Abstract: An inkjet printer includes a printhead; a carriage for moving the printhead back and forth in a carriage scan direction across the printing region; an output roller that is downstream of the printing region for moving recording medium away from the printing region, the output roller including a shaft; a pump that is coaxially disposed around the shaft of the output roller; and a restraining lever that disconnects the pump from power when the carriage is not in contact with the restraining lever.

Abstract: A device having a mechanical safety interlock is disclosed. The device has at least one moveable part contained in a housing. The moveable part is accessible through an opening in the housing. The device includes a cover for covering the opening. The mechanical safety interlock includes an actuator attached to the cover and a mechanical driver supported in the housing adjacent the moveable part. The driver is biased away from the moveable part to a disengaged position to interrupt transmission of mechanical movement from the driver to the moveable part. When the cover is brought to cover the opening, the actuator engages the driver to bring the driver to an engaged position to allow the moveable part to tap mechanical movement of the driver to thereby be driven.
