Ok- long scenario..... at customer office machine ran and ran and ran with paper getting to registration and no heat in the fuser. Brang it in, reset sp 5810 and got sc541 continuously(after rebuilding fuser, replacing heat fuse, and thermister) which continuity checks out. We have tried numerous ways of generating other codes, but as soon as we clear the codes, sc 541 comes up almost immediately, even with the fuser completely disconnected and the door open. Sounding like logic to us but just looking for the kiss method that will make me bang my head..
