The only thing to keep in mind with this stuff is that the copper has
to be very clean for it to be effective. No fingerprints, etc.
We've talked about your coming out here for some hacking. Bring some
boards with you and you're welcome to try it out.

- I don't etch my own cards very often any more, but I ones I do, are also done with the laser toner method. I used to use glossy photo paper, but switched to using a glossy page ripped out of a magazine, which works better for me. I try to find a page with a lot of white space. You don't want to know about how I keep the etchant warm. :-)
Actually I was thinking of Goo Gone, but that is also oily.

Look for the rubber paper pickup roller via a Web search, various "fix your own printer" companies sell them. The rollers simply wear down with time and (with effort) can be replaced. There may be other parts and so there might be a "kit". None of this is from HP.
