Abstract
Inkjet printheads and actuator chips, such as an inkjet printhead actuator chip having a substrate, ink vias formed in the substrate, and columnar arrays of actuators in operational communication with the ink vias. At least one of the ink vias has at least one of a different length, width and a via to via pitch than another one of the ink vias. Imaging devices for use with the printheads are also disclosed.
Claims16
An inkjet printhead actuator chip, comprising:
- a substrate;
- ink vias formed in the substrate, at least one of said ink vias having at least one of a different length, width and a via to via pitch than another one of the ink vias;
- columnar arrays of actuators in operational communication with the ink vias.
An actuator chip for an inkjet printhead, comprising:
- a substrate;
- parallel columnar arrays of actuators adjacent the substrate;
- ink vias for supplying the actuators with ink, said ink vias being formed in said substrate, at least one of the ink vias having at least one of a length, a width, and a via to via pitch that is different from that of another one of the ink vias;
- and
- a column of input terminals being substantially perpendicular to said arrays.
An inkjet printhead comprising a substantially rectangular actuator chip having at least four substantially parallel ink vias, two of said at least four substantially parallel ink vias having substantially the same lengths and widths, and at least one of the other vias having a length and a width that is different from the lengths and the widths of the three vias.
An inkjet printhead, comprising a substantially rectangular actuator chip having at least five substantially parallel ink vias, four of said at least five substantially parallel ink vias having substantially the same lengths and widths, and at least one of the other vias having a length and a width that is different from the lengths and the widths of the four vias.
