Which Epson EcoTank Printers Use 502 Ink?
Epson 502 ink works with select ET-2700, ET-3700, ET-3800, ET-4700, ET-4800, ET-4900, ET-15000, and ST-series printers. Check your exact model before buying because Epson 522 and 552 bottles fit different EcoTank families.

Epson 502 ink works with select ET-2700, ET-3700, ET-3800, ET-4700, ET-4800, ET-4900, ET-15000, and ST-series printers. The exact match depends on your full printer model, so check the model number before buying a replacement bottle.
EcoTank is a printer design, not a single ink type. Two printers can both use refillable tanks and still need different bottle numbers.
The main mistake is treating every EcoTank printer as interchangeable. Epson uses different ink families, including 502, 522, and 552, and each has its own compatible-model list.
A close name is not enough, either. An ET-2750 and an ET-2720 look similar on paper, yet they sit in different ink families.
The same warning applies to larger models. An ET-4850 fits the 502 list, while an ET-8500 uses a photo ink set instead.
For home use, the printer model should lead the search. Start with the ET or ST number printed on the machine, not with the word EcoTank on the box.
Once you have the full model, compare it with the list for the bottle you plan to buy. If the model is not listed, choose a different ink family rather than forcing a refill.
This check is quick once the model is written down. It can save an unopened bottle, a messy tank, or a support call later.
It also helps if you own more than one printer. Keep a note of which ink number belongs to each machine.
Buy only when the printer model and the ink number match. That simple rule covers most of the confusion around Epson 502 ink.
Which Epson EcoTank printers use 502 ink?
Epson 502 ink works with ET-2700, ET-2750, ET-2760, ET-2850, ET-2980, ET-2985, ET-2988, ET-3700, ET-3710, ET-3750, and ET-3760 models. It also works with select ET-3800, ET-3900, ET-4900, ET-4700, ET-4800, ET-15000, and ST-series printers.
The compatible list includes these models:
- ET-2700
- ET-2750
- ET-2760
- ET-2850
- ET-2980
- ET-2985
- ET-2988
- ET-3700
- ET-3710
- ET-3750
- ET-3760
- ET-3830
- ET-3843
- ET-3850
- ET-3930
- ET-3943
- ET-3950
- ET-3958
- ET-4750
- ET-4760
- ET-4850
- ET-4950
- ET-4955
- ET-4958
- ET-15000
- ST-2000
- ST-3000
- ST-4000
- ST-C2100
- ST-C4100
The model number matters more than the printer's general EcoTank branding. For additional confirmation, compare your printer with Epson's printer support pages before opening a bottle.
Which 502 bottle fits these printers?
The EPSON 502 EcoTank Ink Ultra-high Capacity Bottle is the direct match for the 502-compatible models above. It is a genuine Epson black ink bottle with a uniquely keyed EcoFit design for filling the correct tank.
This bottle is a single black ink bottle. Its listed compatible models include the ET-2750, ET-2760, ET-2850, ET-3750, ET-3760, ET-3850, ET-4750, ET-4760, ET-4850, and ET-15000, plus the ST-2000, ST-3000, ST-4000, ST-C2100, and ST-C4100.
Epson describes the bottle as ultra-high capacity and recommends genuine ink for print quality and printer performance. If you are new to tank refills, follow the printer manual or read how to refill an Epson EcoTank printer before filling the tank.
What is the difference between Epson 502 and 522 ink?
Epson 502 and 522 ink are different bottle families with different compatible printers. An ET-2720, ET-2800, ET-4700, or ET-4810 needs the 522 family shown in its compatibility list, not the 502 bottle.
The EPSON 522 EcoTank Ink Ultra-high Capacity Bottle is a genuine black Epson bottle for ET-2400, ET-2720, ET-2800, ET-2803, ET-2840, ET-4700, ET-4800, and ET-4810 models.
The 522 bottle also uses a keyed EcoFit design and is described as ultra-high capacity. Its model number is T522120-S, while the 502 bottle uses model number T502120-S.
Do not swap these bottles because both are black EcoTank ink, and both are made by Epson. The number printed on the bottle and the full printer model should match before you refill.

Does the Epson EcoTank Photo ET-8500 use 502 ink?
The Epson EcoTank Photo ET-8500 does not use 502 ink. It uses Epson 552 Photo Black, 552 Black, Cyan, Magenta, Yellow, and Gray ink in a 6-color system.
The Epson EcoTank Photo ET-8500 Wireless Color All-in-One is a white wireless printer with copy functions, automatic duplex printing, a 4.3-inch touchscreen, and support for laptops, PCs, and smartphones. It prints color pages at up to 12 pages per minute and black-and-white pages at up to 16 pages per minute.
The ET-8500 includes one 552 Photo Black bottle, one 552 Black bottle, and one each of 552 Cyan, Magenta, Yellow, and Gray. Its maximum media size is 13 x 19 inches, and it supports cardstock, envelopes, CDs, and DVDs.
This model is useful as a comparison because it shows why the EcoTank name alone is not enough. A printer can belong to the same broad product family while requiring a different ink number and a different color set.
Readers comparing tank printers can use the home printer buying guide to review printer types, features, and setup needs. If you specifically need document scanning, see the best Epson EcoTank printers with ADF.
How do you check your printer before buying 502 ink?
Read the exact model number on the printer and match it with the bottle's compatible-model list. Look for the ET or ST number, including every digit after the hyphen.
Use this quick check:
- Find the model name on the printer's front, top, or control panel.
- Write down the complete model, such as ET-2850 or ET-4850.
- Compare it with the 502-compatible list.
- Check that the bottle says 502, not 522 or 552.
- Buy only after the printer model and ink family match.
Avoid choosing by appearance, color, or the word EcoTank. The 502 and 522 bottles are both black Epson ink bottles, but their compatible printer lists are different.
If you are shopping for a replacement printer rather than a bottle, check best Epson EcoTank printer sale for models that fit your printing needs. Readers who need automatic document feeding can compare the best Epson EcoTank printer with ADF.
How should you use Epson 502 ink?
Use the bottle only with a listed compatible printer, keep it upright, and follow the refill steps in the manual. The keyed EcoFit design guides the bottle to the matching tank, but it does not replace checking the model and color.
Start by confirming the black tank and the black 502 bottle match. Open the tank cap fully and place it on a clean surface, as grit from a dusty desk can get back into the tank.
Wipe any dried ink from the bottle opening with a lint free cloth and keep your fingers off the nozzle. Insert the bottle as the manual describes and let the tank fill at its own pace.
Do not squeeze the bottle or force the keyed tip into the wrong opening. Resistance is a sign to stop and check the tank again.
Rushing can cause spills that are hard to clean from the tank rim.
After filling, remove the bottle, close the tank, and check that the cap is sealed. Store spare bottles upright in a cool, dry place away from direct sunlight with the cap closed tight.
Epson recommends genuine ink for optimal print quality and performance, and non-genuine ink can cause damage not covered by the limited warranty.
Which ink should you buy?
Choose Epson 502 for compatible ET-2700, ET-3700, ET-3800, ET-4700, ET-4800, ET-4900, ET-15000, and listed ST-series models. Choose Epson 522 for the ET-2400, ET-2720, ET-2800, ET-2840, ET-4700, ET-4800, and ET-4810 models in its compatibility list.
If you print mostly black and white documents at home, the 502 bottle fits the printers in its list. It gives you a genuine black refill without changing the rest of your setup.
If your printer is an ET-2720, ET-2800, or ET-2840, do not buy the 502 bottle. Those models call for the 522 family, and black ink alone does not make the bottles interchangeable.
The ET-4700 and ET-4800 names appear in both stories, which is why the full list matters. Check the exact model and bottle number for your machine before you order.
Choose Epson 552 bottles for the ET-8500 because it uses a 6-color photo system. That printer needs Photo Black, Black, Cyan, Magenta, Yellow, and Gray, not a single black bottle.
If you are refilling an existing printer, the safest buy is the ink number already printed for that machine. Match the bottle to the manual, the tank label, or the compatible-model list.
If you are replacing a printer, judge the ink family as part of the machine. A new printer changes your refill list, so factor that in before the old bottles run out.
For color printing on a 502 printer, remember this bottle covers black only. You will still need the matching color bottles for the same family when those tanks run low, and a spare black bottle helps because many home printers use black first.
Frequently asked questions
Which Epson printers use 502 ink?
Epson 502 ink works with select ET-2700, ET-2750, ET-2760, ET-2850, ET-3700, ET-3750, ET-3760, ET-3830, ET-3850, ET-4750, ET-4760, ET-4850, ET-15000, and ST-series models. Confirm your exact printer model before opening a bottle.
Is Epson 502 ink the same as 522 ink?
No. Epson 502 and 522 are different ink families with different compatible printer lists.
502 covers models such as the ET-2750 and ET-4850, while 522 covers models such as the ET-2720, ET-2800, ET-4700, and ET-4810.
Does the Epson EcoTank ET-8500 use 502 ink?
No. The Epson EcoTank Photo ET-8500 uses Epson 552 Photo Black, 552 Black, Cyan, Magenta, Yellow, and Gray bottles.
It is a 6-color photo printer, so Epson 502 black ink is not the correct refill.
How can I avoid buying the wrong EcoTank ink?
Read the model number on the printer, then match it with Epson's compatible-model list for the bottle family. Do not choose ink by the EcoTank name alone because Epson uses different bottle numbers across its ET and ST printer ranges.
