That's pretty decent; got any pictures? I've stayed at 6-12mil
trace/6mil clearance on my boards. I've seen when doing 4" x4" or
bigger that I needed to surround the fine traces with other toner to
keep the stock from peeling off the super thin lines. You must of hit
on an even better toner/printer combo. What printer/toner
manufacturer are you using? 1200dpi?
I haven't had any TT magazine paper jams yet in my HP 5L sending
magazine pages through the envelope feed (1 sheet/time). I was
cutting the paper with a paper cutter at first; now I just rip it out
of the magazine and feed it through directly.
I did a write up of the process a while ago. Anyway it shows a few
pictures of what I've done on it. It was cited on this thread
earlier:
