What Ink Does the Epson EcoTank ET-15000 Use?

by Last Updated:

Quick answer: The Epson EcoTank ET-15000 uses Epson 502 ink bottles. The printer ships with a double-size Black bottle (127ml) plus standard-size Cyan, Magenta, and Yellow bottles (70ml each), and uses the same 502 replacement bottles going forward.

INK BOTTLES AT A GLANCE

Bottle Color Approx. Page Yield
Epson 502 Black ~4,500 pages
Epson 502 Cyan ~7,500 pages
Epson 502 Magenta ~7,500 pages
Epson 502 Yellow ~7,500 pages

The same Epson 502 bottles are used across much of Epson's EcoTank lineup, including the ET-2720, ET-2750, ET-2760, ET-2850, ET-3760, ET-3850, ET-4750, and ET-4760, so a single ink set covers several EcoTank models if you own more than one.

HOW TO REFILL INK IN THE ET-15000

  1. Open the ink tank cover on the front of the printer and unlock the tank cap for the color that's low.
  2. Snap off the bottle cap and place the bottle into the matching color tank port.
  3. Let the ink flow naturally — bottles stop automatically when the tank is full.
  4. Replace the bottle cap and close the tank cap firmly.
  5. Close the ink tank cover; the printer recognizes new ink immediately.

TROUBLESHOOTING TIPS

  • Print quality issues: Run two or three Print Head Cleaning cycles from Setup > Maintenance and print a nozzle check.
  • Ink not flowing: Make sure each bottle is fully seated; the keyed bottle tip releases ink automatically.
  • Ink levels look low after refill: Use the LCD menu to manually reset each ink level after a refill.
  • Printer won't prime after first setup: Run the power cleaning cycle from the maintenance menu; if nozzle checks stay blank afterward, contact Epson support since this can indicate a factory defect.
