<P>
|
|
Apologies for the long To: list; I haven't been able to determine
|
|
<BR>
|
|
whether the problem I'm having is caused by Jeremy Hall's
|
|
<BR>
|
|
(experimental) usb-scsi driver, by the Avision SANE backend, or by
|
|
<BR>
|
|
something else entirely. If I can narrow it down to one subsystem,
|
|
<BR>
|
|
I'll make sure to trim the list.
|
|
<BR>
|
|
<P>I'm seeing weird rainbow-colored stripes, repeating about every
|
|
<BR>
|
|
half-inch, whenever I scan anything with my HP ScanJet 5300C.
|
|
<BR>
|
|
Pictures are available at:

<P> <A HREF="http://www.tir.com/~jonquil/scanner/">http://www.tir.com/~jonquil/scanner/</A>
|
|
<BR>
|
|
<P>scan1-crop is the top inch of the scan, and scan1 is the entire image.
|
|
<BR>
|
|
<P>I can get these stripes to go away by plugging the scanner into a
|
|
<BR>
|
|
Windows machine, using HP's software once, then plugging it back into
|
|
<BR>
|
|
my Linux machine. That points to an initialization problem, but I
|
|
<BR>
|
|
haven't seen anybody else complaining about this scanner exhibiting
|
|
<BR>
|
|
this problem...
|
|
<BR>
|
|
<P>I'm using Jeremy Hall's experimental usb-scsi driver patch (from
|
|
<BR>
|
|
Tobias Nijweide's page at:
|
|
<BR>
|
|
<P> <A HREF="http://www.neatech.nl/oss/HP5300C/">http://www.neatech.nl/oss/HP5300C/</A>
|
|
<BR>
|
|
<P>) against a 2.4.0-test12 kernel, and the Avision SANE backend, with
|
|
<BR>
|
|
the patches from Tobias' page.
|
|
<BR>
|
|
<P>I've tried the --quality-cal option to SANE, and I've tried at various
|
|
<BR>
|
|
resolutions, and at color, greyscale, and line-art mode, and all have
|
|
<BR>
|
|
the same effect (except that the rainbow colors are grey or black in
|
|
<BR>
|
|
non-color modes).
|
|
<BR>
|
|
<P>Has anybody seen similar problems? Or does anybody have any ideas
|
|
<BR>
|
|
about how to go about troubleshooting/fixing this?
|
|
<BR>
|
|
<P>I have about a week to figure this out; after that, I'll just return
|
|
<BR>
|
|
the scanner, and pay closer attention to model numbers. :-)
|
|
<BR>
|
|
<P>Thanks!
