Abstract

The method of operating an inkjet printing system includes ejecting usable fluid on a substrate in a print mode and in a purge container in a maintenance mode by a print head. The method also includes receiving recovered fluid from the purge container and source fluid from the source supply to form the usable fluid in a primary fluid tank. The method also includes receiving and providing an amount of the usable fluid from the primary fluid tank to the print head by at least one of a first supplemental fluid tank and a second supplemental fluid tank. The method also includes determining a consumed amount of the usable fluid corresponding to an amount of the usable fluid used by the print head reduced by an amount of the recovered fluid received by the primary fluid tank from the purge container.
