ABSTRACT:
Ink is recirculated from a reservoir (624) through an ink ejection head (100) and back to the reservoir (624) while it is being heated prior to actual printing to purge air from the ink and prevent erroneous ejection. The heat (100) has a nozzle assembly formed of a thick glass plate (184') and a thin plate (190') of monocrystalline silicone which is bonded to the glass plate (184'). Ink ejection ports (191') are etched through the silicone plate (190') which communicate with an ink chamber of the head (100) through passageways (185') formed through the glass plate (184').
