Toner Density Adjustment Mode
Overview
Process control adjusts the toner density so that
the density of each colour in the image is correct.
But, sometimes, process control adjusts the
toner density too slowly, and the first few copies
after process control have incorrect toner
densities.
Toner density adjustment mode brings toner
concentrations to the correct values much more
quickly.
