All I can say is, WOW and THANK YOU SO MUCH! That was so simple! When searching online last night for hours, I never saw anything that told me the FIRST thing I needed to do was restore the printer's network settings by pressing and holding both the "WiFi" and "Cancel" buttons until the power light started blinking and I'm not smart enough to know that it needed to be done.
Again, thank you so much for your advice and blessings!
