CanoScan error: Make sure that there is enough space on the target disk

I have used my scanner, CanoScan LiDE 70, to scan documents without any problem since 2006. Today when I used it, I got the following error message :

Unable to scan: Make sure that there is enough space on the target disk.

This error message was not helpful because my target disk still had so much space. When I changed the default setting to another disk, it still showed the error. When I rebooted my PC, I still got this error too.

When I was surfing some forums, I could not get the correct answer. The best way for me in my mind was to uninstall CanoScan LiDE 70 driver and install it again to see what’s going on.

After the uninstall and install CanoScan LiDE 70 driver, there is no error message. It is working for me.

If you get this error message next time, just uninstall it and install it again. It might work for you.

Thank you for your inquiry. We value you as a Canon customer and
appreciate the opportunity to assist you. We sincerely apologize for
any difficulties you have experienced with the 4400F and Target Disk

For an unknown reason, the computer is not allowing temporary data to be

To fix this, please perform the following:

1. From the CanoScan Toolbox, click the Settings button.

Where Temporary Files are Saved:". Click the Browse button.

3. Browse to a folder, such as C:\Temp, and then click OK.

4. Click OK again to exit the Settings window.

Try scanning again. If you receive the same error, then there could be
an issue with the permissions of your user account. Creating a new user
account could resolve the issue. Please perform the following to try

1. Click Start and then Control Panel.

2. Click User Accounts and Family Safety.

3. Under User Accounts, click Add or remove user accounts.
