An improved ink-jet printhead cap (10) is described. In its preferred embodiment, the cap (10) has a sealing lip (20), which extends peripherally around the generally planar expanse (18) of the cap (10), the lip (20) being suspended by a horizontal, resiliently deflectable, elastomer span (18) that is supported on either end by vertical supports (14,16) that define a channel (13) dimensioned to receive partway therein the annular boss of a cap mount (30) mounted on a sled (28). In cross section, the lip (20) is centered above the channel (13), protrudes upwardly from an upper surface of the horizontal span (18), and tapers inwardly and upwardly substantially to a point, thus providing a conformable, focal impact point for sealingly engaging a printhead (34,36,38). The amount of force required to deflect the lip (20) may be controlled by varying the thickness of the horizontal span (18) and the distance between the vertical supports (14,16). <IMAGE> |
