AI Verdict

A 3.84-ounce black ink bottle designed for specific Epson EcoTank printers (ET-2720, ET-4700) that offers thousands of pages and low-cost refills.

Strong Fit

This black ink bottle is a strong fit for its intended use with compatible Epson EcoTank printers like the ET-2720 and ET-4700. Its high yield and EcoFit design directly address the core value proposition of the EcoTank system: low-cost, high-volume, and easy refilling, making it ideal for frequent document printing.

If you need professional photo quality, look for EcoTank models specifically designed for photography, often featuring additional dye-based inks, rather than relying on standard EcoTank black ink.

Dimension Scores

Comfort & Support8/10

The EcoFit bottle design is uniquely keyed for easy, spill-free filling, making the process straightforward for most users.

Adjustability4/10

The ink bottle's keyed design restricts its use to specific compatible EcoTank models (ET-2720, ET-4700), limiting its adaptability across the broader EcoTank line.

Build Quality7/10

The genuine Epson ink bottle is designed to prevent leaks during refilling and maintain ink integrity, though external packaging can sometimes be damaged during shipping.

Aesthetics5/10

The bottle has a functional design focused on spill-free refilling rather than visual appeal, which is typical for an ink consumable.

Best For

  • Owners of Epson EcoTank ET-2720 or ET-4700 printers seeking black ink refills.
  • Individuals or small businesses with high-volume black and white printing needs.
  • Users prioritizing long-term cost savings on printer consumables.

Not Recommended For

  • Users of non-compatible Epson EcoTank models or other printer brands.
  • Photographers requiring professional-grade photo prints from their EcoTank printer.
  • Those who frequently switch between genuine and third-party inks, risking print head issues.

Watch Out For

  • Ink bottles sometimes don't drain into the printer's reservoir, even when correctly inserted, requiring troubleshooting or multiple attempts.
  • The outer packaging has arrived crushed for some buyers, though the ink bottle itself was intact.
  • Using non-genuine ink can lead to issues like faster fading, clogged print heads, or inaccurate color hues, despite potential cost savings.
  • The ink bottles are not always perfectly sized to fill the tanks completely, potentially leaving residual ink in the bottle or requiring topping off.

What Buyers Say

Users consistently highlight the exceptional longevity of this black ink, with many reporting that a single bottle lasts for a year or more, significantly reducing the hassle and cost of frequent ink replacements. The EcoFit bottle design receives praise for making the refilling process clean and simple, largely eliminating the mess associated with older ink systems. However, a recurring complaint involves the ink sometimes not draining into the printer reservoir, causing frustration and requiring users to troubleshoot the issue.

“Dude, this ink seriously lasts forever, I haven't bought black ink in like a year and a half for my ET-2720, it's crazy how much money I'm saving but sometimes getting it to actually drain into the printer is a pain.”

Common Praise

  • Ink lasts for an incredibly long time, some users reporting 1.5 to 2 years of use before needing a refill.
  • Refilling the ink tank is easy and mess-free due to the keyed EcoFit bottle design.
  • Produces sharp text and images for everyday printing needs.
  • Offers substantial cost savings compared to buying traditional ink cartridges.
  • The convenience of not having to change cartridges frequently is a major plus.

Common Complaints

  • The ink bottle sometimes doesn't drain into the printer's reservoir, even when properly seated, leading to difficulties.
  • Some shipments arrive with crushed outer packaging, although the ink bottle itself is usually undamaged.
  • Lower-end EcoTank printers using this ink might not meet expectations for high-quality photo prints.
  • A small amount of ink can be left in the bottle after filling, leading to potential waste or the need to top off tanks later.

Ownership Tips

  • You'll be surprised how infrequently you actually need to buy black ink, even with regular printing.
  • The 'keyed' bottle really does prevent spills, but make sure it's seated perfectly or it won't drain.
  • Don't expect professional photo lab quality, especially for color photos, from the printers this ink is designed for.
  • Keep an eye on the ink levels in your printer, as the bottle might not completely empty into the tank in one go.

Frequently Asked Questions

Is this ink compatible with all Epson EcoTank printers?

No, this T522120 black ink bottle is specifically designed for use with Epson EcoTank ET-2720 and ET-4700 models, among others in the 522 series. The EcoFit bottles are uniquely keyed to fit only the correct color tank on compatible printers.

How long does a bottle of this ink typically last?

Many users report that a single bottle of this ink lasts for a very long time, with some stating it lasts over a year or even two years, depending on printing volume. Epson states it delivers thousands of pages.

Can I use third-party or generic ink with my EcoTank printer?

While some users attempt to use third-party inks, it's generally not recommended. Genuine Epson ink is formulated for reliable performance and print quality, and non-OEM inks can lead to issues like print head clogs, color inaccuracies, or faster fading.

Is the refilling process messy?

Epson's EcoFit bottles are designed with a unique keying system that prevents spills and ensures the bottle only fits the correct tank, making the refilling process straightforward and mess-free for most users.

Does this ink produce good quality photos?

This black ink bottle delivers razor-sharp text and brilliant colors for general printing. However, for high-quality photo printing, especially from lower-end EcoTank models, some users suggest that printers with dye-based black ink (like the ET-8500 series) are more suitable.

Buying Guide

When you're looking at ink for an EcoTank, you're basically buying a big bottle of liquid ink instead of those tiny plastic cartridges. This means you'll pay more upfront for the printer, but way less over time for the ink. Think of it like buying a big jug of milk instead of individual cartons – it's more efficient and cheaper per serving. The key is that these bottles are designed to refill tanks built into the printer, not replace small cartridges.

High Yield

This isn't just marketing fluff; 'high yield' for an EcoTank bottle means it contains a lot more ink than a standard cartridge. It translates directly into printing thousands of pages before needing a refill, saving you time and money by reducing how often you have to buy ink.

EcoFit ink bottles

This is Epson's clever design to make refilling mess-free. Each color bottle has a unique nozzle shape, or 'key,' that only fits into its corresponding color tank on the printer. It's like a child-proof cap, but for ink – it prevents you from putting the wrong color in the wrong tank and stops spills.

Alternatives

If you need to print high-resolution photos with archival quality, look for printers that use multiple dye-based inks, or consider a different printer technology altogether. If you're not printing much, a traditional cartridge printer might still be cheaper upfront, even with higher ink costs.
