Hello,
<BR>
<P>&nbsp;&nbsp;I'm new to sane so I apologize if there is something obvious
<BR>
I missed in the FAQ and installation instructions. My situation
<BR>
is as follows:
<BR>
<P>&nbsp;&nbsp;&nbsp;I run a Redhat 6.2(SMP) system and recently bought an Epson
<BR>
GT8700 scanner. I realized this model isn't officialy supported,
<BR>
under SANE but was encouraged by the &quot;supported Epson scanners&quot;
<BR>
thread in this mailing list. This scanner has a SCSI interface
<BR>
which I have connected to my PC's on-board Symbios SCSI.
<BR>
I set the sg buffer in /usr/include/scsi/sg.h to the 130560 size
<BR>
suggested in the sane-scsi man page, and recompiled the
<BR>
kernel, although I later learned that this probably wasn't
<BR>
necessarty for my 2.2.14 kernel(?). In any case, the sanner
<BR>
shows up in the boot message.
<BR>
&nbsp;SANE (and xsane) compile with no reported problems.
<BR>
I try the following scanimage comands:
<BR>
<P># scanimage --list-devices
<BR>
device `epson:/dev/sgb' is a Epson GT-8700 flatbed scanner
<BR>
<P># scanimage --device epson:/dev/sgb --help
<BR>
Usage: scanimage [OPTION]...
<BR>
<P>.... a long list of options, ending with:
<BR>
<P>List of available devices:
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;epson:/dev/sgb
<BR>
<P>(the scanner makes a brief but reassuring noise when I
<BR>
run these). However, if I try to preview using xscanimage
<BR>
or xsane, I get the error message
<BR>
<P>Error during read: Invalid argument
<BR>
<P>in a Gtk box, and
<BR>
<P>[epson] option: fatal error
<BR>
<P>in my terminal window. Needless to say, I am unable to
<BR>
acquire any scanned images, preview or otherwise.
<BR>
<P>&nbsp;Can anyone please offer some suggestion as to how
<BR>
to proceed in order to overcome or diagnose this
<BR>
problem? Thanks,
<BR>
