Abstract
A modular printhead assembly includes an elongate substrate member that defines a plurality of holes. An ink conduit is mounted longitudinally on one side of the substrate member and defines a plurality of ink holes to be in fluid communication with the ink holes defined by the elongate substrate member. A plurality of printhead module assemblies is mounted along an opposite side of the substrate member. Each module assembly includes an ink feed structure in fluid communication with the ink holes defined by the elongate substrate member and a printhead integrated circuit in fluid communication with the ink feed structure. A bus bar assembly is arranged on the substrate member for providing the printhead integrated circuits with power.

A modular printhead assembly comprising
- a channel that defines a plurality of holes;
- an ink conduit mounted longitudinally on one side of the channel and defining a plurality of holes to be in fluid communication with the ink holes defined by the channel;
- a plurality of printhead module assemblies mounted along an opposite side of the channel, each module assembly including an ink feed structure in fluid communication with the ink holes defined by the channel and a printhead integrated circuit in fluid communication with the ink feed structure;
- and
- a bus bar assembly arranged on the substrate member for providing the printhead integrated circuits with power;
- wherein,
- the ink conduit is an extruded flexible hose that defines parallel channels that extend the length of the channel, one end of the hose being capped and the other end being connectable to ink containers.
