Safety Precautions

For safety reasons, store Print Heads and ink tanks out of the reach of small children.
If a child ingests any ink, consult a doctor immediately.

Do not shake Print Heads or ink tanks.
Ink may leak out and stain clothing or the surrounding area.

Never touch the electrical contacts on a Print Head after 
printing. The metal parts may be very hot and could cause 
burns.

Do not throw ink tanks into fire.
