Abstract

See full text

An apparatus for providing delay signals to perform print scan line synchronizations within a laser printer is disclosed. The apparatus includes a voltage-control oscillator, a frequency divider and multiple output control modules. The voltage-control oscillator converts a clock signal to a higher frequency signal. The frequency divider then reduces the frequency of the higher frequency signal. Then, each of the output control modules generates a delay signal, and each of the delay signals is delayed by no more than one tenth of a clock cycle from an adjacent one of the delay signals.
