Thank you for your time and efforts. The information helped me to better understand what some of the service options might be, but having said that, did not solve my problem. It still exists as before.
Yes, I am using genuine HP ink from Amizon.com. I installed the fresh ink supplies the day I received the Amazon shipment. The failure notice (w/o a code #) was immediate. The printer worked before the new ink was installed. It has not worked since.
Thanks. Nils K.
