Overview

The Epson 522 EcoTank Color Combo Pack (T522520-S) is a genuine OEM ink refill set for Epson's EcoTank printer line — the open-reservoir printing architecture designed to eliminate recurring cartridge costs. This set contains three ultra-high-capacity bottles in cyan, magenta, and yellow, rated for approximately 7,500 pages of combined color output. The EcoFit bottle design is the key usability differentiator: each nozzle is physically keyed to prevent installation in the wrong tank port, addressing the contamination risk that makes open-tank ink systems error-prone without this feature.

This ink is the correct consumable for EcoTank users running high print volumes in home offices, small businesses, or education environments where the cost-per-page math of EcoTank ownership pays off. Compatible models include the ET-2400, ET-2720, ET-2800, ET-2803, ET-2840, ET-4700, ET-4800, and ET-4810. Because Epson's EcoTank printers are calibrated to their own ink formulation — including the viscosity and pigment suspension that governs head cleaning cycles — using genuine Epson ink is the straightforward way to maintain print quality and head longevity over years of use. Note that black ink is sold separately; this set covers CMY only.

Pros & Cons

👍 Pros

  • 7,500 color page yield per set delivers an extremely low cost per page compared to traditional ink cartridges
  • 7,500-page color yield per bottle set delivers a dramatically lower cost-per-page compared to traditional cartridge-based printing
  • EcoFit keyed nozzles physically prevent wrong-color installation, eliminating a common refill error that ruins tank ink in open systems
  • EcoFit keyed bottle design prevents cross-color filling errors and virtually eliminates spill risk during refills
  • Genuine Epson ink formulation maintains consistent color accuracy and protects print head longevity across thousands of pages
  • Genuine Epson formulation ensures color accuracy and head cleaning cycles work as the printer was calibrated to expect
  • Ultra-high-capacity bottles reduce refill frequency significantly on high-volume print environments
  • Compatible with eight EcoTank printer models, covering a wide range of home and small office setups
  • Compatible across eight EcoTank models, making it a consistent consumable for multi-printer office setups using the ET line

👎 Cons

  • Black ink is not included — must be purchased separately, which adds cost and a second ordering step for full replenishment
  • Black ink is not included — the combo pack covers only CMY, requiring a separate purchase for a complete refill
  • Compatibility is limited to eight specific EcoTank models; incompatible printers cannot use this ink
  • Only compatible with EcoFit-equipped EcoTank printers, offering zero compatibility with Epson's cartridge-based models
  • Higher upfront purchase price than a single set of traditional cartridges, despite the dramatically lower per-page cost
  • Refilling EcoTank reservoirs manually still requires care to avoid spills, despite the keyed bottle design
  • High upfront bottle cost versus per-cartridge pricing may not be economical for very low-volume users
  • Ink bottles have no resealable cap after opening, so partially used bottles should be used promptly to avoid potential drying at the nozzle tip
  • Once the tank is filled with Epson ink, switching to third-party ink risks compatibility and warranty issues

Frequently Asked Questions

This set works with the Epson ET-2400, ET-2720, ET-2800, ET-2803, ET-2840, ET-4700, ET-4800, and ET-4810. These are all EcoTank models with the EcoFit keyed bottle system — standard Epson cartridge-based printers cannot use these bottles.
Epson rates the 522 color combo pack (cyan, magenta, yellow) at approximately 7,500 pages combined yield. Actual page yield will vary based on print coverage percentage, print mode settings, and document content.
No. The 522 ink is specifically designed for a defined set of Epson EcoTank printers: ET-2400, ET-2720, ET-2800, ET-2803, ET-2840, ET-4700, ET-4800, and ET-4810. Using 522 ink in an incompatible EcoTank model may result in errors or damage.
The T522520-S is a color multi-pack containing cyan, magenta, and yellow ink bottles. Black ink (T522120) is sold separately and is not included.
Each bottle has a uniquely keyed nozzle that only fits the correct color reservoir on compatible EcoTank printers. The nozzle locks into place and controls ink flow automatically, so the bottle cannot be inserted into the wrong tank and ink stops dispensing when the tank is full.
Each 522 bottle has a unique nozzle shape keyed to match only the correct tank port on compatible EcoTank printers. This prevents accidental installation of the wrong color into the wrong tank — a common cause of ink contamination in open-tank refill systems.
No. The T522520-S is a color combo pack containing cyan, magenta, and yellow only. Black ink (522 black bottle) is sold separately.
At 7,500 color pages per bottle set, the EcoTank system delivers roughly 10–15x the yield of standard ink cartridges at a fraction of the per-page cost. This is where the up to 80% savings claim comes from — it is a cost-per-page comparison, not a purchase-price comparison.
Genuine Epson 522 ink is formulated to match the print head specifications of EcoTank printers, ensuring consistent color accuracy and preventing clogging. Third-party inks may save upfront cost but can introduce color inconsistency and risk print head damage that voids warranty coverage.
Third-party inks may void Epson's warranty and can cause clogging or color inaccuracy in EcoTank systems calibrated for Epson's ink formulation. Genuine Epson ink ensures the color profiles and head maintenance cycles function as designed.
