Abstract
A xerographic printing system is constructed using a field emission device 120 as a modulated light source. Alternatively, a lens 122 may be disposed between the field emission device 120 and the photoreceptor drum surface 106. The field emission device 120 may project a single pixel row, or may project multiple pixel rows which provide gray scale capability. The field emission device 120 may also provide color print capability.
