ABSTRACT:
A system for measuring a percentage of the solids in a liquid developer material is provided. The liquid developer material is received by a liquid developer material application member for application of the liquid developer material to a selected surface. The liquid developer material, when disposed on the developer application member as a film, is characterized by a first value varying as a function of developed mass per unit area (DMA) and a second value varying as a function of film thickness. The measuring system includes: a first sensing system for determining a magnitude corresponding with the first value; a second sensing system for determining a magnitude corresponding with the second value; and a controller, responsive to the first and second sensing systems, for determining the percentage of the solids in the liquid developer material with the determined first and second values.
