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.
