Mark,
Excellent that you were able to achieve 5 mil! Can you describe in the
details to follow what you did to modify the E260. I know one advantage the
E260 already has over other laser printers is the 1200 dpi resolution.

Last February I suspended my dlp (direct laser printing) experiments
to try to get a modified Epson inkjet to reliably print resist
directly on pcbs. After 6 very frustrating months I decided that I
cannot make it work in any simple reliable manner, though several
people on the inkjet list do seem to be successfully making it work.
For me, the constant effort keep the nozzles clear coupled with the
printer's firmware that required a lot of wasted time and ink and
numerous software issues involving the print drivers made it just too
much "work" for my "one board every so often" needs.
So I've gone back to my attempt to use a laser printer to print toner
directly on pcbs. Here is a link to my latest test board. All the
traces you see ate 10 mil, except for the small group on the right,
which are 5 mil. The scan is not very good, but all of the traces are
intact and full width, except for one small break in one of the 5 mil
traces. <

This board was done with a modified Lexmark E260, but it is NOT
modified as per my earlier documentation. I have incorporated many of
the suggestions made by Jim <

and via private communication, and I think his method is much simpler
and easier to implement than mine. More details to follow.
