Abstract
A replaceable inkjet printhead cartridge with ink and residue collectors thereon which use capillary channels to retain ink and residue wiped from the printhead orifice plate by a resilient wiper blade at a service station at one end of the path of travel of the printhead carriage. Some of the capillary channels are formed between spaced fins which engage the wiper blade. The fins have edges that terminate in a plane spaced from the front edge of the orifice plate in a direction to prevent the wiper blade from engaging a sharp side edge of the orifice plate. Capillary breaks are provided at desired locations to prevent removed ink and residue from migrating to undesired areas on the printhead such as electrical contact areas or pads. The printhead cartridge conveniently allows removal of dried ink and residue from the printer when replacing the cartridge.
