Abstract
A printhead maintenance cap includes a base and a wall portion. The wall portion is defined by a plurality of adjoining walls, and has a proximal end and a distal end, the plurality of adjoining walls defining an interior region. The proximal end is coupled to the base. A first lip extends from the distal end of the wall portion by a first extent in a direction non-orthogonal to the base, the first lip defining a first perimetrical sealing surface. A second lip extends from the distal end of the wall portion by a second extent, the second lip being spaced apart from the first lip, the second lip defining a second perimetrical sealing surface.
