Abstract

A maintenance facility for an inkjet printer that has a printhead with an array of nozzles defined in a nozzle face and media feed assembly for moving sheets of print media past the printhead in a media feed direction. The printhead maintenance facility has a wiper member having a contact surface for wiping the nozzle face and a maintenance drive for moving the wiper member over the printhead in a direction parallel to the media feed direction. The contact surface has a nonlinear configuration such that during a wiping operation the contact surface will have two sections simultaneously in contact with the nozzle face.
