Abstract (en)
[origin: EP0782928A1] Described herein is a color printer (100) which uses multiple linear arrays (102) of surface emitting lasers of the same wavelength to simultaneously expose widely separated positions on a plurality of photoreceptors (140, 142, 144, 146). Modulated light beams (120, 124, 128, 132) from each array (102) is imaged by a first telecentric spherical lens group (134), an aperture (136) and a second telecentric spherical lens group (138) onto the photoreceptors (140, 142, 144, 146). The modulated light beams (120, 124, 128, 132) are angularly spaced from the aperture (136). The multiple linear arrays (102) can be closely spaced in a monolithic structure. <IMAGE>
