How to Unlock Print Heads on Epson SureColor P6000

I’m ready to enter the wonderful world of actually maintaining my P6000, but can’t figure out how to unlock the print heads. IJM doesn’t seem to have a video on this model, and I haven’t been able to find the relevant info elsewhere. Does anyone know what the secret is?

Well. The best way to do it is to turn printer off, take right cover off and then you can access everything that you need to clean including the printer head port.
