I have done some testing with my fi-5110-EOX and scanimage. The backend
+scanimage is from CVS as of 5 June.

JPEG output works fine. Is the compression done by the scanner or the

Not really tested, but no problems observed.

Model and serial is correct.

Not tested, would need instructions...

As previously found, page-width is ignored. I am all set to test any
improvements on this front :-)
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?)

Some additional observations about this scanner, for the record:

- dfdetect=Thickness is ignored.

- 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?

- 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.

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

$ scanimage -n --sleeptimer=5 --overscan=Off
scanimage: rounded value of sleeptimer from 5 to 5
scanimage: setting of option --overscan failed (Invalid argument)
$ scanimage -n --overscan=Off --sleeptimer=5
scanimage: setting of option --sleeptimer failed (Invalid argument)
