Printhead nozzle maintenance

摘要

A printhead maintenance device includes a maintenance housing including a set of maintenance nozzles, an air controlling member, and a waste collector. The maintenance housing moves to selectively position the set of maintenance nozzles opposite a printhead including a nozzle surface having a plurality of nozzles to eject fluid. The set of maintenance nozzles provide fluid onto the nozzle surface of the printhead to remove residue therefrom. The air controlling member forms air flow paths to at least one of direct the fluid provided by the maintenance nozzles at an angle to the nozzle surface and direct the residue maintenance nozzles to the waste collector.

1. A printhead maintenance device comprising:
a maintenance housing including a set of maintenance nozzles, an air controlling member, and a waste collector, the maintenance housing to move to selectively position the set of maintenance nozzles opposite a printhead including a nozzle surface having a plurality of nozzles to eject fluid;
the set of maintenance nozzles to provide fluid onto the nozzle surface of the printhead to remove residue therefrom;the air controlling member to form air flow paths to deflect a direction of fluid as provided by the maintenance nozzles such that the fluid is directed at a new angle onto the nozzle surface and direct the residue from the nozzle surface to the waste collector; andthe waste collector to collect the residue removed from the nozzle surface; wherein the maintenance housing further comprises: a first slot in which the first air flow path passes through to direct the fluid from the set of maintenance nozzles onto a respective nozzle surface; and a second slot in which the second air flow path passes through to receive the residue; wherein the set of maintenance nozzles are linearly arranged parallel to and between longitudinal axes of the first and second slots.
