Abstract
An inkjet printing system includes an ink container adapted to hold a supply of liquid ink therein and a printhead communicating with the supply of liquid ink via a flow path. A pressure sensor measures a pressure of liquid ink disposed in the flow path and a volume detector detects a volume of liquid ink delivered through the flow path. In addition, a leak indicator communicates with the pressure sensor and the volume detector, and indicates an ink container leak based on the pressure of liquid ink disposed in the flow path and the volume of liquid ink delivered through the flow path.
