  • Method of controlling rotational velocity of a rotatable member during encoder initialization for an imaging apparatus
    Patent number: 6873129
    Abstract: A method of controlling a rotational velocity of a rotatable member during initialization of an analog encoder unit that generates a channel A signal and a channel B signal, includes the steps of processing the channel A signal and the channel B signal to generate a feedback signal, an integrity of the feedback signal being maintained even if only one of the channel A signal and channel B signal is functional; and controlling the rotational velocity of the rotatable member during the initialization of the analog encoder unit based on the feedback signal generated by processing the channel A signal and the channel B signal.
