epson2 backend / Epson Film Scan 200 / TCP-IP support

 Hello,

   after many months of tests I just discovered that the
Epson FilmScan 200
 hangs if the first command that is sent is a reset (doh!).
 
  Resolving this issue enabled me going further in the
development
 of the epson2 backend.

 I've started the development from the epson backend and
restructured
 it in order to better support different scanners on
different transport
 layers, like tcp/ip.

  My plans are to fully support the FilmScan 200, including
the
 Advanced Photo System loader, and other epson scanners.

 I will be able to test on Epson CX11NF and GT-7000 photo
 any I'm searching for interested people that can both
 help in development and/or test with other epson devices.

 I'm particularly interested in scanners equipped
 with ADF and/or backlight units.

 Hardware donations will be appreciated 

  Furthermore, my backend will be one day able to support
 tcp/ip communications with the CX11NF. I'm currently
 able to detect and setup the scanner properties and
 still have to write the actual scanning routines.

I've got Perfection 2580 Photo. The thing that doesn't work
now is automatic 
film transporter.
I'd be glad to help you in testing new backend.

Sorry but that will not work.  The Perfection 2580 PHOTO and
FilmScan
200 use different protocols.

The reason that the epkowa backend can support this model is
because
it allows the use of the non-free binary-only plugin that
converts
between the protocols.

Hope this helps,

 d'oh! one less tester for me! 

 thanks anyway for your offer, Jeroslaw.

Olaf, saying 'this' You mean FilmScan 200 or Perfection 2580
Photo?

AFAIK Perfection 2580 Photo works with epkowa and snapscan
backends. But 
neither of them supports transparency unit.

Sorry for not being clear.
I meant to refer to the Perfection 2580 PHOTO.

True, the 2580 can be used with the snapscan backend as
well.  The
epkowa backend should let you select the transparency unit
(TPU),
IIRC.  However, the automatic film loader (AFL) is *not*
supported.
You will have to move the transparencies by hand yourself
:-(

Hope this helps,

Unfortunately, it is impossible. AFL does not allow to move
the film by hand.
When I try, film slips into the scanner on about 5-7 mm, and
then refuses to 
go deeper.

Getting know SANE to be able to develop support for AFL on
that device is on 
my TODO list for at least two years. Unfortunatelly there's
always "more 
important thing to do" :(
