Starink 502 Black Ink Refill Bottles

For EcoTank owners who print mostly black text and want replacement ink in refill bottles, this Starink pack is listed for several printers that use 502 ink. It includes two black bottles, each with a stated capacity of 140 mL, and an automatic-stop design intended to make filling less messy. The main buying check is compatibility: this is black 502 ink, not a general-purpose refill for every EcoTank printer. Its stated page yield is also an estimate tied to a specific coverage level, not a promise for every print job.

Technical details

The pack contains two bottles of replacement 502 black ink, with 140 mL in each. The listing estimates up to 10,000 pages per bottle, or 20,000 pages total, at 5% coverage. Treat that figure as a reference point: pages with heavier text, graphics, or solid black areas use more ink, so your results may differ. The ink is intended for black text and everyday home or office printing, color ink is not included.

An automatic-stop bottle design is meant to help prevent overflow, and the listing says filling does not require squeezing. That may be useful when topping up a tank at a desk or printer stand, where a spill would be inconvenient. Still, careful handling matters—no refill design removes the need to follow your printer’s filling instructions. The listed benefit is convenience, not a guarantee that every refill will be mess-free.

Compatibility & requirements

The product is listed for EcoTank ET-2850, ET-3850, ET-4850, ET-3760, ET-2760, and ET-4760, among other models. Other named printers include the ET-3700, ET-2750, ET-3750, ET-3843, ET-4750, ET-3710, ET-3830, ET-2700, ET-15000, ST-2000, ST-3000, and ST-4000. The full list in the product information is broader, so match your exact printer model and its 502 ink requirement before choosing a refill. A similar-looking EcoTank model name alone is not enough to establish compatibility.

This is a replacement-ink option rather than an original-manufacturer bottle. That distinction matters if you prefer to stick with original supplies, if you are open to compatible refills, the useful comparison is whether the listed printer match and black-only format fit your routine. On the spec sheet, the automatic-stop feature addresses filling, while the page estimate depends on 5% coverage.

Usage tips

Set the bottle and printer on a stable surface, then follow the printer’s own refill procedure instead of relying on the bottle description alone. For a practical everyday use, topping up before a week of invoices, school forms, or other text-heavy printing can help avoid interrupting a job when the tank runs low. Keep in mind that a document with large dark blocks will use ink faster than the stated coverage-based estimate suggests.

A solid pick if your listed EcoTank model uses 502 black ink and most of your routine printing is monochrome. You may want to skip it if you need color refills, your printer’s exact model is not on the compatibility list, or you only want original-manufacturer supplies.

Questions before you buy

How many bottles are included? The listing specifies two bottles of black ink.

How much ink is in each bottle? Each bottle is stated to contain 140 mL.

Is the 20,000-page figure guaranteed? No. It is the combined estimate at 5% coverage, actual yield varies with what you print.

Should you buy it?

Choose this refill pack when your printer is explicitly listed, you need black 502 ink, and the two-bottle format suits how often you print. It gives you a stated fill aid and a large combined ink volume, but the yield figure should not be treated as a fixed number of pages in normal mixed printing. If model matching is uncertain, or you need color rather than black ink, a refill that clearly matches your printer and ink needs is the safer choice.
