Canon Pixma MX700 Scanner Problem

I was having the same problem, and thanks to the person who posted solution number two which simply highlighted the fact that the apparently software that came with the Canon Pixma MX700 unit is not compatible with Window Vista.

The reason I was confused is because the printer was working perfectly fine across the network, but when I went to scan my computer would tell me that it can't communicate with the scanner. I'm thinking ... "well since you can communicate with the printer, you should be able to communicate with the scanner, after all, they're the same device!"

As a workaround, I used a third party program to do the scan (in this case, Photoshop) and everything worked fine. If you have Photoshop, just go to file > import to start the scan. If you don't have Photoshop, I would think whatever program you are using for image editing may have the same functionality.

Hope that helps,
Brian

I had mine hooked to an accessory USB2 Card. I moved the cable to one of the "main" usb ports on the motherboard and all is well again. Good luck!

First, go to the windows directory and look for the Twain32 subdirectory. Delete any competing scanners listed. You may have one from an old installation. Disconnect any other printers from the computer, unplugging the USB cord. Best if you unplug all devices except for the mouse and keyboard. Make sure in the device manager there are no yellow exclamations or red marked items (showing conflicts or unworking devices). If there are, uninstall the devices by right clicking them. Uninstall the canan printer/ scanner via the add programs in the control panel. Then reinstall the canon printer/ scanner. Unplug the canon scanner while installing the software until prompted to connect it. Then go to the canon Navigator, which will be in the utilities directory in the start "all programs." Rt click the Navigator and run it as an adminstrator. By now it should work. If it only works when you rt. click it and run as administrator, rt click and go to properties and check that you always want to run it as an administrator. Sometimes this last step is necessary even though the user is an administrator. Thank Vista for all security hassle. I got this by looking through their knowledge base and talking to technical support. It took a lot of work. Let me know if this works. [email protected]

I looked in the ReadMe file for the mx700. It said that Vista will not allow the canon software to scan, that you have to use Windows instead. I opened my windows photos program, and hit import from scanner off of the file menu. You have to tell it to import in color and from the flatbed (or feeder if you like) and it works fine now. Thanks very much, Windows, for making that executive decision for me!

Running vista and 2 PC's, neither work using network scan utility the scanner doesn't show up on the list.

Can you switch to a network install? My local windows clients worked fine, but now have 1 vista and 3 xp on the LAN - the "network scan utility" works for us - might be worth a shot. good luck to you both.
