Epson EcoTank Ink Bottles – 101 series

Zero-Mess Refills.

The Epson 101 EcoTank Ink Bottle Series delivers premium-quality, high-efficiency printing tailored specifically for modern EcoTank models, including the L4150, L4160, L6160, L6170, and L6190 printers. This series features a hybrid formulation pairing a pigment black ink (127.0 ml) for laser-sharp, water-resistant, smudge-proof business typography with dye-based cyan, magenta, and yellow color inks (70.0 ml each) designed to render rich photos and graphics with smooth tonal gradations.

Equipped with next-generation key-lock auto-stop bottle nozzles, each color fits exclusively into its designated tank port to ensure direct, effortless refills without manual squeezing, back-pressure leaks, or color cross-contamination. Manufactured under strict ISO cleanroom parameters, the genuine 101 series protects delicate Micro Piezo printhead nozzles while providing exceptional yield capacity—up to 7,500 crisp black pages and 6,000 vibrant color pages—to keep everyday operational costs remarkably low.

Key Features

Key-Lock Auto-Stop Nozzles

Each color bottle features a unique keyed nozzle design that fits strictly into its corresponding tank opening. The internal valve opens automatically during docking and seals immediately upon removal to stop spills and prevent color cross-contamination.

Hybrid Ink Formulation

Combines high-density black pigment ink with vibrant dye-based cyan, magenta, and yellow color inks. The pigment black delivers crisp, water-resistant text documents, while dye colors render smooth photo transitions and rich graphics across various paper stocks.

Exceptional Page Yield

High-capacity bottles supply long-lasting fluid reserves capable of printing up to 7,500 black pages and 6,000 color pages per complete set. High page output dramatically lowers overall cost per page and reduces refill frequency for busy households and offices.

Micro Piezo Printhead Protection

Formulated under cleanroom conditions with balanced fluid viscosity to prevent sediment accumulation and nozzle clogging. Genuine ink composition preserves thermal stability across print passes to maintain consistent print head lifespan and hardware performance.

Mess-Free Pressure Equalization

Integrated bottle venting channels equalize internal atmospheric pressure during refilling to allow steady fluid transfer without manual squeezing. Liquid stops flowing automatically when the internal reservoir reaches full capacity to eliminate accidental overfills.
