…both of my P2015 have gone completely insane. They stopped working like a printer at all. Random error light codes; changing error codes as time passes, etc.... I baked one of the printer’s system boards in a pre-heated oven at 400 for 7 minutes. It works perfectly now. The other was squeeling at times too, can’t wait to try it again tomorrow…

PS By system board I mean the little circuit board with 5 or so connectors/cables on the left side of the printer, remove the left plastic panel and you will see it…
