Abstract
A component for a drop on demand printhead having three groups of actuators arranged on a surface forming a central group and two end groups. The electrical connections for the central group are split, one portion extending towards one edge of the surface in one direction, and the remaining portion extending towards an edge in a different direction. Such components can be butted together to form an array of such components providing improved actuator density along the module, and facilitating improved electrical connection.
Claims17
A component for a drop on demand printhead comprising
- a mounting surface;
- three groups of actuators arranged on said surface, each group adapted to selectively eject fluid from a corresponding group of nozzles in response to an electric actuation signal, said groups spaced apart in a lateral direction thereby defining a central group and two end groups;
- and,
- electrical connections extending from said groups across said mounting surface, said connections allowing electric actuation signals to be applied to said actuators;
- wherein a first fraction of said electrical connections for said central group extend laterally away from said central group towards a first side of said surface, and wherein the remaining fraction of said electrical connections for said central group extend laterally away from said group towards a second side of said surface.
A modular array of printhead components arranged along a module axis, each printhead component comprising:
- a mounting surface;
- a central group of actuators arranged on said surface, and two end groups of actuators arranged on said surface, spaced apart from said central group perpendicular to said module axis;
- each group of actuators adapted to selectively eject fluid from a corresponding group of nozzles in response to an electric actuation signal;
- and
- electrical connections extending from said groups across said mounting surface, said connections allowing electric actuation signals to be applied to said actuators;
- wherein a first fraction of said electrical connections for said central group extend away from said central group on a first side of said module axis, and wherein the remaining fraction of said electrical connections for said central group extend away from said group on the second side of said module axis.
