Abstract
A method of controlling a DC motor is presented. In a tracking action, an input to the motor is tracked. In a comparing action, the input is compared against a baseline value. In an adjusting action, a usage of the motor is adjusted when the input passes a threshold related to a motor performance parameter. A method of estimating a parameter of an ink carriage moved by a DC motor is also presented. In a tracking step, an input to the motor is tracked. In a comparing action, the input is compared against a baseline value to predict a level of the parameter.
