Well I finally got around to picking up a used HP2015dn printer. I was looking forward to experimenting with making some boards. Unfortunately the printer is not working. An online search reveals that this printer has a history of cold solder joints on the formatter pcb. There is a DIY fix that I am going to try. Using a household oven as a solder re-flow oven. I can also buy a new board or refurbished board. Anyone else experience this problem with their HP2015 printer?
