Driving path is as follow.
Figure 3-42. Inksystem Mechanism Drive Path (1)
Figure 3-43. Inksystem Mechanism Drive Path (2)
The Clutch, Intermittent Gear 1, Intermittent Gear 2, and Wiper/cap-drive Cam
move linked to the rotation of Combination Gear C, but if the Wiper moves to
the wiping position, the Intermittent Gear 2 teeth surface separate, and the
Combination Gear C drive is disengaged. At these times, the Wiper, Cap,
Valve, and CR Lock Lever will not operate even if the Pump Motor is rotating.
If the Pump Motor rotates in the opposite direction, then the Intermittent Gear 2
and Combination Gear C will again mesh, operating each part.
This prevents mechanisms except the pump mechanism from driving while the
Pump Motor rotates continuously to drive the pump mechanism.
