Abstract
When a first fluid supply of a fluid-ejection device is empty and a second fluid supply of the device has a non-empty fluid amount less than a threshold, the device performs an action related to the second fluid supply. After the action has been performed and both the first and second fluid supplies have been replaced, the device primes the first and second fluid supplies. The action can include emptying the second fluid supply, and then messaging that both the fluid supplies require replacement. The action can include messaging that both fluid supplies require replacement although the second fluid supply is not empty. The action can include not messaging even that the first fluid supply requires replacement until the second fluid supply also becomes empty.
