I entered a bug in the tracker and got a comment by Paul Menzel <https://alioth.debian.org/users/paulepanter-guest/>: "I think the tracker is not used a lot anymore by the current developers. Please bring your issue up to the sane-devel list"
As the problem is absent in sane 32-bit, and permanent in 64-bit, it could well be a development issue. in the tracker it reads: [#314019] my scanner has a problem in the 64-bit systems but works fine with the same systems in 32 bit Scanning several pages with my flatbed scanner works fine for the first two pages; the subsequent pages will have wide coloured vertical bands in the background (black for a grayscale scan). This is true for the 64-bit versions of Fedora 16, 17 and 18; with the 32-bit versions of the mentioned distributions there is no problem. Scanning using xsane or simple-scan produce both the misbehaviour. After leaving the graphical fronted and it's restart one can again scan two pages properly. Version details are (here with Fedora 17): Linux 3.7.3-101.fc17.x86_64 sane-frontends-1.0.14-14.fc17.src.rpm sane-backends-1.0.23-4.fc17.src.rpm idem libs and drivers-scanners scanimage -L device `plustek:libusb:003:003' is a Epson Perfection 1250/Photo flatbed scanner joined the scan of an empty, white but not very clean, A4 sheet, scanned as n? 3 after startup of xsane. The workaround is to stay in a 32-bit OS submitted also at bugzilla.redhat.com for fedora with the id 909551 comparing the joined file with the one joined with 304296 (08/04/2007 - not solved yet) and the problem description there with this one, the similarity is striking: the coloured bands are similar OK with the 32 bit OS Gentoo, problem with the same OS in 64 bit but the scanners are of different models (but may use the same chip) the OS's are different distributions Gerard van der Veen -------------- next part -------------- An HTML attachment was scrubbed...
