This is an official utility tool used by technicians to calibrate hardware, change regional codes, and reset internal counters (such as the waste ink pad counter).

The printer has an internal counter that calculates how much ink is purged into the pad. Once this counter hits 100%, the printer locks itself to prevent ink from spilling on your desk, even if your sponges aren't physically saturated yet.
