Abstract
An intermediately fluid supply apparatus is to fluidically couple a primary fluid supply to one or more fluid-ejection printheads. A reservoir of the apparatus has a bottom surface and a number of side surfaces, and is open at the top of the reservoir. The reservoir is to store fluid supplied by the primary fluid supply, for ejection by the fluid-ejection printheads. A flexible membrane of the apparatus seals the top of the reservoir. The flexible membrane is to expand and contract over the reservoir in accordance with the volume of the fluid currently stored within the reservoir. A sensing mechanism of the apparatus is to directly or indirectly sense the volume of the fluid currently stored within the reservoir.
