The printer is out of color ink even though I print in black only. Why does this happen?

To keep the print head clear, the printer uses a small amount of ink from all the cartridges whenever it prints. Even if you set the printer software to print black only, some color ink is still being used. If you need to speak to our customer service staff, call us at 1-833-777-0127.
