[sane-devel] Fujitsu fi-6230 problem with A4 size with flatbed

[Simon Matter]

Hi,

We have several Fujitsu fi-6230 scanners. Scanning A4 size with the
flatbed shows a small black border at the bottom of the page. With one of
the devices the border is ~1mm in size, with the other devices it is
almost invisible.

I scan with

scanimage --source Flatbed --mode Color --resolution 300 -l 0 -t 0 -x 210
-y 297 --format=tiff

The scanner is able to scan 300mm according to the sane backend. However,
this doesn't seem to be the case. Scanning 300mm shows a black line of
~1.5mm and the ~2mm completely white.

To me it seems like the scanner is limited to 297mm by hardware (with one
of our devices it's more like 296 than 297mm).

If that's true then the following patch may make it more correct:

Do others see the same results when scanning 300mm long from flatbed?
