ABSTRACT:
A printhead maintenance station for maintaining a printhead in an operable condition is provided. The maintenance station comprises an elastically deformable pad having a contact surface for sealing engagement with an ink ejection face of the printhead. The contact surface is sloped with respect to the face. The maintenance station further comprises an engagement mechanism for reciprocally moving the pad between a first position in which the contact surface is sealingly engaged with the face, and a second position in which the contact surface is disengaged from the face. The engagement mechanism moves the pad substantially perpendicularly with respect to the face.
