EPSON 774 BLACK INK BOTTLE ORGINAL

Product Description

EPSON 774 BLACK INK BOTTLE

The Epson 774 Black Ink Bottle (Official SKU: C13T774100 / T7741) is a genuine, high-capacity monochrome liquid refill bottle designed primarily for commercial and office-centric EcoTank / InkTank systems. Unlike standard 664 series color formulations, the 774 line consists of a specialized, high-density pigment-based ink formula. This chemical configuration ensures that text documents achieve sharp, sharp-edged black letter definitions that mirror laser-printer quality while remaining highly resistant to water, smudging, and highlighter fading.

Exhaustive List of Supported Printer Models [1]

The chemical viscosity of the 774 pigment formula and its nozzle configurations are restricted to specific workgroup monochrome models and high-end office-class EcoTank machines. [1, 2]

The complete, unrestricted list of compatible hardware models includes:

1. Epson M-Series Single-Function (Desktop Monochrome Printers) [1]

These dedicated black-and-white laser-alternative desktop systems rely on the 774 pigment bottle to manage heavy document printing:

• Epson EcoTank M105 (Wi-Fi Configured) [1, 2, 3]

2. Epson M-Series Multifunction (All-in-One Monochrome Peripherals)

These high-speed black-and-white office setups deploy the 774 platform to drive network printing, flatbed scanning, sheet-fed copying, and digital business faxing:

• Epson EcoTank M200

• Epson EcoTank M205 (Wi-Fi Configured) [1]

3. Epson L-Series Multifunction Office Peripherals (Color Hardware)

5. Epson Expression & WorkForce Series (Regional Multi-Fit Variations) [1]

In specific North American and European enterprise sales channels, the matching hardware frameworks and fluid components operate under alternative consumer series labels:

• Epson Expression ET-3600 EcoTank

• Epson Expression ET-4550 EcoTank

• Epson WorkForce ET-16500 EcoTank [, 2, 3]

Critical Refill Notice: Never Mix Pigment and Dye Inks

Because the 774 series is a pigment-based formula, it contains tiny solid color particles suspended in liquid. You must never pour this ink into an EcoTank printer designed exclusively for dye-based black inks (such as the L3110, L3210, or 664/003 systems). Mixing dye and pigment inks inside the same fluid lines creates a chemical reaction that thickens the liquid into a sludge, permanently clogging the micro-nozzles of your printer's permanent printhead
