THE PRINT LINE BUS (PLB) PRODUCT OVERVIEW
Page 2-36 Xerox 495 Continuous Feed Duplex Printer Operator Guide
It doesn’t matter which PLB box in the print line segment provides the
power for the PLB, however, each print line segment must have only one
source of power.
The RS232 connection is used by support personnel to maintain the PLB
box. It is also used by the printers to carry communications data.
Characteristics
The maximum length of PLB cable between the first PLB box and the last
is of 100 metres (330 feet).
Up to 10 PLB boxes can be networked on the PLB.
Segmentation
The segmentation of the print line is possible through the PLB.
Segmentation is the ability to assemble devices in a number of ways to
form the print line required. Each device available in the print room is
connected to its PLB box. All PLB boxes are linked together.
The idea of segmentation is to allow you to define as many print lines as
you require, according to the devices available. These print line
definitions can then be recalled at any time. See "Defining a paper path"
on page 7-21.
Each print line has to be defined under a separate name. For example:
• cutter line 1
• folder line 2
Note: You should name each print line clearly enough to be able to
recognize it easily. It may be useful to label each device so as to be sure
that all devices required by a defined print line are suitably prepared for
the job. For example if the unwinder defined by the print line is not ready,
it will show the status not ready and no work will be produced.
