Well, I have no idea why changing your password would affect it this way. the code you're experiencing is a fuser warm up error, due to blown fuse, thermostsat, possible power supply prob...regardless, it can only be reset by a service tech in service mode once the problem is fixed. Sorry.

Relates to fuser unit. Needs to be reset from service mode.
