Abstract
A method of the invention is for controlling a DC printer motor with a motor driver during a potential stall of the DC printer motor. One step of the method includes detecting the start of the potential stall of the DC printer motor. Another step includes thereafter during the potential stall using an input to the motor driver which corresponds to a pulsed desired motor voltage. A further step includes outputting from the motor driver a control voltage to the DC printer motor based on the input. In one example of the method, the start of a potential stall of a DC printer motor is detected at least one time when a printhead carrier moved by a DC printer motor of an inkjet printer encounters a capping device of the inkjet printer while returning to the printer sidewall home position of the printhead carrier.
