2 Calibration
Information
Lists the last color-plane registration (CPR) page count, the last CPR page-count date,
the last page count (in engine cycles) for DMAX/DHALF, and the last DMAX/DHALF
page-count date.
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%.
