A coupling for distributing fluid to a printhead, the coupling having a housing, a port plate movably mounted on the housing by a shaft, the port plate having a plurality of ports for receiving respective fluid spouts of the printhead, a seal member mounted on the housing between the housing and the port plate, the seal member having a plurality of seals which align with respective ones of the ports of the port plate and a compression spring mounted on the shaft by a washer so as to be compressed between the washer and the port plate.

Printhead coupling for fluid distribution

A system for coupling a media width printhead to a fluid supply is provided having a printhead having a fluid inlet coupling at one longitudinal end of the media width and a fluid outlet coupling at the other longitudinal end of the media width, an inlet supply coupling having fluid ports defined in a port plate for engagement with fluid ports of the inlet coupling, an outlet supply coupling having fluid ports defined in a port plate for engagement with fluid ports of the outlet coupling, and a coupling drive mechanism connected to the port plates of the supply couplings via pre-compressed compression springs. The coupling drive mechanism is operational to move the port plates relative to the printhead so as to drive the ports of the supply couplings into engagement with the respective ports of the printhead couplings.

System for coupling fluid supply to printhead

A coupling assembly for distributing fluid to a printhead, the coupling assembly having a housing, a seal member received in a recess of the housing, a port plate movably mounted on the housing by a washer which is press-on mounted to a shaft through the port plate and housing, and a tube retainer mounted within a groove of the housing for retaining fluid distribution tubes, the retainer having a plurality of holes aligned with respective ones of a plurality of ports in the port plate and a plurality of seals of the seal member for fluidically connecting the retained fluid distribution tubes with respective fluid spouts of the printhead, wherein mounting of each of the seal member, port plate and retainer to the housing is achieved in a non-fastened manner.

Simple printhead coupling for fluid distribution

A coupling assembly for distributing fluid to a printhead, the coupling assembly having a housing, a port plate movably mounted to a shaft which passes through the port plate and housing, a compression spring mounted on the shaft by a washer so as to be compressed between the washer and the port plate and an arm pivotally connected to the shaft at one of its longitudinal ends and pivotally connected to a coupling drive mechanism at its other longitudinal end.
