I have and HP Office Jet 4650. I have used it for almost two years, with firt a Toshiba lap top and more recently with a Dell laptop. Yesterday, I was printing a long document, the black ink ran out, I replaced the cartridge and the printer will not print anything else, I get the repeated message “to print you need to finish set up. Touch ok and follow instructions . . . ” When i do that, I then get the message briefly, “Wait until the printer finishes before you push in the output exgteder. Then I get the original message to complete set up. What shall I do?
