPT port with another parallel port device.
7. Using PowerShot 600 Camera with the Canon BJC-610 Printer
=============================================================
If you plan on connecting a PowerShot 600 Camera and a Canon
BJC-610 printer to the same computer, on separate LPT ports,
avoid printing to the BJC-610 while Acquiring images from the
PowerShot 600. On slower computers, there may not be
adequate CPU time to successfully transfer image data from
the camera while simultaneously sending print data to the
BJC-610. In this event, you will receive a message from the
PowerShot 600 TWAIN driver which says, "Communication error:
Camera may not be connected." Wait for your print job to
complete, before attempting to reestablish communication with
the PowerShot 600 digital camera.
8. Using PowerShot 600 Version 1.21 TWAIN driver with Compaq
QVision EISA Video Adapter.
============================================================
If you plan to use the PowerShot 600 Camera Version 1.21 TWAIN
driver on a computer which uses a Compaq QVision EISA video
adapter, you may see some vertical black lines appear next to
some of the button controls used to operate the TWAIN user
interface. These lines do not affect the operation of the
TWAIN driver in any way. These lines only appear if you are
operating your Compaq QVision EISA video adapter in 640 X 480
resolution mode. These lines will not appear in other Compaq
video resolution modes (i.e. 800 X 600, 1024 X 768).
9. Microsoft Plus!
===================
(a) Disabling "Show window contents while dragging" option
If you are using the Microsoft Plus! add-on package for
Windows 95, you may experience some unusual movement of
the main window of the PowerShot 600 Camera Version 1.21
TWAIN driver while dragging it by the title bar using
your mouse pointer. In some cases, the main window may
not be accessible when moved to the extreme corner of your
video monitor screen. To avoid these problems, please
disable the Microsoft Plus! "Show window contents while
dragging" feature by unchecking the appropriate checkbox
located in the "Visual settings" options group.
