I found a user level description of the Epson GT80FLU Transparency unit
(see http://www./xs4all.nl/~labrat/downloads/es600cua.pdf ) for some of
the GT series and it declares a lot of the difficulties:
1. This TPU is not just a hood with a lamp; it contains a carriage with
either a lamp or a sensor

Pin 11 can be traced to the chassis at 0 ohms - lengthy route but

You are very brave :-)
I would not short two contacts without a resistor. For the first
attempt I would use something like 1K. I doubt that any of the 24V
lines are involved in sensing the TPU. If the 1K resistor does not
give you any result, go down to 0.5K.
How do you test if the TPU is re

High is 5V for TTL electronics, low is <1V. 24V is goodbye :-(

Hello again,
It's going to be some retro demonstration if this goes to work. Thanks
for all your replies.
After some fiddling with the configuration files I found the number that
defines "Blindfarbe" (shines just one of the three monochrome tubes in
the gt-8000's sensor) for BW modes can be set 0

A "real" TPU is just a lamp behind some ground glass (or translucent
plastic), so
there is not "projection" involved: The sensor scans the illuminat4ed
negative or slide
directly.
Have you checked out the link to the message from the guy who is using a
lightbox on his Perfection 1200? He had som

Hello,
Although not a SANE user, I'd like to try and post a question about a
hardware experiment on a Epson gt-8000.
It occurred to me that if it is possible to project a negative on the
scanners glass pane using a slide accessory, it might also work to use a
photo magnifier (I mean the thing
