Hi there and welcome
can you first remove the power to the printer (so unplug it from the power socket) then wait 10 minutes.
Then connect the power, turn on the printer and tell me if it then allows you to printer.
Let me know the results please.
Are you printing from a windows or a mac computer?
I want to see if the printer is ok, and to do this we do a nozzle checl
Does it then do the Nozzle check?
