In the past few weeks, I have made several updates to the fujitsu sane
backend. I don't really have a good list of testers, so I am putting
out a call for all fujitsu backend users to please try the current
version from SANE CVS.
</PRE>
</BLOCKQUOTE>
I have done some testing with my fi-5110-EOX and scanimage. The backend+scanimage is from CVS as of 5 June.

Particular areas to watch out for:
1. JPEG output is now possible, but will only work with scanimage from
cvs, or some other sane 1.1 compliant frontend
</PRE>
</BLOCKQUOTE>
JPEG output works fine. Is the compression done by the scanner or the backend?
<BLOCKQUOTE TYPE=CITE>
<PRE>
2. The mechanism for determining the color interlace mode is now
automatic, so please see if color scans look weird, particularly if
the scanner has done a color scan in windows without being power
cycled.
</PRE>
</BLOCKQUOTE>
Not really tested, but no problems observed.

4. the scanner device is now named 'fujitsu:model:serial' instead of
the system provided name, if the scanner supports serial number
detection. please verify that the new name actually matches your
scanner :)
</PRE>
</BLOCKQUOTE>
Model and serial is correct.
<BLOCKQUOTE TYPE=CITE>
<PRE>
5. initialization code has changed somewhat, the backend should find
scanners if they are plugged in after the front-end starts (requires
custom daemon frontend to test, I dont know of any in the wild)
</PRE>
</BLOCKQUOTE>
Not tested, would need instructions...
<BLOCKQUOTE TYPE=CITE>
<PRE>
6. please test page-width and page-height support, it seems that some
cheaper scanners don't work.
[...]
Known issues:
[...]
2. page-width and page-height don't seem to work for the fi-5110EOX,
needs software emulation
</PRE>
</BLOCKQUOTE>
As previously found, page-width is ignored. I am all set to test any improvements on this front :-)<BR>
The page-height option works as expected in combination with dfdetect=Length except that dfdiff seems to be fixed at 10mm. A long page (paper jam) occurring as the last sheet of a batch is detected only on the next invocation of scanimage. (May be a limitation of the scanner's detection mechanism, or a scanimage issue?)<BR>
<BR>
Some additional observations about this scanner, for the record:<BR>
<BR>
- dfdetect=Thickness is ignored.<BR>
<BR>
- the overscan option seems to be ignored, although I am not sure I fully understand its purpose. The output looks identical, with no additional space at the top. What is the bgcolor option mentioned in the --help -d output?<BR>
<BR>
- the sleeptimer option works, but does not put the scanner as such into sleep mode. It just dims the scanner lamps after the specified interval if no paper is inserted.<BR>
<BR>
Btw, there seems to be a bit of weirdness going on if these last two options are both present on the command line (individually they are accepted):<BR>
<BR>
$ scanimage -n --sleeptimer=5 --overscan=Off<BR>
scanimage: rounded value of sleeptimer from 5 to 5<BR>
scanimage: setting of option --overscan failed (Invalid argument)<BR>
$ scanimage -n --overscan=Off --sleeptimer=5<BR>
scanimage: setting of option --sleeptimer failed (Invalid argument)<BR>
<BR>
Best regards,<BR>
