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.
A full step-by-step guide is on the way
We publish guides only after checking each step against the manufacturer's own documentation, so this one is still being written. In the meantime, if the code relates to a jam or an obstruction, switching the printer off, unplugging it for a minute, and checking for anything stuck resolves a large share of cases. For a hardware fault, contact the manufacturer.

Switch off and unplug a printer before reaching inside it.
