You can also log onto the printer's web interface and change the behavior settings. On 'low toner' set it to continue printing. I got another couple of hundred pages before the cartridge ran dry.

Is this possible with this model? It only has USB, no ethernet. In any case, there are probably also ways to change these settings via push-button acrobatics.
Pushbutton acrobatics, indeed look here
