Epson EcoTank ET-2650 Ink Bottles
Your Epson EcoTank ET-2650 uses the T664 cartridge series, which relies on high-capacity refill bottles rather than traditional plastic cartridges. Our 4.8 Google Star rating shows that our customers consistently receive high-quality cartridges backed by reliable performance. Having supplied dependable consumables for this printer since Sep 2017, we understand the specific replacement behaviour of home office users who print continuously for months or years between top-ups due to the vast reserves of the integrated reservoir system.
Expected page output and replacement cycles
Real-world longevity depends on document layout coverage, though Epson measures standard output volumes using the international ISO/IEC 24712 benchmark for continuous inkjet printing. Unlike classic setups, these high-capacity bottles allow users to print thousands of pages before needing to monitor fluid levels.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|

| C13T664292 | Standard | Cyan | 6,500 | $0.003 |

Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Choosing the right cartridge setup
Home environments running regular multi-page colour jobs find that bundle sets offer the best path to balancing all four reservoirs simultaneously. If you primarily generate monochrome records or text invoices, buying standalone black ink bottles alongside the multi-packs prevents premature depletion issues. Free delivery applies on all orders over $99 (conditions apply), with stock dispatched rapidly from our regional supply centers across Perth, Brisbane, Sydney, Melbourne, and Adelaide. To secure your purchase with complete confidence, view our official returns policy or check options for other models under the wider Epson ink bottles category.
Pro Tip
Never fill the ink reservoirs past the upper fill line indicated on the translucent plastic casing, as overfilling can disrupt the internal air pressure equilibrium of the fluid lines, causing internal leakage or immediate printhead dripping during printing.
Frequently Asked Questions
Can I save a partially empty T664 bottle for a later top-up?
Yes, you can recap the bottle tightly and store it upright in a cool, dark environment. The specialised nozzle seals securely, keeping the remaining liquid fresh until the internal reservoirs drop low enough to accommodate the rest of the fluid.
Why does my black ink tank require filling more frequently than the colour reservoirs?
Standard text documents utilise the independent black channel exclusively, whereas everyday colour graphics distribute their workloads across three distinct reservoirs, meaning your black ink levels will naturally diminish much faster in typical office environments.
How do I track fluid consumption if these bottles do not have electronic microchips?
The printer relies on regular visual inspections through the transparent windows located on the front of the housing; waiting for a software notification is unsafe, as running the system completely dry can pull air into the fluid delivery lines.
