Sensor Maps

Sensors in the printer provide information to the main board to determine the state of the
printer. The printer monitors the positions of some of the movable assemblies, such as the
drum, as well as the temperature of many other assemblies, such as the printhead, paper
preheater and the drum.
Unlike the Phaser 840 printer, the Phaser 850 /860 printer does
