I understand some french - it seems the article is a well written step
by step instruction to get the scanner working.
There are currently two issues that make the installation of the 1670
1) The scanner doesn't use the epson backend but the snapscan backend
2) The scanner needs a firmware file entry in snapscan.conf
The first point can't be helped, but I think it's clearly documented
on the SANE webpage, the Epson backend webpage and the snapscan
The second point is a pain, but I really have no idea how to automate
the setup without getting into conflict with copyright issues from
the scanner manufactures. However, I hope the procedure for the
firmware download is clearly documented on the snapscan website. If
you think the documentation can be improved please let me know.

The 1670 certainly doesn't behave like other epson scanners, that's
why it's supported by the snapscan backend. A number of scanners that
are supported by the snapscan backend have a transparency adapter (I
own an Acer 620UT with transparency adapter). These adapters are
supported by the snapscan backend and usually work well. Up to now
all scanners supported by the backend use the same mechanism to
enable the transparency adapter. The problem now is why this
mechanism doesn't seem to work for the 1670. However, I still don't
have any accurate error description as to what is wrong when using
the transparency unit.
