(54) An apparatus for line-to-line recording of different color component images


(57) An apparatus for line-to-line recording of different color component images. Four separate xerographic type processing units (111, 112, 113, 114), one for each of the primary colors plus black, are arranged in close nested relationship to one another with image transfer stations (68, 69, 70, 71) in close succession along the path of movement of the copy sheets (12). A combination air flotation type (35) and vacuum based belt transport system (55) is used to move the copy sheets (12) from supply tray (27) successively past the processing units. Exposure is simultaneous. A precise. dimensional relationship between the length (L) and spacing (D) of each photoreceptor belt (110) assures registration of the color images with one another.
The length of each photoreceptor belt (110) is the same. Vacuum tensioning means (122) provides the preset dimensional relationship (L, D) between each photoreceptor belt (110). Plural flying spot beams (261', 262', 263', 264') derived from laser (222) provide simultaneous exposure of each photoreceptor belt.
