Information or capability that the area provides
Color plane registration occurs when new print cartridges are installed to compensate
for any slight variations that might occur in cartridge circumference.
DMAX is a density calibration of each print cartridge color at 100% coverage; DHALF
is also a density calibration of each print cartridge color, but as a halftone instead of
a full color. During halftone printing, the dots of toner are spread out, and coverage of
the toner is less than 100%.

Lists the cyan, magenta, yellow, and black (CMYK) values for highlights, midtones,
and shadows.

Parameters
For color devices, specific engine settings related to the printing or
electrophotographic process are critical in identifying device status and function. The
electrophotographic parameters, which are used to detect, diagnose, and track print-
quality defects, appear in a 272-cell binary array that contains the settings registered
by the device engine. These registers also appear at the bottom of the

screen.
