canning functionality from the LJ3380 and CLJ2840 series All-in-One devices may not function until the correct Twain Data Source is selected by the user. This can be done by attempting to scan from the foundation scan executable "hppscan2.exe ".

• For the LJ3380 series this is located in C:\Program Files\Hewlett-Packard\LJ3015_LJ3020_LJ3030_LJ3380->hppscan2.exe
• For the CLJ2840 this is found in C:\Program Files\HP\Digital Imaging\bin->hppscan2.exe

When the "hppscan2.exe " is launched from this location where it resides, a dialog box will open with a "Select Source " box listing the installed Twain scanning devices available. If this box is not seen, then there is only one Twain device installed. In some instances user input is needed to chose the "correct" Twain data source for scanning to be successful from the LJ3380 and CLJ2840 series devices. If the incorrect Twain data source is selected- an error "Cannot initialize device " will be seen.

Try scanning from your PC, if you have a program that will allow it... if you have Word '97, you can do it like this:

1. With your scanner ready and the image on the scanner glass, in Clip Organizer, on the File menu, point to Add Clips to Organizer, and then click From Scanner or Camera.
2. In the Insert Picture from Scanner or Camera dialog box, under Device, select the scanner.
3. Click Insert. The new clip appears in the My Collections folder, in a folder named after your scanner
   

If you do not have Word '97, but a program that SHOULD work but doesn't have the correct driver, go to www.twain.org for the latest twain-compliant drivers for your scanner! You may also be able to find a simple scanning app (in the downloads section) at www.cnet.com

Hope this helps!

If you still experience problem scanning, un-install the entire software and re-install them all over. Install all the packages in the CD. Cheers!

First you need to follow the instructions for installing the scanner. It is important whether you connect the scanner before the software is installed and whether you work from the new hardware found box or just install the driver as software. It sometimes varies between operating systems as well.

Sometimes the twain files can become corrupted. Since other devices like digital cameras use the twain files they aren’t erased with a driver uninstall or overwritten with an install. If the twain files are gone the driver install will also install them.

Uninstall ScanGear (I think that is the Canon driver software) and remove the scanner if it is still showing in device manager and control panel under scanners. Unplug the USB.
Do a search for twain and delete all you find in the Windows folder. There is probably a folder and several files – delete them all. Do not remove any twain files not in the Windows folder.
Dig out the instructions and reinstall the scanner exactly according to them.

The problem was with the scanner,it was not twain compliant

So the 2 ways left with me was :

1.Download twain drivers for my scanner and install it.

2.Use wia32.dll

I chose second option as i didnt found any twain driver for my scanner.

Hope this can help any one.
