Safety precautions

Label	Explanation

	When the printer is printing, the printhead carriage travels back
	and forth across the substrate.

Beware of this moving part.

Emergency stop buttons

There are four emergency stop buttons distributed around the printer. If an emergency occurs, simply push one of the emergency stop buttons to stop all printing processes. A system error message is displayed on the front panel, and the fans turn at maximum speed. Ensure that all emergency stop buttons are released before restarting the printer.
