• Qualitative Reasoning Based Adaptive Controller
Qualitative Reasoning Based Adaptive Controller is adaptive control on the basis
of quantative reasoning theory. While successively reasoning and learning the
change of process characteristics regardless of environmental changes and the
variations with time and the number of copies on the copier, the system reads the
patch marks and determines the best values of exposure and surface potential to
establish the best gamma curve for optimum copy quality.
• Qualitative Reasoning Based Adaptive Controller is applied at the following intervals.
a) During initialization after turning on the power.
b) After every 1,000 sheets following execution of Qualitative Reasoning Based
Adaptive Controller
(But, every 200 sheets following the execution of F8-09 for the next
500 sheets)
c) After turning on the power (up to 200 copies)
d) After replacing the toner bottle (up to 200 copies)
• Copy density detecting sensor
Two sensors for detection of copy density are used, one for white density, and line
pattern density and one for detection of black density. (Temperature and humidity
sensors are not used.)
• To correct for toner build up on the sensor, clean the sensor at the same time as
the replacement of the drum. The system provides a measured amount of light
and detects the reflected light. The resultant value is used for sensor compensation.
This becomes the reference value.
• As the reference value of the white density changes, various components are
adjusted according to characteristics of the gamma curve.
