http://www.tonepad.com/photoessay.asp?photoEssayID=10&sequenceNo=4 Im this far..Ok - so i tape this blue pnp to the paper..then do i place it into the feed paper end of the copier?- its sucks it in.??? I dont get it.. I know i need to get the image printed onto the pnp- i just dont see it. I assume you place the image from the printed out layout on the copier and close the lid- but that would print it onto paper..so I would need to replace the feed paper with pnp blue..but why tape it. I really hope im not the only one trying to figure this out.

any clarification?

The method described is intended to save you from wasting a whole sheet of PNP on a single PCB. First, take a blank sheet of paper and put an X in one of the top corners. Put it into the tray that the paper is fed from and remember where the X is. Then, print out the PDF file onto the regular paper without PNP blue on it. Then, take a square of the PNP slightly larger than the PCB transfer portion of the PDF you just printed out and tape it dull side up to the paper. Place the paper back into the tray that the paper is fed from and make sure the X is located in the same position it was before. Print it again, and the PCB portion of the PDF will print onto the PNP blue sheet instead of the paper. The point of the X is to make sure you feed the paper in the same direction and same side up each time so that registration (read: way things line up) is correct. Using this method, you can get a number of PCBs from a single sheet of PNP blue, so you save lots of money in the long run.

Forgot the copier specific part. If using a copier, you'd take a copy of the PDF you've already printed out and place that in the top part. You'd put the X on the blank sheet in the feed tray, make an initial copy, tape on the PNP, replace the "frankensheet" in the feed tray and make a second copy. I have a laserprinter at home, so I've never tried it that way, but I'm sure it works.

SO the 1st part is using a lazer printer..than makes sense now..Thanks!!!!

People say laser printers work well.  I always use the old toner transfer copier at work.
