Abstract: An apparatus has a first plate having a first array of holes, with a first plate alignment hole having a smaller size than the other holes in the array, a second plate having a second array of holes to be alignable to the first array of holes, a second plate alignment hole having a smaller size than the other holes in the array, and the first plate alignment hole and the second plate alignment hole having different positions. A method of aligning plates provides a first plate having a top and bottom and first array of holes including a first plate alignment hole having a size smaller than the other holes in the first array, places a second plate having a second array of holes on the top of the first plate such that the first array of holes and the second array of holes align, directs light at the bottom of the first plate, locates a profile of the first plate alignment hole in the second array of holes to verify alignment.

Abstract: A drip bib for use with a printhead of an imaging device includes a plate having an upper surface having an upper edge, an intermediate surface angled with respect to the upper surface, and a lower edge. The intermediate surface includes a plurality of fastener openings. The lower edge includes a drip point projecting from the lower edge with remaining portions of the lower edge being upturned and angled downwardly from at least one end of the lower edge toward the drip point. A plurality of protrusions protrudes from a back side of the upper surface. The protrusions in the plurality of protrusions are spaced from each other and proximate the upper edge.

Abstract: An inkjet finger manifold is provided that includes a longitudinal manifold chamber with an entrance at a first end adjacent to a first longitudinal side. A purge vent is located at a second end on a second longitudinal side opposite the first longitudinal side. A first ramp is located at the first end sloping away from the entrance toward the second longitudinal side. A second ramp is located near the second end and slopes from the second longitudinal side toward the second end and the first longitudinal side to alter the laminar flow of the ink through the longitudinal manifold.
