[sane-devel] Re: sane-devel digest, Vol 1 #251: HP Scanjet 7400 C
Sat, 03 Apr 2004 15:58:59 +0530
I had a similar problem (black scans with HP Scanjet 7400C; OS: Mandrake
Linux 9.2). I had also reported this to the list.
I tried patching the source and recompiling as suggested below. The
compile succeeded. Sane detected the scanner (which is now a
scsi-generic scanner instead of the earlier usb scanner).
However xsane hangs on clicking the button "Acquire preview".
What have I got wrong?
Will appreciate help on this.

It looks like you run a very old version of SANE/Avision. Just update
It should just work then. (incl. ADF and 16 bit scans)
