Abstract:
1. A maintenance station apparatus for a printhead including a plurality of jetting modules disposed side by side in a row and inclined relative to a direction of print media motion, each of the plurality of jetting modules including a nozzle face, each nozzle face including a first nozzle array configured to eject a first liquid and a second nozzle array configured to eject a second liquid, the maintenance station apparatus comprising: a wiping unit including a first wiper, a second wiper, and a wiper moving mechanism, the first wiper being associated with the first nozzle array of each of the plurality of jetting modules and the second wiper being associated with the second nozzle array of each of the plurality of jetting modules, the first wiper being disposed on the wiper moving mechanism such that the first wiper contacts all of the nozzle faces at a first location on each of the nozzle faces between the first nozzle array and the second nozzle array of each of the plurality of jetting modules and moves across the first nozzle array of each of the plurality of jetting modules to a second location removed from the first nozzle array of each of the plurality of jetting modules, the second wiper being disposed on the wiper moving mechanism such that the second wiper contacts each nozzle face at a third location between the first nozzle array and the second nozzle array of each of the plurality of jetting modules and moves across the second nozzle array of each of the plurality of jetting module to a fourth location removed from the second nozzle array of each of the plurality of jetting modules; a capping unit including a plurality of cap pairs each corresponding to one of the plurality of jetting modules, one cap of each cap pair being associated with the first nozzle array of the corresponding jetting module, the other cap of the cap pair being associated with the second nozzle array of the corresponding jetting module, the capping unit being moveable between the first wiper and the second wiper to a first position in which each of the plurality of cap pairs is in contact with the first nozzle array and second nozzle array of the corresponding jetting module and a second position removed from contact with the first nozzle array and second nozzle array of the corresponding jetting module; and wherein the wiper moving mechanism includes a moveable frame to which the first wiper and the second wiper are affixed, and wherein the moveable frame includes an opening between the first wiper and the second wiper wherein the capping unit and the plurality of cap pairs are all moveable between the first wiper and the second wiper through the opening of the frame.
