Dear Sane-developers! I'm currently in possession of a Canon i-SENSYS MF211. It's a 3-in-1 machine that can print, copy and scan. The device supports both Wifi, Ethernet and USB. I'm currently using USB.
I'm trying to get it to work under Linux (Mageia 5, i586). Printing (and copying) works fine, but not scanning. On the Sane "supported devices" page it is marked as "untested, testers needed!". It is supposed to use the Pixma-backend. I've tried both Sane backend version 1.0.25 and a more current snapshot from 20th of May 2016 (both compiled from source with no alterations by me). Both versions generates the same errors, although the scanner finishes much faster when using the snapshot. The scanner is recognized by sane-find-scanner, and when I try to use scanimage I do actually get an image, but only the first lines of the picture. When running the program with SANE_DEBUG_PIXMA=21 I notice three error messages: "WARNING: Unexpected result header", "ERROR: ETIMEDOUT" and finally " WARNING:image size mismatches [pixma] 1683840 expected (877 lines) but 30720 received (16 lines) [pixma] pixma_read_image(): completed (underrun detected)" The error messages are very consistent, however when scanning in grayscale-mode Sane only receives 8 lines: "561280 expected (877 lines) but 5120 received (8 lines)" I would like to help debug the problem, but I'm not familiar with the pixma-protocol, so I need some ideas. Should I post the complete dump of debug-messages as inline text to the mailinglist (default scanning-mode produces a 132 KB textfile of debug messages) ?
