Ink jet printer with bubble driven flexible membrane

摘要: An apparatus is disclosed for propelling ink droplets from an jet nozzle which uses expanding bubble as a driving mechanism. Unlike other thermal devices, the itself not used to provide bubble. Rather two fluid system whereby flexible membrane maintain separation between working and ink. A thermally created in distends causes on side of be expelled orifice. The direct physical contact with surface bubble-generating resistor quantity lies pockets by roughening or resistor; alternatively, may provided particulates contained within local separations resistor.
