Two posts in one night… man when it rains it pours I guess…

I had another update on the PCB etching.  Once again we failed.  This time I ordered some Toner Transfer Paper http://www.amazon.com/Toner-Transfer-Electronic-Prototype-Sheets/dp/B00B0ZDXB2/ref=sr_1_1?ie=UTF8&qid=1363659597&sr=8-1&keywords=toner+transfer+paper.  The failure was not with the paper though.  My friend tried to print the schematic onto the paper and the toner would not stick.  Most of the toner came right off.  Frustrated I call another friend with a laser printer to try his and it was slightly better but still terrible.  Finally I took the output pdf to work and printed there and finally success.

The only thing that I can think is that both printers that failed were color laser printers.  The first was a konica minolta 2500 and the other was as xerox 7500 ??? (Ill get the exact number soon).  The one at work was not a color laser just good ol b&w Xerox Phaser 3600 http://www.support.xerox.com/support/phaser-3600/support/enus.html?operatingSystem=winxp&fileLanguage=en.  The jury is still out on why the toner would not stick more investigation is required I guess.

Here is the schematic printed on the TTP ready from transfer.  Attempt number 3 will be coming soon.
