Abstract:
1. A liquid jetting apparatus adapted to receive delivery of liquid from a liquid delivery system, the liquid delivery system having a first delivery system-side terminal, the liquid jetting apparatus comprising: a first apparatus-side terminal adapted to contact the first delivery system-side terminal when the apparatus is receiving delivery of liquid from the liquid delivery system; a contact sensing portion adapted to supply a first electrical signal to the first apparatus-side terminal to sense contact between the first apparatus-side terminal and the first delivery system-side terminal; and a remaining level sensor portion adapted to supply a second electrical signal to the first apparatus-side terminal to sense a liquid volume in the liquid delivery system, wherein the second electrical signal is different from the first electrical signal, and the apparatus is adapted so that the power used by the apparatus to supply the first electrical signal is less than the power used by the apparatus to supply the second electrical signal.
