Technote: HP LaserJet P2015dn Formatter Circuit Board Repair
HP LaserJet P2015 printers often fail due to faults in the formatter circuit board. Your laser printer will have the paper jam light on even if there is no jam, and will sometimes have the toner low light on as well. The link lights on the ethernet jack won't turn on either.
I found discussions on how to fix your HP LaserJet P2015dn laser printer and one technique is to bake the formatter cicuit board in the oven for a few minutes. Typical instructions say 350 degrees Fahrenheit for 8 minutes but I used about 400 degrees Fahrenheit for 4 minutes. This will melt and reflow the solder and often works. NOTE: as with any information on the Internet, follow this procedure at your own risk. It may ruin your circuit board so consider it a method of last resort and do not proceed unless you can afford to have it fail. But with that said, it worked for me and my printer is back in action after a few minutes of work.
Note: Fourteen months later my printer began to have problems again so I repeated the procedure and the printer is working again. This time I baked the formatter board at 400 degrees Fahrenheit for 8 minutes. That discolored the board and created a strong smell so next time I would bake it for less time.
