1. A structure for use in an apparatus for ejecting a marking material, comprising;
a body having at least two adjacent channels therein;
a marking material reservoir communicatively connected to at least one of said two adjacent channels; and
a metering device comprising a marking material transport region interposed between and communicatively coupled to at least one of said channels and said marking material reservoir, the marking material transport region including at least three electrodes, the at least three electrodes to generate an electric field to move portions of said marking material from said reservoir into said at least one channel.
a three phase voltage source coupled to the three electrodes.
a substrate having a proximal end and a distal end;
a marking material reservoir communicatively connected with said proximal end;
a channel communicatively connected with said distal end;
at least three electrodes formed on said substrate, a first of said electrodes being located generally at the proximal end of said substrate such that an electric field generated by said first electrode extends at least part-way into said marking material reservoir and further such that marking material located in said marking material reservoir may be attracted to said first electrode, each of said other at least three electrodes being configured such that each may selectively generate an electric field to thereby transport marking material from one electrode to another in a direction from said marking material reservoir toward said channel.
a marking material reservoir;
a body having defined therein a channel and a port such that marking material may be introduced through said port into said channel;
a substrate extending between said marking material reservoir and said body;
a plurality of sets of electrodes, each set comprising in order a first, a second, and a third electrode, the sets of electrodes arranged on the substrate such that, for each adjacent set of electrodes, the third electrode from one set is adjacent the first electrode of an adjacent set, and further such that a first set of electrodes is adjacent the marking material reservoir such that a first electrode of the first set of electrodes to generate an electric field that extends at least part-way into said marking material reservoir, and still further such that a final set of electrodes is adjacent the body such that a third electrode of the final set of electrodes to generate an electric field that extends at least part-way into said channel;
whereby said plurality of sets of electrodes are selectively activatable to thereby selectively generate electric fields which transport marking material from the marking material reservoir through said port and into said channel.
a marking material reservoir,
a body having defined therein a plurality of channels, each channel having a port associated therewith such that marking material may be introduced through said port into said channel;
a plurality of marking material delivery regions, each region bounded by an opposing pair of lateral barriers, an opposing barrier, and said substrate;
each marking material delivery region having disposed therein sets of electrodes, each set comprising in order an initial electrode, at least one intermediate electrode, and a terminal electrode, the sets of electrodes arranged on the substrate such that, for each adjacent set of electrodes within a marking material delivery region, the terminal electrode from one set is adjacent the initial electrode of an adjacent set, and further such that a first set of electrodes in each marking material delivery region is adjacent the marking material reservoir such that an initial electrode of a first set of to generate an electric field that extends at least part-way into said marking material reservoir, and still further such that a final set of electrodes in each said marking material delivery region is adjacent the body to allow electric fields that originate from a terminal electrode of a second set to extend at least part-way into one of said channels;
whereby said plurality of sets of electrodes are selectively activatable to thereby selectively generate electric fields which transport marking material from the marking material reservoir through at least one of said ports and into at least one of said channels.
an initial electrode of each said set of electrodes is in electrical communication with each initial electrode of each of the other of said plurality of sets of electrodes, and further wherein a terminal electrode of each set of electrodes disposed within a first marking material delivery region is in electrical communication with each terminal electrode of each of the other of said plurality of sets of electrodes disposed within said first marking material delivery region but electrically isolated from the electrodes of those sets of electrodes disposed outside said first marking material delivery region;
such that the sets of electrodes in each marking material delivery region form a metering device, each said metering device being independently addressable such that each said metering device may individually control the introduction of marking material from one said marking material reservoir into at least one of said channels.
