Scanner Canoscan 4400F

target disc means hard drive or other disc that the file temporary loads to. its either full or most like write protected. right click on the scanner in control panel or the scanners. select "where" to save to in the popup menus

check for disk partition permission, be sure you have full permission access.

When you scan a picture, you send it to a "Target" folder which you can set up in your scan options or settings.

At a guess your current destination or target folder is getting to large for the hard drive that its registered on

You've 2 options, clean out the target drive or use the scan options to send your pictures to a new destination with plenty of space.

You need a scanner application such as Adobe Photoshop or other program.

Cannon has one for your scanner at this link.

Easy fix... Happens all the time with all Canon scanners. Open the tool box...click on settings and change the folder where the temporary files are stored to another folder of your choice...or create a new one in your documents. That's it!

I have just cured this"not enough space on the target disc" on my set up.I had the problem from day one after buying scanner but learned to get around it.Today I went into Toolbox and opened settings and made a note of the target address. Then checked properties of the target folder and found there was 86mb in a space for 80mb.This was the default setting chosen by the installation programme. I went to my documents and made a new folder and called it Canoscan, clicked ok and it became the new target and the fault is gone. Hope it works for others.

This is most likely only happening when attempting to scan through the CanoScan Toolbox. You can scan directly through ArcSoft PhotoStudio which came with the scanner. However, the error through Toolbox is likely caused by some limitation or restriction in the computer, possibly permissions of some sort. You may try deleting temp files from the Temp folder on the hard drive.

Try deleting temporary files and reinstall the Toolbox.

Try deleting temporary files.

I had exactly as described on my new 4400f scanner. Have resolved by uninstalling the toolbox software (it was at 5.0.1.2), downloading toolbox s/w from canon site, file name is S6A04mux.exe - toolbox 5.0.1.1 Installed this and all works from the scanner front panel
