a first gear rotatable in both clockwise and counterclockwise directions;
a second gear to engage with the first gear, the second gear being rotatable around the first gear;
a cleaning roller fixed to the second gear to wipe a nozzle surface of a print head; and
a link arm to connect the first gear and the second gear,
wherein when the first gear is rotated, the second gear and the cleaning roller revolve in an upward direction around the
first gear by a frictional force between the first gear and the link arm until the cleaning roller contacts the nozzle surface,
and when the cleaning roller contacts the nozzle surface, the second gear and the cleaning roller rotate around an axis of
the second gear by a rotational force of the first gear to wipe the nozzle surface.
