Ever have an epic failure in an electronic device which you simply couldn't resolve and knew it would cost more to get it fixed than to have the device repaired?
Even as an IT professional, this will occur once in a while. Sometimes you're given a 'bricked' device to dispose of or fix.
One client of ours had a failed printer, and after much poking, prodding and analyzing we simply couldn't get a response from the printer which was recognizable in the support documentation. The light status was completely wonky and in order to get further support assistance, we'd have had to spend money. However, John got online and did further due-diligence and discovered that this particular printer has a very interesting resolution for the symptoms we were seeing.
The printer is a HP Laserjet P2015dn. Apparently the formatter board on this model often fails as the lifetime of the machine progresses. We found some suggestions that you can remove the circuit board from this thing, and bake it in the oven for 8 minutes at 350 degrees, it would fix the problem. The heat softens the soldering so that it flows just enough to improve the connection of the circuitry. John rolled up some aluminum foil and placed it on the four points of the board to keep it off of the cookie sheet itself.
Yesterday we were laughing about this solution he found online. I thought to myself: "No way: this sort of thing has got to be a prank." I was wrong! Today I re-attached the formatting board he baked last night, and the printer is now functioning as expected. Go figure.
