Epson printers does not recognize ink or toner

Epson printers (EcoTank, Expression and WorkForce Pro) does not recognize ink or toner: exact part compatibility, shipping seals, contacts, seating and firmware should be checked before replacement. Scoped to EcoTank ET-4850 (C11CJ60202), with the other Epson EcoTank, Expression, SureColor and WorkForce Pro models in the model notes.

EcoTank printers use bottled ink and tanks, so the equivalent of a cartridge error is an ink level or tank message. Epson's guidance for the reset message is exact: if the LCD prompts you to reset ink levels, refill all of the ink tanks, or the ones indicated, all the way to the top, select the colors you refilled on the LCD and follow the instructions to reset the ink levels.

The checks in more detail

Depending on operating conditions you may see the reset message even when there is still ink in the tanks. Epson explains that the product has a low ink alert system that cannot measure the ink directly, it estimates the amount remaining by monitoring usage, and that the system may give inaccurate messages if the tanks are not refilled according to the instructions. As a precaution inspect the tanks regularly so ink does not fall below the lower line, because continued use below the lower line could damage the product.

If you refilled but the printer still says low, reset the levels. On WorkForce Pro models that use ink packs, reseat the pack, check it is the right model and that the packing tape is off; an unrecognized pack may be a wrong-region or damaged one. Use genuine Epson ink, since third-party ink can cause errors. Ink pad codes E-11 and W-11 are separate and need Epson.

Keep the bottle keys and packaging with the printer, and note which bottle went in which tank, since Epson's low ink alert only works if you refill to the top and reset. If the low ink message appears right after you refilled, you probably need to reset the levels, and if it appears when the tank is clearly full, reset anyway. Refill in good light, tank by tank, wiping drips at once, and reset the levels straight after so that the printer's estimate starts from a true full tank.
