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.
