A method of controlling light emitting elements in an electrophotographic print head includes providing a predetermined number of pulse width modulators having different width output pulses, the predetermined number being less than the number of light emitting elements; selecting multiple light emitting elements for coupling to respective ones of the pulse width modulators; and coupling the multiple selected light emitting elements to the respective pulse width modulators. An electrophotographic printer includes a print head having a predetermined number of light emitting elements; a predetermined number of pulse width modulators having different width output pulses, the predetermined number being less than the number of light emitting elements; and logic circuitry configured to couple multiple light emitting elements to respective ones of the pulse width modulators.
