I have an HP 8710. I just replaced the black ink cartridge. The printer is saying I have to replace all cartridges….This were the starter cartridges. We print mostly in black so I cannot imagine the others are out???

Even if you print mostly in black, the printer still uses small amount of ink from all the colored ink cartridges for servicing task. If you prefer to print only in black I would recommend you to change the settings in the HP software to print in Black & White, Black Ink Only, or Monochrome: ( to print only with black ink)
