[sane-devel] Lexmark CX510de printer / scanner
Bonjour, When I use xane with my HP Scanjet G4050 scanner, it is possible to define a frame (dot lines) in the preview window before scanning. When I use xane with my Lexmark CX510de scanner, it is impossible to select a frame in the preview window (no dot lines), I am obliged to scan the full image. How can I solve this problem ?

[sane-devel] Offset problem
Bonjour, I use HP Scanjet G4050 scanner with Mageia Linux 6 / xsane version 0.999. When I select a frame in the preview window, the resulting image is correct for a 100 dpi resolution. For a 200 dpi resolution there is a negative vertical offset, I mean about 2 mm are missing at the bottom of the picture (about 2 mm added at the top). For 200, 400 and 600 dpi resolution there is a positive offset, I mean about 2 mm are missing at the top of the image (about 2 mm added at the bottom) What can I do to solve this problem which is very annoying. I do not want to have to reboot to Windows ... When I use the scanner with Windows (in the same PC), with the HP software or with the Windows scanning software the result is correct.

[sane-devel] Adding support for scanner
I have a Canon imageCLASS MF416dw that does not appear to be supported by sane. How can we get it added? I'm happy to do whatever legwork I can. -- *** * John Oliver, RHCE, LFCS http://www.john-oliver.net/ * * * *** -- sane-devel mailing list: sane-devel@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-requ...@lists.alioth.debian.org

Re: [sane-devel] What does basic support mean on the supported devices page for Plustek Opticbook 3600?
Le 09/04/2018 à 14:50, Olaf Meeuwissen a écrit : The meaning of "basic" and other status classifiers are explained in the Legend at the bottom of the page. There's a link near the top, BTW. Thank you very much. for the latest information. FWIW, the support status of the scanner you mentioned has *not* changed. What is the reason that make a device support to basic? The lack of time or the lack of documentation? In another word, if I tell to my user that his scanner works, if some feature is missing, could we collaborate together to implement them or is it impossible?

[sane-devel] What does basic support mean on the supported devices page for Plustek Opticbook 3600?
Hello all, I'm trying to help a visual-impaired person that wants to switch to GNU/Linux. He has a Plustek Opticbook 3600 and I found on this page: https://www.chiark.greenend.org.uk/doc/libsane/supported.html that the support of this device is noted as basic but honestly I don't understand what this mean. What does basic support for such device mean ? Is the page I've found correct to check if an hardware is compatible with Sane?
