Sure color P600 ink installing problem

My first P600 printed fine, but had to get a replacement from Epson since roll papers weren’t feeding automatically. now reinstalling inks, printer says to replace cartridges…tried taking sensor switcher out and back in several times…which worked previously on my first printer, but not on this one. tried turning g off, on, unplugging etc…nothing. 2 inks read ok LK and MK…any thoughts ?

Did you take the carts out with the cover sensor switch still in?

Time heals ! after a day, the printer accepted the inks…I still have to remove the sensor switcher and replace it almost every time I print since there is usually at least one ink cart that says its out of ink.
