Paper jam (077-104) on Dell 2130cn printer when Duplexer installed.
I just installed a duplexer for the Dell 2130cn printer I have. It paper jams all the time with the duplexer installed with a 077-104 error. Without the duplexer everything works fine. I re-seated the duplexer and fuser assemby without any change. The duplexer shows up on the status when installed. Is this a case of just a defective duplexer?
