Can You Refill Epson ST-2000 Ink Bottles with BCH Technologies Refill Ink?

Question:
I have bottles of BCH refill ink for my Epson ST-2000 printer. I also have a set of Epson OEM bottles that came with the printer. Can I refill the Epson bottles with BCH ink so I can keep using their special fill-port design?

Answer:

Now, to answer your question: yes, in most cases, you can safely refill your Epson EcoTank or Supertank bottles (including those for the ST-2000) with BCH Technologies refill ink, provided you take a few precautions.

Understanding Epson's Bottle Design

Epson's EcoTank and Supertank ink bottles are cleverly engineered with a keyed nozzle design. Each bottle's tip is shaped to fit only the corresponding color port on your printer. This prevents accidental cross-color refills-for example, inserting cyan into the black tank-and ensures a secure, leak-free transfer.

Fortunately, the OEM Epson bottles are mechanically refillable. You can carefully remove the nozzle cap assembly (usually a twist-off or snap-on mechanism) to pour in new ink. Once refilled, the bottles will continue to work with the printer's original fill ports, maintaining that convenient spill-free refill system Epson is known for.

Steps for Refilling Epson OEM Bottles with BCH Ink

1. Empty and Clean the Bottle First:
   Before adding BCH ink, rinse your Epson bottle thoroughly with warm water to remove any residual ink. This step prevents contamination or color distortion. After rinsing, let the bottle dry completely-any leftover water can dilute the ink and alter print color intensity.

2. Use Matching Colors Only:
   Always refill each OEM bottle with the same color it originally contained (e.g., cyan with cyan). Even minor mixing between brands or color lines can cause foaming, pigment separation, or uneven flow that might clog your printhead over time.

3. Refill Carefully:
   When pouring ink into the bottle, use a funnel or syringe to minimize spills. Avoid overfilling-leave some air space at the top so the pressure system in the bottle can function correctly when connected to the printer.

4. Check the Rubber Gasket:
   Inside the bottle's nozzle, there's a small rubber gasket or seal that prevents leaks during refilling. If this gasket becomes loose or worn, it may cause dripping or incomplete transfer. If needed, you can bypass the nozzle and refill your printer directly with a syringe.

5. Avoid Mixing Different Ink Brands in One Bottle:
   If your Epson bottle still contains some OEM ink, do not top it off with BCH ink until it's completely empty and cleaned. Different ink chemistries-especially between OEM dye inks and BCH pigment or hybrid formulas-can react and form sediment or gel-like residue.

Why BCH Refill Ink Works with Epson ST-2000 Printers

BCH Technologies refill inks are engineered to match the viscosity, surface tension, and color formulation required by Epson's ST-series printheads. They produce vibrant, consistent results while maintaining smooth ink flow. You'll enjoy the same quality output as with Epson's original inks-without clogs or over-saturation-while saving significantly on printing costs.

By refilling your OEM Epson bottles with BCH ink, you get the best of both worlds: the ease of Epson's no-mess bottle design and the affordability and performance of BCH refill ink.
