Abstract of the Disclosure 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 il- luminated 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 suc- cessive 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 inter- leaving for higher density with given inter-element spacing. Such systems may provide real time copy, repro- duction with or without change of image size and insertion of digitally generated data, or electronic processing may be used for altered or delayed reproduction.
