Currently I'm working on a Xerox 7400dn with a fuser jam whenever the printer is duplexing, and occasionally when printing single sided. The jam occurs after the fuser in the exit gate assembly. The exit gate solenoid fails the on board solenoid test available. \n\nA previous technician has replaced the fuser and the duplexer, thinking these to be the problem. After running the tests on the solenoid I ordered an entire exit gate assembly and replaced that. Even after replacing the whole exit gate assembly (which includes a nice and new exit gate solenoid) the exit gate solenoid fails testing.\n\nI'm really not sure where to go on this now. Any help would be appreciated.
