HP Photosmart 6510 suddenly stopped printing black

HP Photosmart 6510
macOS 10.15 Catalina

After years of pretty reliable service, I cleared a paper jam and suddenly cannot print any black at all.  I have put in a new HP cartridge without any improvement, have tried disconnecting for a reset, and have cleaned the printhead.  Colors are printing perfectly but no black.  HELP!!
