An assembly according to one example embodiment includes an electrically conductive fastener that includes a head and a shank. The shank extends from an undersurface of the head along a longitudinal axis of the fastener to a distal end of the fastener. A fastening hole is formed by an electrically nonconductive material. At least a portion of the shank of the fastener is installed in the fastening hole. An electrically conductive component is held between the undersurface of the head of the fastener and a surface surrounding an entrance to the fastening hole. An electrically conductive flange extends from the component and contacts an outer portion of the head of the fastener such that an electrical path is formed between the fastener and the component.

A nozzle plate for bonding to a chip for configuring a printhead of a printing device is disclosed. The chip comprises a plurality of energizing elements. The nozzle plate comprises a substrate layer, an adhesive layer and a plurality of nozzle holes perforated in the substrate layer and the adhesive layer. The each nozzle hole is capable of being associated with an energizing element of the plurality of energizing elements. The each nozzle hole comprises an asymmetric flow-feature configured by ablating at least a portion of a wall of the each nozzle hole prior to bonding the nozzle plate to the chip. The nozzle plate provides a substantially symmetrical flow-feature for the each nozzle hole on bonding to the chip.

A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.

A printhead body for mounting a micro-fluid ejection chip includes a floor having an interior side and an exterior side, the exterior side being configured for mounting at least one micro-fluid ejection chip. A plurality of body vias extends through the floor from the interior side to the exterior side. The plurality of body vias is positioned to supply ink to each micro-fluid ejection chip. A plurality of ink flow channels is formed over the interior side of the floor. The plurality of ink flow channels include at least a first ink flow channel vertically overlapping a separate and independent second ink flow channel. Each individual ink flow channel of the plurality of ink flow channels is in fluid communication with at least one body via of the plurality of body vias.
