[REQUEST] Addition of Pixma G2000

[droidzone]

I see that this repo has support for Canon G3000. Kindly add support for G2000 too. Any kind I can to find out configuration parameters for this, I am willing to help.

Hi,
Our project is based on the scanner supported by Canon. Unfortunately the G2000 is not. Let's try something:
sudo apt-get install devscripts debhelper libglib2.0-dev libgtk2.0-dev libusb-1.0-0-dev libtool-bin libjpeg-dev
mkdir ~/tmp
cd ~/tmp
wget https://github.com/Ordissimo/scangearmp2/archive/master.zip
unzip master.zip
Add line <<ATTR{idVendor}=="04a9", ATTR{idProduct}=="1795", MODE="666">>
after line <<ATTR{idVendor}=="04a9", ATTR{idProduct}=="1794", MODE="666">>
in scangearmp2-master/scangearmp2/etc/80-canon_mfp2.rules
cp -a scangearmp2-master scangearmp2-3.40
rm -rf scangearmp2-3.40/.git scangearmp2-3.40/debian/
tar cJvf scangearmp2_3.40.orig.tar.xz scangearmp2-3.40
cd scangearmp2-master
debuild -tc
sudo dpkg -i ../scangearmp2_3.40-1_amd64.deb
sudo echo "canon_pixma" >> /etc/sane.d/dll.conf # for activate the backend in sane
Restart OS

Thank you for your response. I've tried the step-by-step instructions you kindly provided. There was a key signing message while doing debuild which I suppressed with the -uc -us switches. Installed the .deb, added the line for canon_pixma and restarted. The scanning function is still not detected by scangearmp2 or sane's scanimage -L. Can I try anything else? If you need any logs or debug info, just tell me what to get. I've been also working with the sane email list, but unable to get the printer to scan.

With a sane-find-scanner, it shows:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

There's been perhaps a little progress on the sane list. I added the following lines suggested in the mailing list to /usr/lib/bjlib/canon_mfp2.conf

[G2000 series] 0x1795 0x0131 [G2000 series] 0x1795 0x0153 [G2000 series] 0x1795 0x0151 [G2000 series] 0x1795 0x0133 [G2000 series] 0x1795 0x0137

Then did: echo "#G2000 series" >> /usr/lib/bjlib/canon_mfp.conf echo "usb 0x4a9 0x1795" >> /usr/lib/bjlib/canon_mfp.conf

Now, On launching scangearmp2 (which is the version I compiled as per your instructions ), it now showed Canon G2000 series (libusb:001:008)., But after selecting that, and testing the scan, it shows dialog for save folder and then does nothing.
