[sane-devel] Canon DR-3010C scanner

Mon Nov 26 14:59:07 UTC 2012

Hi Allan,

Yes, we are able to scan now through the main scanner (DR-3010C). What's left to be done is to be able to scan using an add-on device (canon flatbed scanner unit 101) that we have. It works like this - the main scanner is connected to the flatbed unit via USB cable, and the flatbed unit is connected to the PC via another USB cable (apparently the flatbed has a built-in usb hub). 

I've connected the devices now as they should be connected, I continue to be able to scan via the main scanner.  

The flatbed unit has an USB ID of its own, lsusb returns:
Bus 002 Device 023: ID 1083:162e Canon Electronics, Inc.

I can also see it in /var/log/messages:
Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: new high speed USB device number 26 using ehci_hcd
Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: New USB device found, idVendor=1083, idProduct=162e
Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: New USB device strings: Mfr=10, Product=11, SerialNumber=0
Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: Product: CANON Flatbed Scanner Unit 101
Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: Manufacturer: CANON

What can we do to make it work? Maybe I need to add the usb id in the canon_dr.conf file?

Cheers,
Milko

Ok- now, in the sane-backends source, edit backend/canon_dr.c

Find the function init_model. In that function, there is a section for
the DR-2510C. Copy that section, and change it to match the DR-3010C.
In your new section, also add this:

s->invert_tly = 1;

Then recompile and reinstall. Hopefully you will be able to scan.
