I am working on a estudio 35 with a close front cover error. if you open the front door and close it it says close front cover. replace and checked all switches, power supply, main pcb, fuser.
Any help would be great.
check the wiring for the door switch, I had an issue with one of those.
check the wires ones by one with a multimeter, or better yet get the wiring from another machine and swap it.
Linear Mode
