Epson WF-C579, WF-C529 Inksystem mechanism
Overview
The inksystem mechanism of this product is composed of the Inksystem Assy, and Maintenance Box.
The ink sucked by the Cap mechanism and Pump mechanism from the Printhead is drained via the Waste Ink Tube and into the Waste Ink Pad in the Maintenance Box.
The amount of waste ink is controlled by the counter in the firmware taking the amount of evaporation into account so as not to let the ink leak out of the printer because the waste ink exceeds the limit of the storage capacity.
Further, this product uses a mechanism by which the user him/herself can replace the Maintenance Box.
Operating principles
The ink system mechanism of this product employs the direct acting type (*) and consists of the carriage lock mechanism, wiper mechanism, capping mechanism, pump mechanism, and venting valve (valve mechanism).
(*) There are two types of the capping: direct acting type and sliding type. In the direct acting type, the cap moves up and down independently of the carriage and caps the printhead. In the sliding type, the printhead is capped (the cap is moved up) when the carriage pushes the cap slider.
All the mechanisms are driven by the pump motor. The drive force of the pump motor is transmitted to each mechanism via transmission parts, such as the pump-drive compound gear, clutch gear, intermittent gear, cam, and drive lever.
Additionally, this product utilize a maintenance box (waste ink pad) that retains waste ink from the cap, with which users can replace ink themselves.

Epson WF-C579, WF-C529 Inksystem drive sequence
The ink system mechanism is driven by the Pump Motor and driving path is as follow.
A – Combination Gear A | G – Intermittent Gear 1
B – Combination Gear B | H – Intermittent Gear 2
C – Spur Gear | I – Wiper/cap-drive Cam
D – Pump Drive Combination Gear | J – Wiper Gear 1
E – Combination Gear C | K – Wiper Gear 2
F – Clutch | L – Wiper Gear 3
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.
