Hi all, pcb making methode thinkerers,
You all know that the basic concept of a laserprinter is that a laser writes a dotpattern on a electronically charged photosensitive drum. Toner is then attracted to that pattern which is reversed in polarity by the light of the laser. Next the transfer and fusing to the paper gives us the crisp copy's we all like so much.
Now, and this is probably for the engineers among us, could it be possible to make the copper clad board the same photosensitive surface and let the laser write directly on it. Then apply toner on it, and fuse the toner. Then a bath in photo resin desolver where the unprotected surfaces will be cleared from resin and the pattern with toner stays. Then etching and remove toner. For solder mask there are good systems on the market.
Wonder what it would take to alter a laser printer to do something like this?
Would it be possible anyway?
There is a guy who had already rebuild his E 230 lexmark to print on pcb, but he did not used the fuser.
I myself try to do the same with a hp 4100 but all I did so far is broke it down...LOL
I keep you posted of my progress...
