hp 9000 mfp

[Tom]

Hello, got a problem with a machine that I'm only mildly familiar with. I know all the lower end hp printers well, but this 9000 is a bit more intense. Getting a code 50.2, which is a fuser code. Had one laying around that I know works, same problem. After bypassing the side door & watching it, I can see that the heat lamp in the lower fuser is not coming on (heat lamp in upper work fine & cycles properly). I have access to a part machine, so I tried swapping main board, no help. Reconnected all connectors throughout machine looking for loose connection (also jet direct & hardrive) no help. I don't see any blown fuses. Any ideas, I'm thinking power supply next.
