Cap Mechanism
The direct acting type is employed in the capping mechanism, where the Cap is
moved up and down by the Pump Motor and the printhead is capped at the
suction for cleaning.
Intermittent Gear 2 rotates on drive power from the Pump Motor, and the cam
surface on the Intermittent Gear 2 pushes the Cap, moving it forward. At this time,
the cap tab contacts the printhead surface, guiding the Printhead on the Cap.
Next, the Wiper/cap-drive Cam moves the Cap Drive Lever, raising the Cap,
capping the Printhead.
