Now, here's what, having spent a good part
of my time with USAF receiving faxes at the
Weather Central at Andrews AFB in 1949
and other places later, here it is:
The TXC-1 has a small stylus that burns the
cover from the fax paper that's on the drum.
We used two kinds of paper, Teledeltos and
not-teledeltos.  Teledeltos stunk when it was used,
but it could be copied in a gelatin copy machine.
The other paper was also white, but had a thin
coating of starch.  It did not smell.   It was all
12 by 18 size.  Drums on SSB radio circuits
turned at 60 RPM, drums on landline circuits
turned at 120 RPM.   Trivia:  At the HF receiver
site, where the operator had to keep a very
close eye on the incoming signal, the plain paper
was used.  The fax signal then went to the weather
people nearby who used Teledeltos to meet their
needs.  When the weather people had a problem
with their machines, we copied with Teledeltos,
and sent it to them by courier.
The TXC-1 could send and receive shades of
gray in black and white, but weather maps were
all black and white.
