Abstract: A system for reproducing the image on a document comprises a scanning system including a galvanometer driven mirror which reflects a collimated image of an illuminated band via a focusing lens system onto a line array of photosensitive elements. Relative movement between the scanning system and the document causes the scan of successive bands across the document, generating signals at the photosensitive elements that represent line image variations. The photosensitive elements are arranged in 1:1 correspondence to individual ones of a line array of ink jet printers disposed adjacent a copy document. Both the signal generating and image reproducing systems scan their associated documents in synchronism so that the image may be reproduced in direct fashion or using interleaving for higher density with given inter-element spacing. Such systems may provide real time copy, reproduction with or without change of image size and insertion of digitally generated data, or electronic processing may be used for altered or delayed reproduction.
