Epson 502 ink fits select ET and ST printers, so choose it by your full printer model and required ink number. Once you've confirmed compatibility, buy the bottle or pack that matches the tanks running low.

These options cover black, cyan, and magenta refills, plus a color combo pack. The combo pack contains cyan, magenta, and yellow, without black, so it isn't a complete refill set for every tank.

Which printers use Epson 502 ink?

Epson 502 ink fits the specific ET and ST models below. Match every letter and digit, then confirm the ink number in your printer's manual before ordering.

• ET-2700 and ET-2800 groups: ET-2700, ET-2750, ET-2760, and ET-2850.
• ET-2900 group: ET-2980, ET-2985, and ET-2988.
• ET-3700 and ET-3800 groups: ET-3700, ET-3710, ET-3750, ET-3760, ET-3830, ET-3843, and ET-3850.
• ET-3900 group: ET-3930, ET-3943, ET-3950, and ET-3958.
• ET-4700 and ET-4800 groups: ET-4750, ET-4760, and ET-4850.
• ET-4900 group: ET-4950, ET-4955, and ET-4958.
• Other ET model: ET-15000.
• ST models: ST-2000, ST-3000, ST-4000, ST-C2100, and ST-C4100.

These groups make the model numbers easier to scan; they don't imply that every printer within a number range uses 502. A similar model name isn't enough to confirm a match.

For background on refillable tanks, read what an EcoTank printer is and how it works. Our Epson EcoTank guide covers related model and upkeep topics.

Does Epson 502 ink fit the ET-2800?

The ET-2800 isn't among the compatible models named for these bottles. Check its manual or Epson support for the required ink number.

The ET-2850 is compatible, but that doesn't guarantee compatibility for the ET-2800. Read the model label on your printer rather than relying on the name remembered from an earlier order.

Are Epson 502 and 522 ink the same?

Don't treat 502 and 522 as interchangeable. Use the ink number specified for your exact printer, even if the bottles look alike or come from the same brand.

Check compatibility before breaking the seal. If the printer manual and the bottle packaging don't agree, resolve the mismatch before filling a tank.

Bottle shape and ink color aren't substitutes for this check. Never alter a bottle tip or transfer ink into another container to make an uncertain refill fit.

Which Epson 502 bottle suits your printing?

Choose an individual bottle for one low tank and the color combo pack when several color tanks need attention. These are supply choices for different refill needs, rather than competing upgrades to print quality.

All 4 options are genuine Epson ink with uniquely keyed EcoFit bottles. Epson recommends genuine ink for print quality and performance, and warns that damage caused by non-genuine ink may fall outside its limited warranty.

Black: for document-heavy printing

The black bottle suits a compatible printer whose black tank needs refilling while its color levels remain adequate. It's the focused choice for a household or office that mainly prints text and has used more black than color ink.

Skip this bottle if your only low tank is a color tank. Black ink won't replace a missing color, and a full black tank doesn't remove the need to keep the other inks available.

Epson notes that all colors are used for printing and maintenance. Even if you mostly print documents, check every tank before a long print job rather than stocking black alone.

Color combo pack: for several low color tanks

The color combo pack suits buyers who need several colors together, especially when yellow needs refilling alongside the other colors. It's also a sensible choice when your usual work includes color worksheets, charts, and graphics that draw down several tanks.

Skip the pack if you only need black or if one color is low while the others remain well supplied. Buying several bottles doesn't mean you should open them all or top up tanks that don't need ink.

For a yellow-only refill, this pack includes the needed color among the options here. Compare that need with your remaining supplies so you don't build up more spare bottles than you'll use.

Cyan: for one low cyan tank

The individual cyan bottle suits uneven color use when cyan is low and the other tanks still have enough ink. Repeated designs with large blue or green areas can make a single-color refill useful, though actual use depends on print settings and image content.

Skip it when several color tanks need refilling together. In that situation, check the combo pack against your needs before ordering individual bottles separately.

Don't buy cyan solely because a photo has an odd color cast. First check the ink level and nozzle pattern, since a print problem can need maintenance rather than more ink.

Magenta: for repeated color projects

The individual magenta bottle suits a low magenta tank when your other supplies are still adequate. It's useful for repeat projects whose color coverage leaves the tanks at different levels.

Skip it if you need a broader color refill or have no sign that magenta is low. A faded red area alone doesn't prove the tank needs more ink.

Check both the visible ink level and your printer's maintenance guidance before ordering. This helps separate a supply need from a nozzle problem without buying bottles you don't yet need.

How do you check the right Epson 502 bottle?

Match printer model, ink number, and tank color, then check what you already have at home. This short check prevents wrong-family orders and duplicate spare bottles.

1. Read the full model number on the printer.
2. Confirm the required ink number in the manual or Epson support information.
3. Inspect each tank level using your model's instructions.
4. Choose the individual bottle or pack that covers those needs.
5. Compare the order with any unopened spares before buying.

Don't choose by “ultra-high capacity” alone. Epson notes that ink yield varies with image coverage, settings, temperature, humidity, and printing frequency, so it isn't a fixed refill schedule.

A printer warning can also concern a different supply. Our guide to Epson EcoTank maintenance boxes explains that separate upkeep item.

How do you refill and store Epson 502 ink?

Refill the matching tank on a level surface, following your model's instructions for bottle placement and fill limits. Prepare the area before opening the bottle so you don't need to move open ink around.

Place a protective sheet beneath the work area and keep the tank labels visible. Check the color name on the bottle against the tank label rather than judging the liquid's appearance.

Epson describes autostop technology for the combo pack and individual cyan and magenta bottles. Let the bottle work as directed, and don't squeeze it or force more ink into a tank.

Close the tank caps and printer cover when finished. If your printer asks you to confirm or reset an ink level, follow its instructions and make sure the setting reflects the actual refill.

Recap any remaining ink promptly and store bottles upright, away from heat, direct sunlight, children, and pets. Keep each bottle with its original label so the ink number and color stay clear.

Use our EcoTank refill guide for the filling process alongside your manual. Never pour excess ink back out of a printer tank to recover it.

What if an Epson EcoTank prints without yellow?

Check the yellow level and nozzle pattern before buying more ink. A missing color can need a refill or print-head maintenance, and adding ink to an adequately filled tank won't address a blocked nozzle.

For a compatible printer with low yellow ink, the combo pack supplies that color. If the level is adequate, use the printer's nozzle-check function and follow its guidance on cleaning.

Avoid running repeated cleaning cycles without checking the result or observing the manual's limits and pauses. Cleaning uses ink, so more cycles aren't automatically a better response.

Start with why an Epson EcoTank may not print yellow, then use our Epson EcoTank print head cleaning guide if maintenance is needed.

How much spare ink should you keep?

Keep spares for colors you regularly use, rather than opening a full set at every refill. Check levels before large projects and record which bottles you already have.

If the printer sits unused for long periods, avoid treating extra ink as the solution to poor output. Read whether EcoTank ink dries out when you print rarely for care advice suited to occasional printing.

If you're still choosing a printer, our ink tank printer guide helps connect refill needs with your printing habits. For an existing printer, its required ink family remains the first buying check.

Which Epson 502 ink should you choose?

Buy black for a low black tank, cyan or magenta for a single-color refill, and the color combo pack for several low colors or a refill that includes yellow. Skip any option that doesn't match your printer or current tank needs.

Before opening Epson 502 ink, make one final check of the model, ink number, and color. Then follow the EcoTank refill guide with your printer's instructions beside you.

Frequently asked questions

What printers use Epson 502 ink?

Epson 502 ink fits select ET and ST printers, including ET-2750, ET-2760, ET-2850, ET-3750, ET-3850, ET-4850, ET-15000, and ST-4000 models. Check the complete compatibility list below, then confirm the required ink number in your printer's manual before opening a bottle.

Are Epson 502 and 522 ink interchangeable?

Don't treat Epson 502 and 522 as interchangeable; choose the ink number specified for your exact printer model in its manual or Epson support information, even if another bottle looks similar. A matching brand name or tank color doesn't mean a refill is suitable.

Can I use Epson 502 ink in an Epson ET-2800?

Don't choose these Epson 502 bottles for an ET-2800 based on the ET-2850's compatibility; the ET-2800 isn't among their named compatible models. Check the ET-2800 manual or Epson support for its required ink number, and confirm that number before opening any refill bottle.

Do Epson 502 bottles stop automatically when filling?

Epson describes autostop technology for the color combo pack and the individual cyan and magenta bottles; all 4 options use uniquely keyed EcoFit bottles. Seat the correct bottle as your manual directs, watch the tank level, and don't squeeze or force a bottle to add more ink.
