Problem
I cleaned the heads but they’re still clogged.

Solution Clean them again. The fourth time in a row initiates a power cleaning cycle.

New Epson printers have anti-clogging coatings on the nozzles and initiate self-clean cycles automatically.
When power cleaning cycles don’t work you can humidify the heads (rest them no wet sponge for a while).
You’ll need to perform nozzle checks more often if you’re in a very dry environment (air conditioning dries) or you don’t use a printer for extended periods of time.
