R200 does the same thing now and then, especially if the paper is
curled a bit in the wrong direction. I think the paper path doesn't
100% keep the paper away from the head at least on this one..

Yep looks like why it manages to stand up to etchant ok. I have some
liquid ceramic paint from doing the house, like cold cream in
consistency. Thinned out with water it'd probably work through a print
head, and leaves a good film even when very thin. Meaning to check it
for etching, but too many other things to do so haven't etched anything
for a month or two.. Got too many boards to build and layouts to finish
already on deck..

Almost sucks selling things, even when you make $100 on $20 of parts.
Once it sells then you actually have to build the damn things, it's
almost a job.. :) Kind of fun, but can't wait to have an employee to do
this part..
