--------------------------------------------------------------- Canon PowerShot TWAIN Driver Readme file for PowerShot 600 Version: 1.21 November, 1996 --------------------------------------------------------------- (c) Copyright 1996, Canon Information Systems ________________________________________________________________ Thank you for your purchase of the Canon PowerShot 600 digital camera. This readme file contains new feature/difference in version 1.21 as well as some information which may be helpful in diagnosing problems with the PowerShot Twain driver or the PowerShot 600 digital camera. This file can be viewed or printed again in the future from its location in the PowerShot directory (indicated in the title bar of the setup screen for viewing this file). 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. _________________________________________________________________ -------- CONTENTS -------- 1.

(a) Disabling "Show window contents while dragging" option 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. <End of File>Download Driver Pack
