CR Lock Mechanism
The tension of the compression spring at the bottom of the CR Lock moves up
the CR Lock. When the CR Lock Drive Lever pushes the CR Lock downward,
the CR Lock is released.
Since the CR Lock Drive Lever moves up and down together with the Cap
Drive Lever, the CR Lock also operates together with the movement of the
Cap. This means that the printhead nozzle surface is always capped when the
CR Lock is set.

Wiper Mechanism
The rotation of the Wiper/cap-drive Cam drives the wiper mechanism. After
