Table 2-8 Diagnostics Page (continued) Callout Area on the screen 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%. 2 Color Density Lists the cyan, magenta, yellow, and black (CMYK) values for highlights, midtones, and shadows. 3 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 Diagnostics Page screen. Information tab ENWW Diagnostics Page 19
