Printer Calibration:


At the start of all this is the calibration cycle. The printer will calibrate itself whenever the printer is turned on, when a new


toner cartridge is installed, after 48 hours of run time, and at 150 page intervals. Calibration consists of a solid block and


halftone of each color being printed to the ETB. As the printed areas get to the top of the belt, a sensor will detect them,


measure the density, and adjust the printer accordingly. All of the calibration time settings are user controllable. There are


also physical calibrations of the gear train, and various rollers.
