522 Ink Refill Bottles for ET-2800 ET-4800 Printers - High Capacity

In this review the 522 ink refill bottles are evaluated as a budget-focused refill option for owners of compatible Epson-style tank printers. The bottom line: this 6-pack is best for users who want high capacity ink and simple, low-mess filling for frequent document printing. It stands out for an auto-stop nozzle that reduces spills and for a claimed yield that supports long runs of text-heavy pages, making it a practical choice for home offices, small businesses, and students who prioritize value over brand-name cartridges.

Key Features

• High capacity: The refill bottles are designed to deliver long print runs, with the black bottle sold as capable of up to 8000 pages at 5% A4 coverage, which reduces refill frequency for heavy users.
• Wide compatibility: These bottles are compatible with a long list of ET-series printers and models that accept 522 ink, so users with ET-2800, ET-2400, ET-4800 and similar machines can swap them in easily.
• Auto-stop nozzle: The bottles use an auto-stop nozzle design that makes filling straightforward, helps prevent spills or drips, and eliminates the need to squeeze the bottle.
• Sharp text and black output: The black ink is formulated for crisp text and deep blacks suitable for documents, reports, and everyday graphics.
• Cost-effective alternative: Customers report the set offers good value compared with OEM options, making it appealing for budget-conscious print-heavy users.

Who It's For

The 522 ink refill bottles are ideal for home office users, students, and small businesses that print large volumes of mostly black-and-white documents and need a low-cost refill option. If you own an ET-2800, ET-2803, ET-2840, ET-2400, ET-4800, ET-2720, ET-4700 or ET-4810 series printer, these bottles are a practical match and simplify maintenance with their easy-fill nozzles.

Users who require professional photo-quality color reproduction or who must adhere to manufacturer warranty rules for commercial printing should consider OEM supplies or manufacturer-recommended inks. Also, if precise archival color matching is required, a dedicated photo ink set may be a better fit.
