Xerox 016-799 Invalid Print Job
What it means
The machine received a job it could not interpret. It is almost always a driver problem rather than a fault: the wrong print driver for the model, or a job sent in a page description language this machine does not support. The printer itself is usually fine, and the same document prints once the right driver is used.
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. 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.
