Theory of Operation
The Dispense Count is implemented over the next eight prints. For example, if
the Dispense Count is 16, two dispense counts are added during each of the
next eight prints. This is in addition to any counts added or subtracted during
each print as a result of PCDC.
If the CTD (ADC) Sensor indicates that toner density is too high and that 16
Dispense Counts are required to return toner density to normal, the
adjustment is accomplished by subtracting two counts from the calculated
PCDC count over each of the next eight prints. If the excess amount cannot
be subtracted in 8 print cycles, it is subtracted in the ninth and subsequent
prints. The following figure illustrates this process.
High Area Coverage Mode
The High Area Coverage mode delays page feeding giving the printer
additional time to dispense toner. This mode compensates for images whose
toner density exceeds the printer’s toner dispense capabilities. This typically
occurs during continuous runs of images that drop the toner density for any
color Developer below the reference value.
Admix Mode
If High Area Coverage mode fails to compensate for the reduction in
Developer toner density, or if the printer is moved to an environment with a
different humidity level changing the reference value, Admix mode dispenses
toner immediately to restore toner density levels if needed.
