Abstract
A continuous web substrate duplex (both sides) printing system which can utilize a single otherwise conventional or existing xerographic print engine (normally printing conventional cut sheet print substrates) without substantial structural modification, instead of requiring plural print engines on opposite sides of the web. This may be accomplished as shown by operatively docking a special duplex continuous web printing substrate supply module with the cut sheet print engine to form an integral duplex web printing system. Here, this duplex web printing module has an integrated fusing system with translating and half-surface-speed roll fusers for fusing the transferred images on both sides of the web with those two separate moving fusers, with each fuser fusing images on one side of the web after respective separate transfers of sequences of plural first and second web side images. One of these moving fusers is fusing the first side images in an expanding and contracting web loop section of the endless web in between first and second side image transfer stations.
