Scanner causes freeze

[jfh]

I am the ultimate Linux newbie.  I managed to install Linux Lite on my old Toshiba Satellite
A105 and connected my old scanner to it (CanoScan N670U), but found that using Simple Scan caused the computer to freeze.  It had only a total of 1GB memory installed, so I upgraded it to the maximum - 2GB, and installed SANE, but it would scan only part of a page of text when set for "Color".  When I set SANE for "Text" it started scanning, then the computer froze, just as with Simple Scan. The version of Linux Lite on the computer is 3.2 (I run the upgrade utility whenever I use this computer.)
Is the problem that there is still not enough memory for scanning to function on this old laptop, or is there something I'm doing wrong? Thanks for any help.

Hi [member=6480]jfh[/member]

It might be a driver problem. I checked on Canon website and there's no driver available for that model. Did you install "libsane-extras" when installed SANE? If you didnd't open a terminal and type

Code:

$ sudo apt-get install libsane-extras

Once installed type in your terminal

Code:

$ sudo nano /etc/sane.d/dll.conf

and scroll down the list of drivers names to yours, then comment it out; delete the "#" character in front of the driver's name compatible with your device, hit ctrl+o to save the changes and ctrl+x to close nano. Try again and see if that works.

Hope this helps!

Thanks, I will try that, even though I do not handle Terminal very well.  I did find, in the website below, that my scanner (CanoScan N670U) is listed as a supported device, whatever that means. I do not know how to interpret the entries in the lists on this site.
