Recently I have bougth an Epson GT-7000Photo scanner. I decide buy this<br>
scanner after searching in SANE list of supported scanners, because I<br>
saw<br>
that the Epson GT-7000 was supported. I need this kind of scanner<br>
because I need <br>
to scan slides and negative films.<br>
<p>
The Epson GT-7000Photo is a standard GT-7000 scanner plus a film adapter<br>
for<br>
slides and negative films. The GT-7000 works fine with SANE, but not<br>
works with the film adaptor. The film adapter is like a cover with a<br>
light projector device, and it is plugged to the scanner with a 8-pin<br>
connector (similar to PS/2 connector). When this connector is unplugged,<br>
all works well, but when I plug it, xsane or xscanimage show an error<br>
message<br>
("failed to start scanner: invalid argument") then not respond and seems<br>
hangs.<br>
<p>
I think that was not difficult to add this feature in SANE epson-sane<br>
driver, <br>
but I don't know about programming drivers for do it for myself. I<br>
believe that<br>
when send an inquiry to the scanner we can determine if the scanner have<br>
the film<br>
adapter connected, and in this case could appear a new option in the<br>
mode menu (<br>
binary, grey, color and FILM) or activate it and send the corresponding<br>
signal to <br>
the scanner to switch-on the adapter light and other signal after the<br>
scanning to <br>
switch-off the adapter light and modifying the scanning area to the film<br>
adapter area (the Epson twain driver for windows works like this. When<br>
it detect the film adaptor, two more scanning modes are activated from<br>
the Epson-twain menu: slides and negative film).<br>
<p>
I'am really grateful if anybody could help me. I have not installed<br>
MS-Windows in my home PC and I don't want do it, I'm very happy with<br>
linux.<br>
<p>
Thank you and excuse me for my very bad English.<br>
