I am using 32 bit Ubuntu 12.04 LTS and bought a Canon i-Sensys MF4750 printer + scanner + fax. There is a driver on the official Canon homepage only for the printer, and that works fine. But I need the scanner too...
The scanner is not recognized automatically (I connect it by USB). I installed SANE, but still doesn't work (I followed the steps here: https://help.ubuntu.com/community/SANE%20-%20Installing%20a%20scanner%20that%20isn%27t%20auto-detected
when I type sane-find-scanner than it finds it as follows: found USB scanner (vendor=0x04a9, product=0x2774) at libusb:002:005
But when I try to scan (SimpleScan, XSANE, Scanimage...) it just does not work (no scanner).
How can I get to work it? How can I get a driver for this scanner (probably SANE is not supporting my model)?
Please write in very simple way, I have very poor knowledge about Linux systems... :)
