ABSTRACT:
A cleaning device for removal of ink and other debris from the nozzle face of an ink jet printhead is disclosed. The cleaning device is located at a cleaning and priming station within the printer, and comprises a rotatable drum having at least one slot in which an absorbent material covered with a polymeric mesh material is manually inserted. When the printhead is located in the cleaning and priming station, the drum is rotated and the covered absorbent material wipes the nozzle face. In one embodiment, the printer is a carriage type with the cleaning station on one side of the printing region. The drum is surrounded by a housing with an opening so that the covered absorbent material is rotated therepast and into contact with the nozzle face of the printhead. The absorbent material is moistened to assist in cleaning the nozzle face in preventing ink removed from the nozzle face from drying on the mesh material. In a second embodiment, the drum has two slots, one for a dry cleaning member and one for a moistened cleaning member. Similar cleaning devices are disclosed for pagewidth printheads.
