The newly controlled features and intervals are as follows.
1. Grid Voltage Feedback for Image Density Control
QUANTUM uses the Copy Density information, interpreted by the Image Density Sensors, to
control the Grid Voltage (1) [600 - 900 V] along with the Toner Density (±0.9%) and conveys it
to the Toner Density Controller as a feedback signal.
2. Long Run Operation Compensation
Under Long Run Operation Environment, the Toner Density is also controlled with the Long
Run Operation Compensation Parameter activated by the Timer / Counter (2) every 1k-sheet
interval.
3. Developer Compensation
The Toner Density is also controlled with Developer Compensation Parameter activated by
the Timer / Counter (3) when reaching the 150k, 180k and 210k-sheet count.
4. Initialization
The Developer Parameter is initialized by the Timer / Counter (4) when the machine is non
operational for over one hour.
5. Humidity and Temperature Compensation
Humidity and Temperature factors are also compensated with the Sensors (5) and the TDC
Controller Compensation Software by stabilizing the Toner Density under the various High
Temperature and High Humidity environments.
