Pump Mechanism
The PF Motor's drive force is transmitted from the IS Driven Gear on the end of the PF Roller to the ES Compound Gear/Pump Compound Gear/Pump Driven Gear via the ES Gear, and drives the pump mechanism.
The PF Motor's drive force is always transmitted to the pump mechanism
Capping Mechanism
When the CR Unit moves to the home position, the Cap Slider is pushed up by the CR Unit and caps the Print Head. When the CR Unit moves away from the home position, the Cap Slider falls and the capping is released (vented to atmosphere). The ink system mechanism of WF-C8690/C8690a/WF-C8610/WF-C8190/C8190a does not have any venting valves, but this Cap Slider's operation in conjunction with the CR Unit's movement realizes the performance of the traditional venting valves.
