ABSTRACT:
A printer maintenance apparatus, includes: a mounting base movable forward and backward between a maintenance position and a retraction position; a wiping mechanism mounted on the mounting base and including a wiper base and a wiper; and a capping mechanism mounted on the mounting base including a cap base and a cap. The cap base moves toward the nozzle surface to move the cap to cover the nozzle surface when the mounting base is at the maintenance position. The cap base moves retractably from the nozzle surface when the mounting base moves from the maintenance position. The wiper base moves toward the nozzle surface to bring the wiper into contact with the nozzle surface when the mounting base is at the maintenance position. The wiper base keeps the wiper in contact with the nozzle surface while the mounting base moves backward from the maintenance position.
