HP Officejet 6500A Plus suddenly won't print black and white with new cartridge

[Otono12]

My HP Officejet 6500A Plus suddenly won't print black and white either with a partially full cartridge or with a new full one. I tried with my MacBook Pro and with my iPad. Both were working fine until who knows what happened. I hardly ever print in color mode. However, my blue and red cartridges are low in ink but I just installed a new yellow one. My printer prints lightly in the color mode but not at all in the black and white mode.
