Hi - I have a Dell laser printer 3110cn, with the error message -077-900 (Paper Jam). However, I cannot see any paper jammed in the machine. Having gone thru' the diagnostics (which I don't really know about) I have "DI-2 H 0" as a message, which I believe indicates an error. I believe this is the exit sensor? Where is this on my printer, and how can I check it?
Many thanks.
