I assume this is the T790. I suggest you remove all the printheads and ink cartridges and turn the printer off. Now turn it back on and wait till it tells you to put in the supplies and then do it and see what happens.

Did you close the printhead cover on the carriage assembly when you removed the printheads?

HP Recommended

Yes, I did.

Same error as from the start.
