Product: HP ENVY Pro 6458 All-in-One Printer

I have an HP Envy Pro 6400 series printer and replaced both the tri-color and black ink cartridges. The color cartridge works, but the black one does not. I've tried two new black ink cartridges (original HP ink), but neither works. The printer and HP Smart app recognize the black cartridge and indicate that it is new (full). I've gone through all the troubleshooting steps suggested by the virtual assistant, but it has not resolved the problem. Are there other steps I can take to fix the problem?
