Abstract

An improved ink-jet printhead cap is described. In its preferred embodiment, the cap has a sealing lip, which extends peripherally around the generally planar expanse of the cap, the lip being suspended by a horizontal, resiliently deflectable, elastomer span that is supported on either end by vertical supports that define a channel dimensioned to receive partway therein the annular boss of a cap mount mounted on a sled. In cross section, the lip is centered above the channel, protrudes upwardly from an upper surface of the horizontal span, and tapers inwardly and upwardly substantially to a point, thus providing a conformable, focal impact point for sealingly engaging a printhead. The amount of force required to deflect the lip may be controlled by varying the thickness of the horizontal span and the distance between vertical supports.
