One of the wards in my stake had an HP P2015 printer (issued by our FM Group about 15 months ago). All of a sudden, the Paper Jam alert light went on, and it refused to print. I tried every technique I know of to reset this condition:
- I checked the paper path for any jams, or even tiny loose scraps of paper. There were 5 places to look, and I checked them thoroughly.
- I turned the power off and back on.
- I did a cold reset.
- I did a hard reset.
So now comes the weird part. With further research, I found a forum thread which proved to be the gold mine at http://www.fixyourownprinter.com/forums/laser/48992#47. It's a long thread, but quite a ways down the thread is the post I linked to, which recommends baking the formatter board to repair a cold surface mount solder joint.
So I had nothing to lose, because I had proven that the formatter board was bad. So I:
- Preheated my oven to 350F.
- Carefully removed the formatter board (disconnect the 5 connections, and remove 4 screws)
- Removed the piece of plastic by the DIMM slot.
- Put the formatter board on a cookie sheet, propped up with some pieces of ceramic.
- Baked it for 8 minutes.
- Let it cool for an hour or so (it was completely cool).
- Put it back in the printer (replaced 4 screws, carefully reconnected all 5 connections)
- Plugged in the printer
- Turned on the power and ...
- It worked!
