Apologies for the long To: list; I haven't been able to determine
whether the problem I'm having is caused by Jeremy Hall's
(experimental) usb-scsi driver, by the Avision SANE backend, or by
something else entirely. If I can narrow it down to one subsystem,
I'll make sure to trim the list.
I'm seeing weird rainbow-colored stripes, repeating about every
half-inch, whenever I scan anything with my HP ScanJet 5300C.
Pictures are available at:
http://www.tir.com/~jonquil/scanner/
scan1-crop is the top inch of the scan, and scan1 is the entire image.
I can get these stripes to go away by plugging the scanner into a
Windows machine, using HP's software once, then plugging it back into
my Linux machine. That points to an initialization problem, but I
haven't seen anybody else complaining about this scanner exhibiting
this problem...
I'm using Jeremy Hall's experimental usb-scsi driver patch (from
Tobias Nijweide's page at:
http://www.neatech.nl/oss/HP5300C/
) against a 2.4.0-test12 kernel, and the Avision SANE backend, with
the patches from Tobias' page.
I've tried the --quality-cal option to SANE, and I've tried at various
resolutions, and at color, greyscale, and line-art mode, and all have
the same effect (except that the rainbow colors are grey or black in
non-color modes).
Has anybody seen similar problems? Or does anybody have any ideas
about how to go about troubleshooting/fixing this?
I have about a week to figure this out; after that, I'll just return
the scanner, and pay closer attention to model numbers. :-)
Thanks!
