While I'm still going to get a cheap laminator, and like the Reynolds on
basic testing, all the little extras and gotchas make me really want direct
printing.
After disassembly and a lot more looking, the initial feed, drum/transfer,
and pressure rollers may all be in line with the cartridge installed despite how
the service manual diagram looks, if not it's close and shouldn't take much for
a mod. Bet the .025" blanks I have coming could handle any necessary bend. The
exit roller isn't in plane, but you could really just let the board drop after
the fuser, and just hack out the exit area. Only other thing is the fuser is
tilted slightly over the pressure roller, expecting the paper edge to drop
slightly and then get rolled back up by the pressure roller as it enters. If
the board can feed reasonably straight from entry, drum, to pressure then it'll
be easy enough to adjust the fuser angle.
If nothing else works, I will totally hack out a fuser section. Since it
prints to metal, the input and drum sections should print, and then feed it
straight to a laminator's rollers. Would rather use the built in fuser, but it
is not roller based instead having a stationary strip and a 'rolling' teflon
sleeve. May cause smearing if that sleeve won't roll properly over the thick
stock since it'll keep it away from the pressure roller at the edges. A true
heated roller would work there if it won't.
Will take some major cutting to cut the paper entry section to let a board
come in straight though, it's got near vertical feed and probably goes through
60 deg bend to the printing plane. Just plastic so not impossible just will
take some sawing. Hmm, actually though a single saw blade pass at the right
place, depth, and angle might do it for a board entry slot, so maybe just a good
table saw with fine blade would be enough.
