Lexmark 31.xx Defective or Missing Cartridge
What it means
The printer cannot read the cartridge that is fitted, or none is fitted at all. Take the cartridge out, check that every piece of orange packaging and tape has been removed, then refit it firmly. A cartridge that still will not read after that is usually the problem.

Switch off and unplug a printer before reaching inside it.
