Printhead maintenance station having contact pad with sloping profile
Abstract:
A printhead maintenance station for maintaining a printhead in an operable condition. The maintenance station comprises an elastically deformable pad having a contact surface for sealing contact with nozzles in an ink ejection face of the printhead. The contact surface has a sloping profile. The maintenance station has a motor and cam arrangement for moving the pad substantially perpendicularly with respect to the ink ejection face. The pad moves from a first position in which the contact surface is sealingly contacted with the nozzles to a second position in which the contact surface is disengaged from the face. The movement and the sloping profile of the pad causes the contact surface to be peeled away from the face during disengagement.
