Epson EcoTank ET-2850 Ink Bottles
Your Epson EcoTank ET-2850 uses the T502 ink bottle series, engineered for reliable daily documentation. Our 4.8 Google Star rating shows that our customers consistently receive high-quality cartridges backed by reliable performance. We have been supplying consumables for this printer since Oct 2021, supporting its integrated four-colour system. Home office users notice distinct replacement behaviour across tasks; because text relies solely on the pigment black reservoir, standard black ink consumption moves independently from the three dye-based colour channels used for graphics.
Expected page output and replacement cycles
Epson measures the fluid volume of these T502 ink bottles according to the continuous test standard of ISO/IEC 24712 patterns, which simulates normal office documentation rather than solid photographic prints.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| T502 | Standard | Black | 7,500 | $0.005 |
| T502 | Standard | Cyan | 6,000 | $0.003 |
| T502 | Standard | Magenta | 6,000 | $0.003 |
| T502 | Standard | Yellow | 6,000 | $0.003 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Stocking your replacement bottles
Prioritising your fluid refills according to typical document distribution keeps your printing flow steady. Daily homework or report writing depletes the larger black reservoir, whereas colour bottles remain stable for longer periods. For consistent, long-term administrative tasks, bundle packs offer a balanced solution to hold on standby. Our return framework is managed directly via our Returns policy page. Free delivery applies on all orders over $99 (conditions apply), fulfilled from our regional supply network situated in Perth, Brisbane, Sydney, Melbourne, and Adelaide.

Pro Tip
When refilling the fluid wells, match the specific bottle nozzle to the matching tank slot keying mechanism precisely, and avoid squeezing the bottle forcefully to prevent hydraulic backpressure from spilling ink onto the internal chassis.
Frequently Asked Questions
Why does my black T502 ink run lower than the three colour channels combined?
General office administrative work comprises text characters that tap exclusively into the pigment-based black fluid line. The cyan, magenta, and yellow bottles contain dye-based formulations reserved for visual graphs, graphics, or image layouts, meaning their depletion path stays low during text runs.
Can I store a half-empty T502 bottle safely after topping up my reservoirs?
Yes, each T502 refill cap incorporates an airtight seal structure that protects the fluid from ambient degradation. Ensure the cap is threaded securely and sit the bottle upright in a cool, shaded workspace to maintain correct fluid stability for your next top-up.
What happens if I receive a low-ink alert but the ET-2850 fluid tank looks partially full?
The internal alert threshold works on an algorithmic counters estimate rather than direct physical monitoring inside the reservoir walls. Visually verify the fluid level against the clear front window line to confirm if an actual refill is necessary before resetting the ink system status.
