"Not detected-incorrectly installed" message for printhead. Cleaned it. Still not working. Help

HP Recommended
hp deskjet 7520
macOS 11.0 Big Sur

My hp desk jet 7520 keeps giving me a "missing, not detected or incorrectly installed printhead" message. I use hp ink. The message began after I replaced the larger black cartridge. I looked on line and cleaned the printhead but the message remains. The printhead is securely in place, not wiggling. I also reset the printer by removing the electric cable and reinserting it. Do I need to replace the printhead?
