ABSTRACT:
In an electrophotographic print mechanism wherein one motor drives two or more removable toner cartridges, the presence of each cartridge is sensed and reported to the motor controller. If one or more cartridges are removed, such as for single-color printing, the motor control equation parameters are altered to compensate for the altered static torque load experienced by the motor. The parameters may be the proportional, integral, and/or derivative gains for one or more PID controllers.
