Tim,
Before worrying about the fuser, can you accurately transfer the toner to
the PCB?
I expect that to be the big problem to overcome.

Hi LeMar,
I only have the fuser and power supplys left in the LJ II. I stripped
everything else off, I just wanted to be able to fuse the toner transfer
artwork onto the copperclad instead of ironing it on. I just drive the
SI-7300a stepper driver with a ATtiny2313 running a simple C program. That's
as far as I have gotten thus far. Next, I plan to build a temperature
controller for the fuser, based on the AC power supply from the LJ II. I
will use a microprocessor to sense the temperature and turn the triac on and
off to maintain a selected temperature in the fuser. Hopefully, this will
allow me to fuse the artwork onto the copper by passing it through the LJ
fuser. If there is interest, I will post my methods.

I am interested in the direct printing, this is just an experiment to see if
I can make this concept work for the .062 boards with toner transfer paper.
If the fuser won't fuse the toner onto the copper, direct print won't work
with these printers.
