Abstract
An inkjet printhead with an integrated sealing and wiping function is disclosed. A printhead body is provided with at least one nozzle opening. A shutter member movably engages the printhead, and an actuator moves the shutter member between an open position and a closed position. When in the open position, the shutter member exposes the nozzle opening, allowing the printhead to deposit ink onto a printing medium such as paper. When the printhead is not printing or is in a maintenance mode, the actuator moves the shutter member to the closed position. During the movement, the shutter member performs a wiping function on the nozzle opening. Once the shutter member has been moved to the closed position, it acts to cap, or seal, the nozzle opening from the outside environment.
