Xerox 077-900 Paper Jam
What it means
Paper has stopped in the paper path and the sensors can still see it. The code stays on until every sheet is out, including small torn pieces, so open each door the panel points at and check the rollers rather than only pulling the visible sheet.

Common questions
What does the 077-900 error mean on a Xerox printer?
Paper has stopped in the paper path and the sensors can still see it. The code stays on until every sheet is out, including small torn pieces, so open each door the panel points at and check the rollers rather than only pulling the visible sheet.
Is the 077-900 error serious?
Not usually. Codes at this level normally clear once the condition they describe is dealt with, and a printer that carries on working afterwards has nothing further wrong with it.
Different code or problem?
Switch off and unplug a printer before reaching inside it. If a fault involves the power supply or internal electronics, or the machine is under warranty, contact the manufacturer or a qualified technician. Full disclaimer.
