Hello Sascha, I'm delighted that you have a MX710 series, which we can now debug! scanimage: open of device pixma:04A9175D_20C2C2 failed: Operation not supported scanimage (sane-backends) 1.0.23; backend version 1.0.23 device `pixma:04A9175D_20C2C2' is a CANON Canon PIXMA MX710 Series multi-function peripheral I used the actual pixma backend. Is there any chance to fix the problem. How can I help? Could you read man sane-pixma and use the debug variable to get more output? You'll need to run from the command line: export SANE_DEBUG_PIXMA 3 xsane (or scanimage) If there is a bug in the initialization, then maybe we will need Windows USB sniff results also, but as a first step, we should be able to see if something is clearly wrong or not.

[sane-devel] Canon Mx 700 - Scanbuttons

I got it working, although I am not really sure that it does not contain faults in some corner cases. As we are pretty close to the 1.0.23 release of sane, I will not yet commit the changes to git. It took me quite a while to figure out how the protocol works, so it has taken quite some time before I got something working. Please let me know if you are in a hurry to test before the 1.0.23 release is done. If so, I can mail you a patch to apply on top of the current git. I have only tested this with xsane, as I did not have time to setup scanbd, sorry. It anyhow looks as if sane and printing (bjnp backend for cups) can access the device at the same time: I could print a page while xsane was waiting for a button to be pressed. When the printjob was done, I was able to press the scan button again. Louis P.s. I will push my changes to git as soon as 1.0.23 is released As I was working on the scan button support, I found out that my multi-function (MP980) does support IPv6 (I completely forgot). So I have added IPv6 support for the pixma backend. The changes for button support and IPv6 are now in git. Please test Kind regards, Louis -- sane-devel mailing list: sane-devel at lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-request at lists.alioth.debian.org Hey Louis, very good job. My scanner works now by using the buttons. -- sane-devel mailing list: sane-devel at lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject unsubscribe your_password to sane-devel-request at lists.alioth.debian.org Hey Louis, by using sane-backend(last git) with comandline, my scanner works with the buttons. E.g. scanimage buttoncontrolled=yes But scanbd can't read the buttonstatus. It's a bug or not implemented? All the options are available, but scanbd shows no action by using the buttons. Kind regards? Nelson

Hello, please note that MX710 is experimental in 1.0.23. You need to set the environment variable PIXMA_EXPERIMENT to non-zero, e.g. export PIXMA_EXPERIMENT=1. You will get a corresponding hint after enabling debug outputs on the command line, e.g. with export SANE_DEBUG_PIXMA=1 Alternatively you can use 1.0.24git. Then you don't need to use PIXMA_EXPERIMENT.
