Abstract
A lid for a print cartridge. The lid includes a barrier configured to seal the ink reservoir of the print cartridge and a stand-off spaced from the barrier. The stand-off is configured to engage ink-permeable foam. The lid may also include an alignment structure coupled with the stand-off and a capillary break adjacent the alignment structure. The capillary break is configured to impede the formation of capillary paths between the ink reservoir and the lid.
