Drive Path

The wiper mechanism, carriage lock mechanism, pump mechanism, and ink system mechanism is driven by the PF Motor's drive force. The drive path is as follows.

Wiper Mechanism/Carriage Lock Mechanism

The PF Motor's drive force is transmitted from the IS Driven Gear on the end of the PF Roller to the IS Spur Gear/IS Compound Gear/IS Clutch Gear/CR Lock Gear/CR Lock Cam via the ES Gear, and drives the wiper mechanism and the carriage lock mechanism.
The transmission of the PF Motor's drive force to the wiper mechanism and carriage lock mechanism is controlled by the cap mechanism and the IS Clutch Gear.

Drive path of the wiper mechanism and carriage lock mechanism (Cap Unit side view  )

Since the protrusion on the Cap Slider*1 is engaged with the hole on the Intermittent Gear normally, the Intermittent Gear is fixed and the PF Motor's drive force is not transmitted to the wiper mechanism or carriage lock mechanism.
If the position of the Cap Slider is changed for capping or the like, the protrusion on the Cap Slider is disengaged from the hole on the Intermittent Gear. Therefore, the Intermittent Gear rotates together with the IS Clutch Gear. In this state, the PF Motor's drive force is transmitted up to the wiper mechanism and carriage lock mechanism.

*1: The operation of the Cap Slider is carried out by the cap mechanism.  For the details, see Capping Mechanism.

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.
