Liquid supply or reservoir therefore having multiple compartments, each compartment to hold a distinct liquid, comprising multiple liquid outlets, each fluidically connected to one of the compartments, multiple clearance cut outs disposed at a pitch equal to a pitch of the compartments to accommodate protrusions of a dispenser, and at least one latch protruding outwards from a supply wall.

Replaceable liquid supply having cut outs and latch

A flexible circuit includes a sprocket opening and electrically conductive lines connected to a print head.

Flexible circuit

An inkjet printing device printhead assembly includes a housing. The housing has a surface. A well is defined within the surface of the housing and is adapted to disposal of a printhead die therewithin. The surface of the housing has one or more grooves. The grooves have ends. Some of the ends are adjacent to the wall. The grooves externally expose the printhead die.

Printhead assembly having grooves externally exposing printhead die

An assembly includes a flexible electrical circuit and a housing having a support surface configured to receive the flexible electrical circuit. A plurality of three-dimensional impressions are symmetrically positioned across the support surface and extending below the support surface. The plurality of three-dimensional impressions are deformed when the flexible circuit is joined to the support surface.

Print cartridge

A method of laser machining a fluid path is provided. The method comprises directing a first laser toward a first surface, directing a second laser toward a second surface of the substrate, and directing a third laser toward the second surface along at least a portion of an edge of an area that defines a portion of the fluid path on the second surface.
