Laser safety
!Warning: Adjustments, use of controls, or performance of
procedures other than those specified herein may result in
hazardous light exposure.
The Xerox DocuPrint printers are certified to comply with the
performance standards of the U.S. Department of Health, Education,
and Welfare for Class 1 laser products. Class 1 laser products do not
emit hazardous radiation. The DocuPrint printers do not emit
hazardous radiation because the laser beam is completely enclosed
during all modes of customer operation.
The laser danger labels on the system are for Xerox service
representatives and are on or near panels or shields that must be
removed with a tool. DO NOT REMOVE LABELED PANELS OR
PANELS NEAR LABELS. ONLY XEROX SERVICE
REPRESENTATIVES HAVE ACCESS TO THESE PANELS.
This label is inside the left door, on the machine frame just above the
directions for clearing a jam in area 4.
Ozone information
This product produces ozone during normal operation. The amount
of ozone produced depends on copy volume. Ozone is heavier than
air. The environmental parameters specified in the Xerox installation
instructions ensure that concentration levels are within safe limits. If
you need additional information concerning ozone, call 1-800-828-
6571 to request the Xerox publication 600P83222, OZONE.
Operation safety
Your Xerox equipment and supplies have been designed and tested
to meet strict safety requirements. They have been approved by
safety agencies, and they comply with environmental standards.
Please observe the following precautions to ensure your continued
safety.
•Always connect equipment to a properly grounded electrical
outlet. If in doubt, have the outlet checked by a qualified
electrician.

!Warning: Improper connection of the equipment grounding
conductor may result in risk of electrical shock.
•Never use a ground adapter plug to connect equipment to an
electrical outlet that lacks a ground connection terminal.
•Always place equipment on a solid support surface with
adequate strength for its weight.
•Always use materials and supplies specifically designed for
your Xerox equipment. Use of unsuitable materials may result
in poor performance and may create a hazardous situation.
•Never move either the printer or the Printer Controller without
first contacting Xerox for approval.
•Never attempt any maintenance that is not specifically
described in this documentation.
•Never remove any covers or guards that are fastened with
screws. There are no operator-serviceable areas within these
covers.
•Never override electrical or mechanical interlocks.
•Never use supplies or cleaning materials for other than their
intended purposes. Keep all materials out of the reach of
children.
•Never operate the equipment if you notice unusual noises or
odors. Disconnect the power cord from the electrical outlet and
call service to correct the problem.
If you need any additional safety information concerning the
equipment or materials Xerox supplies, call Xerox Product Safety at
the following toll-free number in the United States:
1-800-828-6571
For customers outside the United States, contatct your local Xerox
operating company.

Introduction
The Xerox DocuPrint Network Printing Series Guide to Using PDL
describes how the PostScript, HP PCL 5, and VIPP (formerly XGF)
page description languages (PDLs) are implemented on the Xerox
DocuPrint NPS printers.
About this guide
This document is for users who will be submitting PostScript, HP
PCL 5, Decomposition Service, and VIPP jobs to the DocuPrint
printers. These users should be familiar with the applications they are
using to generate print jobs. This document is also for PostScript, HP
PCL 5, and VIPP programmers who will be creating applications
since it defines the features that are not supported for each PDL. It is
assumed that these programmers have a working knowledge of the
language they are working in. For specific reference information,
refer to the “Related information”section in this guide.
Before using this guide, become familiar with its contents and
conventions.
Contents
This section lists the contents of this guide:
•Chapter 1, “PCL 5,”provides information about how to use PCL
5 with your DocuPrint printer.
•Chapter 2, “PostScript,”contains the information you need to
use PostScript with your DocuPrint printer.
•Chapter 3, “VIPP,”provides instructions for using Variable Data
Intelligent PostScript PrintWare (formerly XGF) with your
DocuPrint.
Conventions
This document uses the following conventions:
•All caps and angle brackets—Within procedures, the names of
keys are shown in all caps within angle brackets (for example,
press <RETURN>).
•Angle brackets—Variable information, or the position of a
specified argument in the command syntax, appears in angle
brackets (for example, List Fonts <Pattern>).

INTRODUCTION
x XEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES
•Bold—Within procedures, text and numbers that you enter are
shown in bold (for example, enter privilege operator).
•“Enter”—Within procedures, the two-step process of keying in
data and pressing <RETURN> <ENTER> (for example,
enter y).
•Italics—Document and library names are shown in italics (for
example, the Xerox DocuPrint Publishing Series Guide to
Performing Routine Maintenance).
•Quotes—Keywords you can enter as arguments appear in
quotes (for example, “USLetter”).
•Vertical bars—Alternatives to specified arguments are
separated by vertical bars (for example, Set Time <Time |
Remote Host Name | IP Address>).
Note: Notes are hints that help you perform a task or understand
the text.
Caution: Cautions alert you to an action that could damage
hardware or software.
!Warning: Warnings alert you to conditions that may affect the
safety of people.
