Re: [sane-devel] Sending confirmation about the pixma backend
Hi Rogério, I opened a merge request for your issue here: https://gitlab.com/sane-project/backends/merge_requests/213 Please build SANE from source as described in INSTALL.linux (http://www.sane-project.org/docs.html). If this is working, please pull recent code from git ($ git pull), checkout our test code ($ git checkout pixma/e4200-adf) and build SANE again. Then ADF should work. Please report your results in the merge request. Many thanks for your help.

Re: [sane-devel] Sending confirmation about the pixma backend
Dear Rolf and other developers,
I'm resending the message below because it was potentially not allowed to
reach the list (due to the attachment inflating its size).
The comments below (of course) still apply.
Thanks,
Rogério Brito.

Thanks for the feedback. They both seem like considering as fine
replacements to this current Canon E4210, especially considering their
optical resolutions.
Unfortunately, it doesn't seem like I can get the HP C309a in my
country. :-( The X576dw, OTOH, is beyond my budget. :-(

Like the first one from HP, and according to the specs on Canon's site, it
seems to be capable of amazing high resolutions and it is not that
expensive (this one I can find on my local market).

I will keep this in consideration for a future purchase for my parents (they
will need an all-in-one device soon, it seems).
Thank you very much for your recommendations,
Rogério

Re: [sane-devel] Sending confirmation about the pixma backend
Rogerio,
I use a HP C309a and X576dw (fast scanning) daily and reliably with their
hplip drivers and gscan2pdf. No issues.
I needed the Canon LiDE220 as a scan-only device (work on desk) and HP's
ScanJets are a bit expensive. I would expect the drivers to be working well
on that device too.

Re: [sane-devel] Sending confirmation about the pixma backend
Hi Rogério, I can see an error response in your log file. To fix this I need an USB snoop file from Canon's ScanGear Software. You can use wireshark for snooping (to enable USB support read this: https://wiki.wireshark.org/CaptureSetup/USB). Many thanks for your help.
