Twain Driver Problem
This is kind of a repost of a previous question, about a problem with
my Canon 8000F and connectivity. But this time there was an additional error message running on piece of softwa "Unable to Open Twain Source. Please Check Connection." I've inserted the message, in sequence, in the discussion below -- maybe the extra clue will help someone to help me. I have the Canon 8000F scanner, which has been working fine for several months with Windows 2000. Recently, after installing DSL, I needed to rebuild the entire system (reinstall operating system, all applications -- I did a clean build, but had to uninstall parts of Service Pack 4, which may have hashed things) -- and now am having problems. When I try to access the scanner from any app, including the Canon Toolbox, I get: "Cannot communicate with scanner. Cable may be disconnected. Check status. Scanner driver will be closed." Then, next dialog box: "Unable to Open Twain Source. Please Check Connection." I have tried installed a different Twain driver, CFM, and that also gives an error message. I went to the Microsoft download site and searched for a Twain driver, and came up dry. I notice that when Windows boots up, the scanner is not making the noise it previously made, some kind of reboot, testing-the-scanner sound. However, when the scanner is disconnected from the computer, and reconnected to the USB port, Windows definitely announces "New device found", and installs the scanner. The scanner is listed on the Control Panel; under System/Device Manager, it says the device is working properly. But under Scanners And Cameras the Status is listed as "Unavailable". The scanner remains connected to the same USB 2.0 port I used before (though I also tried the other USB ports, and that didn't help). The USB ports are working okay, because I test them with other devices, so it's clearly a software problem. I have uninstalled the drivers, and reinstalled with the latest from the Canon Web site. I have powered the scanner off, and on again. I also tested the scanner with my laptop, and the connection works fine there, so that scanner did not mysteriously break, it's working okay. I searched Usenet for previous posts on this problem, and found several people who have experienced the same thing. Only, none of the threads ended with a solution, other than: Reinstall everything from scratch. (A solution I'd obviously rather avoid.) Finally, in desperation, I tried reinstalling Windows 2K SP 4 (in spite of other problems that causes), and it didn't help. Any suggestions -- other than, "Rebuild the entire system AGAIN..." would be appreciated. Steve O. Standard Antiflame Disclaimer: Please don't flame me.

I have a Canon 5000F with the same problem as below, except I use XPHome
SP1. I visited Canon Australia Support who talked about reinstalling the TWAIN driver etc - see http://www.canon.com.au/support/cust...=canoscan5000f and it fixed the problem so far! You might want to visit Canon Europe Support - not that it helped me much at https://self-service.canon-europe.com/uk/pages/ Hope that helps. Steve "Steven O."

Actually, after much digging on the Web, I found a thread with the
source of my problem. I'm posting the solution, in case anyone, having similar problems, comes across this thread! Recently, in trying to address the fact that Win2K was running slowly, I disabled a bunch of startup programs -- and screwed myself up in the process. There is a program called stimon.exe, which stands for Still Image Monitor, that needs to run at startup. (You can select or deselect the process using MSCONG.exe.) Anyway, I had this deactivated, which is why the scanner would not respond. It needs to run at startup for your scanner to work. Would have been nice if there had been ONE !$*&^#$!% WORD ABOUT THIS on Canon's help site, or in their help file that comes with the product. Way to go, Canon tech writing staff. Steve O.

I've just loaded driver version 8.0.2.1 after uninstalling 8.0.1.0 with the
uninstall utility at http://ww2.canon-europe.com/cgi-bin/...&interfaceid=2 I disabled my antivirus checker when I installed 8.0.2.1. All now seems well afer restarting. You can't just install 8.0.2.1 over 8.0.1.0 - you have to unstall the driver first. I'll post any problems here if they occur with 8.0.2.1 Steve "Steven O."
