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: Troubleshooting sane - Adding a Scanner that is not auto-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...


1. Printer driver:

Canon i-SENSYS MF4750 - Support - Download drivers, software and manuals

2. Scaner driver :

sudo apt-get install libusb-dev build-essential libsane-dev

sudo apt-get install git-core

Download latest sane source code

git clone git://git.debian.org/sane/sane-backends.git

cd sane-backends



sudo make install

3. Set Permissions for USB (allows you to scan without using sudo)

sudo gedit /lib/udev/rules.d/50-udev-default.rules


SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ... , MODE="0664" 


SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ... , MODE="0666" 


sane-find-scanner -f

scanimage -L

Enjoy !!!

    This answer looks to take a guess on what the problem actually is without second checking if the solution resides in the latest code. It is worth a try but maybe you should mention why you think this will solve the problem. – Requist Dec 15 '14 at 17:54
