Xerox 128 Service Manual

The Xerox DocuTech HLC printers are electronic reprographics 
systems. They are high volume printers available in multiple 
configurations. These versatile, high performance printing 
systems enable personal computers and other network-connected 
devices (such as workstations and graphic scanners) to produce 
documents incorporating graphics, forms, logos, signatures, and 
fonts.

The Xerox DocuTech HLC system consists of a DocuSP controller 
and a DocuTech printer. 

The DocuSP controller accepts electronic print input created by 
client software in ASCII, TIFF, HP PCL, PostScript, PPML, LCDS, 
IPDS, VIPP or PDF format. This print input is passed on to the 
system through a network connection. The DocuSP software 
performs the necessary data conversion, creating an electronic 
file which is stored temporarily in a print queue on the DocuSP 
controller. This electronic image is then passed directly on to the 
printer for production.

The DocuTech 180 prints up to 180 prints per minute using 8.5 x 
11 inch/A4 (216 x 279 mm) stock.

The DocuTech 155 prints up to 155 prints per minute using 8.5 x 
11 inch/A4 (216 x 279 mm) stock.

The DocuTech 128 prints up to 128 prints per minute using 8.5 x 
11 inch/A4 (216 x 279 mm) stock.

NOTE:  The DocuTech HLC prints in black and white plus one 
highlight color.

NOTE:  Prints per minute vary, depending on paper size, for all 
printers.
