Enlite 300ml 4-Color CISS Bulk Ink Supply System (Without Chip) for Epson WorkForce Pro WF-C5290 WF-C5790 WF-C5390 WF-C5890 PX-M884 PX-M885 PX-M887

Constant-Pressure Dual-Chamber Balance

Utilizes a precision hydraulic air-balance chamber that equalizes ink pressure as levels drop. Prevents hydrostatic over-pressure siphoning (which causes printhead dripping) and eliminates air locks during continuous high-speed double-sided printing.

Heavy-Duty PP & Anti-Kink Silicone Tubing

Molded from high-density virgin polypropylene with excellent solvent and chemical resistance. Paired with 4-channel anti-kink silicone tubing that withstands carriage movements, resists hardening or cracking, and ensures laminar ink flow.

Maximum Commercial ROI & Flexible Sourcing

Transitioning to Enlite’s 300ml CISS allows commercial print shops and copy centers to utilize 1-liter bulk bottled ink. Supplying the hardware without chips gives distributors and service providers maximum flexibility to pair their own region-specific chips or solutions.

Direct Factory Sourcing • 64,000㎡ Modern Production Base

Q1: How does this CISS tank connect to Epson WorkForce Pro WF-C5290 / WF-C5390 series printers?

This 300ml modular CISS system features dedicated 4-line silicone tubing that routes neatly into the printer’s front cartridge bay using included routing clips. It connects directly to refillable cartridge bodies or dampers, providing an uninterrupted external gravity-balanced ink reservoir.

Q2: Does this CISS system include chips, and how is chip recognition handled?

No, this CISS unit is supplied as a hardware kit without chips. Because Epson WorkForce Pro models require valid chip recognition across different regions, customers and technicians must provide their own compatible chips (such as one-time chips or auto-reset chips) or transfer chips according to their local printer specifications.

Q3: What types of ink are recommended for this 300ml CISS reservoir?

The chemical-resistant polypropylene body is fully compatible with waterproof pigment inks, high-vibrancy dye inks, and sublimation inks. Enlite also formulates and supplies matched 1000ml bulk bottled inks engineered specifically for Epson PrecisionCore printheads.

Q4: What is the packaging specification, Minimum Order Quantity (MOQ), and shipping lead time?

Standard commercial orders ship in protective bulk packs or neutral white boxes. Standard B2B wholesale MOQ is 20 sets; sample evaluation sets are available upon request. Regular inventory ships within 24–48 hours from our Zhuhai factory.
