New Digital Image Control Qualitative Reasoning Based Adaptive
Controller (New Digital QUANTUM)
To improve the copy quality, a new Toner Density Controller (New Digital QUANTUM System) was
developed.
The most important aim was to stabilize the Toner Density under various office environments.
As a result, the current QUANTUM System was improved with additional Sensors, Parameters and
Software.
The following diagram illustrates this New System.
