56:"Save Queue" where they could be retained, edited if desired (using the built in editor), and later printed "on demand". The system was also capable of printing on sheet sizes up to 14x17 inches. Another important feature of this earliest DocuTech was its ability to perform signature imposition and generate "2-up signatures" (later 4-up was added) in the proper page imposition order to create signature booklets. (note: Folding, trimming, and stitching of booklets was done by an optional accessory known as a C.P. Bourg Signature Booklet Maker or SBM-1, which could be attached in-line to the system's output finisher.)

the light-lens optics and exposure lamps found in the "analog" 5090 system. The system's scanner module allowed document scanning in a number of modes including manually from the platen or automatically using a 23 page-per-minute recirculating document feeder. The scanner also had a semi-automatic side feeder which could be used to scan large originals and computer fan-fold (CFF) input. The entire system was controlled by an electronic sub-system (ESS) of a proprietary Xerox design. The ESS incorporated a large number of Xerox proprietary

The original DocuTech
Production Publisher was capable of scanning and then printing black-and-white pages at up to 135 pages per minutes (for letter or A4 sizes) with an output resolution of 600 x 600 dots per inch (dpi). Scanned documents could be saved to a special memory area on disk known as the

In late 1991, Xerox re-branded the original DocuTech
Production Publisher as the DocuTech Production Publisher Model 135 (DT135). This was done to distinguish it from the DocuTech Production Publisher Model 90 which the company anticipated announcing in 1992. The model numbers were chosen to reflect

processors which were specifically designed for high-speed image processing, 32 MegaBytes of RAM, I/O control interfaces for communicating with the
Printer and Scanner modules, as well as 3 disk drives which contained system software and space for storing images (including those for saved jobs). The

print engine and attached finisher module were largely based on ones previously developed for the Xerox 5090 Duplicator system (announced by Xerox in 1988). However, image generation in the DocuTech was performed using a digitally driven, dual-beam, Laser ROS (Raster Output
Scanner) rather than by

In June 1992 Xerox announced the DocuTech 135 Network
Publisher which augmented the earlier DocuTech's capability by enabling it to receive and print documents transmitted over a network. Although this system's network connectivity was limited to Xerox's proprietary

With its ability to digitally scan, edit and store documents for later retrieval, and also its ability to output stitched or tape-bound books, the DocuTech
