Hello,
|
|
<BR>
|
|
<P> Thanks for setting me straight on the scsi id's and the device
|
|
<BR>
|
|
file names, Doug. What's really wierd is that, if I make the
|
|
<BR>
|
|
link /dev/scanner -> /dev/sgb (i.r., consistent with what
|
|
<BR>
|
|
scanimage -L says), scanimage -L fails with:
|
|
<BR>
|
|
<P> [s9036] sense_handler() : sense code = f0
|
|
<BR>
|
|
Segmentation fault
|
|
<BR>
|
|
<P>So, I just removed the link and at least scanimage seems
|
|
<BR>
|
|
to work. The SANE programs seem to be getting information
|
|
<BR>
|
|
from the scanner, so maybe the SCSI communication is working
|
|
<BR>
|
|
OK.
|
|
<BR>
|
|
I turned on debugging (export SANE_DEBUG_EPSON=255), and
|
|
<BR>
|
|
have found that, while the final error message after trying
|
|
<BR>
|
|
to do a scan is:
|
|
<BR>
|
|
<P> [epson] option: fatal error
|
|
<BR>
|
|
<P>there actually seems to be a failure before this. What appears
|
|
<BR>
|
|
to happen is the following call sequence:
|
|
<BR>
|
|
<P> sane_read -> read_data_block -> receive
|
|
<BR>
|
|
<P>after which the message:
|
|
<BR>
|
|
<P> [epson] fatal error - Status = a2
|
|
<BR>
|
|
<P>gets reported. I am a little anxious to get this scanner working
|
|
<BR>
|
|
and would be very grateful if someone would be kind enough to
|
|
<BR>
|
|
step me through the debugging - or at least give it a try. The only
|
|
<BR>
|
|
specs for the GT8700 I know of are located at the web page:
|
|
<BR>
|
|
<P> <A HREF="http://www.i-love-epson.co.jp/products/scanner/gt8700/87003.htm">http://www.i-love-epson.co.jp/products/scanner/gt8700/87003.htm</A>
|
|
<BR>
|
|
<P>This is in Japanese but probably not so hard to figure out (nothing
|
|
<BR>
|
|
about the communication anyway, just the hardware specs - denisty, etc).
|
|
<BR>
|
|
I can translate it for you if need be. One thing that worries me
|
|
<BR>
|
|
is that the input/output is claimed to be 14-bit, different from
|
|
<BR>
|
|
most of the other scanners.
|
|
<BR>
|
|
Well, thanks in any case. Cheers,
|
|
<BR>
|
|
<P><PRE>
