Cyan is where the 664 family's split personality resolves: whatever black your printer takes, its cyan is this bottle. Our compatible T664220-S holds 70 mL of cyan ink rated up to 6,500 pages (ISO/IEC 24712, Epson methodology — the family's conservative figure), and it serves all eight 664-generation models: ET-2500, ET-2550, ET-2600, ET-2650 and ET-4500, whose black is also 664 — plus ET-3600, ET-4550 and ET-16500, whose black is the 774 bottle but whose colors stayed 664.
That makes this the one product line in the family with no boundary to memorise: if your EcoTank is a 664-generation model, its cyan tank takes this bottle. Epson's own Ink Finder lists T664220-S for all eight printers, Group A and Group B alike — the colors are the shared layer of the whole generation.
On yield, the family footnote applies to colors too: some later model pages (ET-2600/2650) print 7,500 for these bottles while the reference pages print 6,500. We carry the conservative 6,500 on every 664 product, so the spec never depends on which model page you arrived from. Keyed EcoFit nozzle, auto-stop fill, no chip. Covered by our lifetime warranty, with free returns for the first year.

Frequently Asked Questions
Which tank and which printers?
The cyan tank of all eight 664-generation models: ET-2500, ET-2550, ET-2600, ET-2650, ET-4500, ET-3600, ET-4550 and ET-16500 — verified model by model in Epson's Ink Finder listings.
My ET-16500's black is a 774. Is its cyan really 664?
Yes. The split on the ET-3600, ET-4550 and ET-16500 is only about the black: Epson specs those printers as 774 black + 664 colors. This cyan is correct for all three.
What yield should I plan around?
Up to 6,500 pages per bottle (ISO/IEC 24712, Epson methodology). It's the family's conservative figure — see the next answer for the higher number you may have seen.
Why do some pages say 7,500 for this bottle?
Epson's ET-2600/ET-2650 pages rate the same color bottles at 7,500 while its ET-2500/2550/4500 pages say 6,500. Both are official; we spec the lower figure on all 664 products so nothing is oversold.
What type of ink is 664 cyan?
Epson's US documentation for this family states no ink type (its spec fields read only "EcoTank Ink Bottles"), so this page claims none. Documented facts here: code T664220-S, 70 mL, the yield above, and the eight-model list.
Does the bottle have a chip?
No. Bottles are chipless; the keyed nozzle seats only on the cyan tank and the fill stops at full automatically.
Prints are leaning magenta. Is cyan low?
That's the usual signature — when cyan starves, magenta shows through and blues/purples take over neutrals. Check the tank window; refill and run a nozzle check.
Is this the same cyan as the 502 or 522 cyan?
No. Different generations, different bottles: 502 cyan is a 70 mL bottle for the 502 models, 522 cyan a 65 mL bottle for its own eight models. This one fits only the eight 664-generation printers listed here.
Can I refill just the cyan tank?
Yes — tanks are independent. Group A owners also have the 4-bottle set for full resets; Group B owners refill colors as singles alongside the 774 black.
How do I store a part-used bottle?
Capped, upright, room temperature, away from sunlight.
Is this genuine Epson ink?
No — a Clever Supplies compatible bottle built to the T664220-S specification, labeled compatible on the box and this page.
Warranty and returns?
Lifetime warranty: if the bottle ever fails to perform, we replace it. Free returns within the first year.
