overview

The Xerox DocuPrint 180 Laser Printing System (LPS) is a versatile,
high-performance printing system that processes and prints data
from a variety of sources. It enables host mainframe computers and
network-connected devices (such as workstations and graphic
scanners) to produce publications and other documents,
incorporating graphics, forms, logos, signatures, and a variety of
fonts.

With the Xerox DocuPrint 180 LPS, management information
systems (MIS) and data processing (DP) environments have a high­performance printer in which built-in intelligence eliminates the need
for the host computer to store and manage forms, fonts, and other
document resources.

Data is printed at a rate of up to 180 pages per minute (206 with the
optional Paper Feeding Enhancement Kit installed). A variety of
fonts ranging in size from 3 points to 36 points, in all four orientations
(portrait, inverse portrait, landscape, inverse landscape), and many
publishing typefaces are available to meet your printing require­ments. In addition to the standard set of fonts that is delivered with
the DocuPrint 180 LPS, special or customized fonts can be
developed by the Xerox Font Center. Your sales representative will
provide you with further information.

The following material is presented in this chapter:

• Hardware and software components

components:

Figure 1-1 shows the Xerox DocuPrint 180 LPS.

Figure 1-1. Xerox DocuPrint 180 Laser Printing System

1 System controller
2 Printer

The system controller is a minicomputer which manages the
processing of input data; processes operator commands; provides
for the entry and compiling of form, print, and job description files;
executes job processing commands; and manages low-level control
of the printer.

Your Xerox DocuPrint 180 LPS has a PC user interface (PC UI) that
enables you to start and monitor print jobs. In figure 1-1, the PC UI
is shown on top of the system controller.

The printer contains the mechanics and electronics involved in the
imaging and paper handling processes. Touch screen control on the
printer control console allows you to easily monitor and control printer
functions. Jam clearance areas and instructions are clearly
displayed with color graphics.

BASIC CONCEPTS

System controller

The system controller contains the input subsystem and the control
subsystem electronics.

The input subsystem provides interfacing capability (online, offline,
and Dynamic Document Interface (for DEC, PC, MAC, and UNIX
LAN connectivity) for a variety of input sources (host, magnetic tape,
workstations, and graphic scanners).

Note: Your quarter-inch cartridge tape and floppy disk drives are

not input sources for print jobs (refer to“Xerox DocuPrint 180 LPS
hardware components”).

The control subsystem performs all data handling, formatting,
buffering, and operational control of the system. It also provides
operator control through the DocuPrint 180 LPS PC User Interface
(UI). Refer to the “Xerox DocuPrint 180 LPS hardware components”
chapter for more information on system controller components and
these subsystems.

DocuPrint 180 LPS interface

The following DocuPrint 180 LPS interfaces are available to connect
a variety of input sources to the DocuPrint 180 LPS:

Offline interface The offline interface permits input from a computer-prepared

magnetic tape which is loaded onto the magnetic tape drive. The 9­track and 18/36-track magnetic tape drives are the optional offline
interfaces available for the Xerox DocuPrint 180 LPS. Refer to the
“Xerox DocuPrint 180 LPS hardware components” chapter for more
information.

Online interface The online interface permits input from a channel-attached host

computer.

DDI interface The Dynamic Docum ent Interface (DDI) enables commu nication

between a Xerox DocuPrint 180 LPS and network via a shared disk
mechanism over a SCSI bus. Refer to the Xerox Dynamic Document
Interface Operator Guide for information regarding the DDI.

DocuPrint 180 LPS system disk storage and memory

The system di sks stor e th e operat ing s ystem soft ware (OSS) as well
as the system resources (fonts, forms, and graphics) that are to be

Printer

BASIC CONCEPTS

The printer contains the imaging, xerographic, and output
subsystems.

Imaging subsystem

The imaging subsystem accepts a formatted page of data from the
system controller (forms and graphics have already been merged) for
the xerographic process.

Xerographic subsystem

One of the important keys to DocuPrint 180 LPS print quality lies in
the xerographic process itself. The print image produced by the dry
ink is very dark to create more contrast between the printing and the
page, making images easier to read.

The following steps describe the xerographic process:

Step 1. A band full of video data (1s and 0s) is transferred from the band

buffer to the laser scanner.

Step 2. The laser beam moves ac ross the surface of the photorece ptor belt

based on the value of the incoming bit (1 or 0), producing a latent
image.

In this step, a charge is applied to the surface of the photoreceptor
belt. The surface is discharged when it is exposed to the laser beam,
thus creating a pattern of dots corresponding to the page that is to be
printed.

Step 3. The photoreceptor belt is then exposed to dry ink. The dry ink clings

to the pattern of dots corresponding to the page that is to be printed.

Step 4. A sheet of paper traveling along the paper path is brought into

contact with the surface of the photoreceptor belt. The dry ink is then
transferred from the photoreceptor belt onto the paper.

Step 5. The paper carrying the pattern of dots passes through a fusing

mechanism that permanently affixes the dry ink to the paper.

Step 6. The finished page is deposited in the output tray or bin. The data

from that page is erased from memory. The photoreceptor belt is
then cleaned and prepared for the next page.

Resolution A n DocuPrint 180 LPS imaging system converts a character from

digitized form into a printed image composed of tiny dots. These dots
are so small and close together that they appear to form solid black
areas. Image clarity is determined largely by the resolution or the
number of dots per inch printed. Within the Xerox DocuPrint 180 LPS
Reference Set, the terms spots, dots, and pixels are used
interchangeably.

The Xerox DocuPrint 180 LPS accepts 300 dots per inch (dpi) print
data and images and electronically modifies them to produce 600 dpi
print resolution. 600 dpi input print data is not accepted by the Xerox
DocuPrint 180 LPS for printing. References to 300 dpi or 600 dpi
apply to both coordinate axes (300 by 300 dpi or 600 by 600 dpi).

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 2-3

BASIC CONCEPTS

Output subsystem

The output subsystem provides paper stacking, report collating, and
sample print capabilit ies .

DocuPrint 180 LPS production process overview

The process of producing a job on an DocuPrint 180 LPS can be
broken down into three distinct phases: input, special processing,
and output. Figure
2-2, illustrates these three phases below.

Figure 2-2. Basic processing flow

A description of each phase is described in the input section that
follows.

Sources of input for the DocuPrint 180 LPS

The input phase of job production begins with the collecting and
inputting of data using one of the following sources:

Several data input methods are available, as shown in figure 2-3

Peripheral Cabinet

(9-track,18/36-track

tape drives)

Online The channel-attached host computer input is received by the

DocuPrint 180 LPS online interface. In an online environment, the
system controller is physically wired to the host computer. The host

computer “thinks” it is communicating with an IBM 3211 line printer
and an IBM 3811 printing system controller, or an IBM 4245 line
printer.

DDI interface The Dynamic Docum ent Interface (DDI) enables commu nication

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 2-5

BASIC CONCEPTS

Types of data

Data is created at one of the above sources and transmitted to the

DocuPrint 180 LPS. As mentioned previously (refer to “Xerox
DocuPrint 180 LPS overview”), the system controller rece iv es the
incoming data using one of the interfaces for processing. If the input
is print data, a stream of data is sent to the printer for imaging. If the
input is nonprint data, it is stored on the system disks.

The following types of data can be printed by an DocuPrint 180 LPS:

• Variable data

• Fixed (forms) data

• Graphic data (usually merged with variable data or form data).

Variable data Variable data changes from page to page; for example, the text in this

document or the numbers in a financial report.

Fixed data Fixed (forms) data (FRM file) remains constant from page to page

(for example, letterheads and column headings). Forms data usually
refers to information found on preprinted forms or overlays.

Note: A host-resident forms design software package, such as
HFDL, is required for form generation at a host.

Any form suitable for computer printout can be described and
entered into system storage. Once stored on the system, a form can
be activated by referencing the form’s name in the job source library
(JSL) file or job descriptor entry (JDE).

All Xerox laser printing systems have as a standard feature a line
editor utility for the creation and modification of program source files
(FSL and JSL extension files). Refer to

Operations Reference

LPS Editor.
Forms are entered into the system as data using the DocuPrint 180

LPS Editor. They are described using forms description language
(FDL) commands to design the form for variable data. These
commands create what is referred to as a forms source library (FSL)
file which, when compiled, becomes an FRM file. Refer to

Forms Creation Guide

forms.

Graphic data Graphic data (IMG file) refers to digitized images (both line art and

continuous tone images) that are to be merged with variable or forms
data. Sources of graphic data include (but are not limited to): (1)
graphic data generated by XPPI/XDGI host-resident software, and
(2) scanned images from the Xerox 7650 Pro Imager (using XPIW).

Special processing

BASIC CONCEPTS

Special processing features distinguish the Xerox LPS from an
impact printer. By using commands such as RFEED, ROFFSET,
and RPAGE you can specify that certain logical functions including:
switching paper trays, offsetting certain pages or logically
repositioning a page, be performed during the printing process.
Refer to the
information on these command functions.

DJDE Dynamic Job Descriptor Entry (DJDE) command enables you to

modify the printing environment dynamically. These commands are
inserted into the input data stream to modify command
characteristics of the existing JDE. DJDEs can take effect on a
report-to-report, page-to-page, and record-to-record basis. Refer to
the

Xerox DocuPrint 180 LPS PDL Reference

CME A Copy Modification Entry (CME) command enables you to replace

certain parts of a report with predefined static data on selected
copies or to specify font changes within the variable data. Refer to
the

Xerox DocuPrint 180 LPS PDL Reference

for more information.

for more information.

for more

Output

The final production phase is output. The Xerox DocuPrint 180 LPS
provides powerful finishing and disbursement features. You can
have a true cover-to-cover printing process on any job. This means
that an inventory stock report job could have:

• Blue card stock front cover, with the title in a 24-point bold font

• Forty-nine pages of equipment inventory, with the last page

designed to summarize totals

• Thirty-seven pages of equipment description, with pricing

information remo ved and a shaded grid filling all page c olum ns

• A matching blue card stock back cover printed on the reverse

side with “END OF REPORT” in a 14-point bold font.

Each copy of the inventory report can be offset in a stacker bin (no
offsetting in the sample tray) for easy identification, with a routing
sheet on top of each offset stack which contains such information as
“Jones and Smith Supplies, Inc.” This particular feature is useful
when individual copies must be separated for binding or distribution
to different groups. By adding the optional bypass transport and a
third-party finisher to your Xerox DocuPrint 180 LPS, you expand
your finishing choices for your report to include options such as
making it into a booklet and shrink wrapping it.

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 2-7

BASIC CONCEPTS

Job source library (JSL) files

Print description language (PDL) commands are used to describe the
data layout and provide instructions for data placement on a page
with or without an FDL-created form. The JSL file contains PDL
statements defining the format of the input, processing requirements,
and the format of printed output. When the JSL file is compiled, it is
referred to as a job descriptor library (JDL) file and is referenced for
printing a job.

Within a JDL file, there may be one or more unique definitions for
different processing features, output formats, and tape formats.
Each set of unique definitions represents a job and is called a JDE or
a job.

A JDL (compiled JSL) file containing printing instructions for the
DocuPrint 180 LPS is required to print any job on any configuration.
Many specialized functions can be accomplished with PDL statement
comm a n ds. Refer to the
for specif ics

Several basic JSL files are provided with the OSS; for example,
ONLINE.JSL is provided for printing online jobs, a XEROX.JSL is
provided for printing magnetic tape jobs, and so on. To meet specific
application needs, any OSS-supplied JSL can be copied and

modified. All Xerox LPS’s have as a standard feature the LPS Editor
utility for the creation and modification of program source files (FSL
and JSL extension files).

Fonts

BASIC CONCEPTS

A font is a character set which has a unique typestyle, type size, and
orientation. Both fixed and proportionally spaced fonts are available
for use on an LPS. Each font character occupies an area called a
character cell. All character cells in a fixed font are the same width,
while character cells in a proportional font vary in width, as shown in
figure 2-4.

Figure 2-4. Character spacing

Because the length of a line printed with a proportional font is
relatively unpredictable, fixed fonts are used for variable data on a
report to avoid overprinting of forms by variable data.

Proportional fonts are normally used for forms data, such as, titles,
headings, and so on. A business letter is an example of the use of
proportional fonts for variable data. The difference in line length is
illustrated in figure 2-5.

Figure 2-5. Character spacing examples

Fonts are available in various typefaces (such as, OCR and Titan),
sizes, styles (such as, serif and sans serif), and weights (such as,
medium and bold). The
lists the standard fixed and proportional fonts.

In addition to typeface, style, and size, a font can be defined by its
orientation:

4. 4Xerox DocuPrint 180 LPS

This chapter describes the software components associated with the
Xerox DocuPrint 180 Laser Printing System (LPS). The major topics
are as follows:

• DocuPrint 180 LPS operating system

• Operating System Software (OSS) functional description

• Optional host-resident software packages.

DocuPrint 180 LPS operating system

The Xerox DocuPrint 180 LPS System Software consists of the
Xerox OSS, System User Interface (UI) Software, User Interface
Dialog, and the Printer Software. The OSS is the primary software;
however, each software type working in conjunction controls and
monitors the operation of your Xerox DocuPrint 180 LPS.

software

components

The DocuPrint 180 LPS OSS, like any other operating system, is a
set of programs which allow the printing system to manage its own
resources. Xerox distributes new versions of the Xerox DocuPrint
180 LPS OSS on a quarter-inch cartridge tape. The OSS tape
contains:

• New system files

• A system generation processor program that is used to load the

new system files onto the system disks and configure them for
a particular system

• A concatenated version of the system files and system

generation processor which is used for performing an online
system generation (wherein the processor and files are
downloaded to the printing system from a host computer)

• Patch files which are used to modify the new system files for

optimal performance.

Refer to the “System software functional description” chapter for
more details on OSS contents.

The process by which the OSS is installed, upgraded, or modified is
called system generation or sysgen. There are three types of
sysgens that can be performed: mini, update, or full.

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 4-1

XEROX DOCUPRINT 180 LPS SOFTWARE COMPONENTS

Mini sysgen In a mini sysgen, an existing operating system is modified in a way

that does not require new system file input or patching. For example,
an existing feature is deactivated or reactivated, or a specification is
changed that is independent of the operating system files.

Update sysgen In an update sysgen, an existing operating system is upgraded to

include new featur es or i s repla ced with a new version of the syst em.
During this process, some or all of the existing system files on the

system disks are replaced with new files; user files are not affected.

Full sysgen In a full sysgen, a new operating system is built on empty system

disks; that is, new or used disks that have been cleared and
formatted prior to sysgen.

Complete instructions for each of these sysgens are contained in the

Xerox DocuPrint 180 LPS System Generation Guide

The UI Software consists of two 3.5-inch floppy diskettes (one
supports the system UI Software, and one supports the UI Dialog).
The Printer Software also consists of several 3.5-inch floppy

diskettes. Refer to the “System software functional description”
chapter for further information on the System UI Software, UI Dialog,
and Printer Software.

.

Operating System Software functional description

The DocuPrint 180 LPS OSS, or system controller, runs both
background and foreground processing. All Xerox LPS systems are
run by basically the same software. The OSS is delivered for
installation and sysgen on quarter-inch cartridge tapes. The major
utilities or “tasks” run by the system controller are shown in their
hierarchical relationships in the chart below.

Figure 4-1 illustrates the hierarchy of the major DocuPrint 180 LPS
processing tasks. Following the figure is an overview of each task.

Operating system executive task The OSEXEC task is always runnin g. It interfaces wit h the DocuPrint

180 LPS hardware and logs hardware errors. In addition, it queues
devices, manages resources, establishes priority for software tasks,
and schedules processing.

File control program The F CP or FMS task manages disk resou rces. It manages and

allocates all disk space, creates all disk files, and accesses disk files.

Operator communication subsy stem The OCS task acts as an interface between the operator and

software tasks by receiving input from and displaying messages to
the operator. OCS also interfaces between system tasks.

Diagnostic tasks The OSDS runs either under the OSEXEC task or from offline

sources. It controls the processing for the PROBLEM command.
Diagnostic support is also provided to your service technician by the
stand-alone field engineering software (SAFES) task.

System utilities The DocuPrint 180 LPS has many utility programs which run under

the OSEXEC task that pr ov ide ma intenance servi ce s such a s:
backing up the system (DSR); tracki ng the unusable sectors on disks
(FCHECK); assigning a maximum size to the working print file
(REALLOCATE); eliminating wasted space on the disks
(COMPRESS); and making used space available again (PURGE).

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 4-3

XEROX DOCUPRINT 180 LPS SOFTWARE COMPONENTS

Editor task The E ditor task creates and mod ifies disk files. When you save a

work file, it stores the contents permanently on the disk. It sends files
to print; sends FSL and JSL files to be compiled; directs CMD files to
execute; and manipulates temporary (TMP), miscellaneous (MSC),
patch (PCH), and data (DAT) files.

Font Editor task The Font Editor task creates and modifies font files. The font files are

stored permanently on the disk when you save them.

Input task The input task reads in print job data, creates a job control block file,

and delivers job messages to the operator. Then the input task
unpacks and converts the data; selects and deletes blocks or
records; records any special processing instructions (for page
offsets, DJDE records, CMEs); and records the disk addresses of the
font, form, and image files used for the job. The result is a page
buffer, consisting of the variable data and print instructions for the
page, and the page log, consisting of tracking information used to
process the page.

Dynamic job descriptor task The DJD task compiles the Dynamic Job Descript or Entries (DJDE’s)

in the job stream. (The DJDE’s give the printer instructions for
printing based on the result of true/false tests of the data in the job
stream).

Output task The output task uses the page logs written by the input task to load

fonts in the font memory and variable data in the AIS. It causes paper
to feed from the indicated tray and manages report integrity with
multiple checks. In addition, Output manages delivery of the printed
pages to the correct bins and performs page recovery if necessary.

Print description language compiler The PDL task loads the PDL compiler and looks in the JSL library for

the file to be compiled. Then it analyzes the JSL statements and
creates the object module (the JDL file).

Forms description language compiler The FDL task loads the FDL compiler and looks in the FSL library for

the file to be compiled. Then it analyzes the FSL statements and
creates the object module (the FRM file).

Host interface processor task The HIP task controls DocuPrint 180 LPS communications with an

online host.

Report (RPT) task Works in connection with the Input task.

4-4 XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE

Printer Software

The Printer Software works in conjunction with the OSS (syst em
controller) to print your job. The system controller interprets the user
instructions contained in JDLs, DJDEs, and operator input, as well as
the data being printed on each page. The system controller, driven
by the OSS, sends this information to the printer. Once the
information reaches the printer, it is the Printer Software that
identifies the best way to carry out the task.

User Interface Software and User Dialog Software

As with the OSS and Printer Software, the System UI Software and
the User Interface Dialog interact together to control your PC UI.
Along with establishing and managing the communication betwe en
the PC UI and the printer, the User Interface Software displays the
objects on the UI screen and performs the actions input by the
operator, as specified within the UI Dialog.

5. 5Product differences/user
considerations

Your Xerox DocuPrint 180 Laser Printing System (LPS) has many
unique standard and optional features which distinguish it from other
Xerox LPS. Your Xerox DocuPrint 180 LPS is capable of running
most jobs created on other Xerox LPS, and can create jobs to print

on other LPS. The “DocuPrint 180 LPS compatibility and
comparison” section of this chapter points out the unique qualities of
your Xerox DocuPrint 180 LPS, and helps you evaluate whether your
Xerox DocuPrint 180 LPS running software version 3C2 is a suitable
backup printer for another Xerox LPS.

In order to ensure your jobs are created and produced with the
highest quality, there are many things you need to consider. The
“Xerox DocuPrint 180 LPS user considerations” section addresses
such items in the following major sect ions:

• DocuPrint 180 LPS compatibility and comparison

• Xerox DocuPrint 180 LPS user considerations.

DocuPrint 180 LPS compatibility and comparison

The tables in the sections that follow identify what you need to
consider when using your Xerox DocuPrint 180 LPS for printing jobs
created on other Xerox LPS with different software versions. They
also point out those features which are unique to your Xerox
DocuPrint 180 LPS. The tables are not designed to address
compatibility issues in an all-inclusive manner. Use them to make a
high-level check when you want to know if your Xerox DocuPrint 180
LPS will process and print a particular job.

Each table addresses a different area of consideration from PDL
commands to paper sizes and stocks. Often there is no need for any
further checking because the tables provide the answer. Other times
they show you where further investigation is needed, or suggest
specifically what you should check, either on your Xerox DocuPrint
180 LPS or in the print job. You may need to refer to another manual
in your Xerox DocuPrint 180 LPS r eference set for detailed guidance
on running a particular type of job or altering a job to make it
compatible with your Xerox DocuPrint 180 LPS.

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 5-1

PRODUCT DIFFERENCES/USER CONSIDERATIONS

In order to evaluate whether your Xerox DocuPrint 180 LPS running
software version 3C2 can be used as a suitable backup printer for a
print job created on another Xerox LPS running a different software
version, you must consider many factors. To help you begin the task
of determining if a job will run on your Xerox DocuPrint 180 LPS, use
this checklist for basic job compatibility:

1. Are font character sets required by the job loaded on the Xerox
DocuPrint 180 LPS?

2. Are forms required by the job loaded on the Xerox DocuPrint
180 LPS?

3. Is the allocated size of the print file on the Xerox DocuPrint 180
LPS appropriate for the print job?

4. Is the current forms default on the Xerox DocuPrint 180 LPS
appropriate for the print job?

5. Is the current graphics default on the Xerox DocuPrint 180 LPS
appropriate for the print job?

6. Is the current font default on the Xerox DocuPrint 180 LPS
appropriate for the print job?

7. Does the Xerox DocuPrint 180 LPS have sufficient memory for
the print job?

8. Does the print job require a finishing device?

9. Does the print job require a configured XPAF, HIP, or SDI
connection?

Checking JDL compatibility

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Job descriptor libraries (JDLs) are collections of compiled job
descriptions which are set up by the user. Many jobs may be
compiled on one LPS and run on another. Table 5-10 shows how

your Xerox DocuPrint 180 LPS handles JDL’s from other LPS.

Checking PDL compatibility

Print Description Language (PDL) commands define the format of
the input media, processing requirements, and the format of the
printed output. Each command has a set of parameters that can be
used to define a print job’s characteristics. Table 5-11 shows the
PDL command parameters that your Xerox DocuPrint 180 LPS does
not process. However, your Xerox DocuPrint 180 LPS processes
other parameters associated with the command.

PDL commands which the Xerox DocuPrint 180 LPS does not
process are indicated by an asterisk.

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Xerox DocuPrint 180 LPS user considerations

This section describes Xerox DocuPrint 180 LPS user
considerations.

Xerox DocuPrint 180 LPS edgema rki ng

To ensure consistency across all Xerox LPS printers, the coordinate
system used by all printers is identical. However, the area upon
which an actual image may appear is limited. Because of this, data
which starts near the edge of or off of the physical page may be lost.

Edgemarking is the placement of marks at or near the edge of the
physical page. To accommodate edgemarking, the system page
must be larger than the physical page.

The Xerox DocuPrint 180 LPS edgemarking capability could be
limited if the system page boundaries correspond to the sides of the
physical page of paper.

If any part of a form element or variable data line is positioned off the
leading edge of the system page (that is, the top edge of a
landscape-oriented page or the left edge of a portrait-oriented page),
the entire data element is not imaged. Refer to figure 5-1.

• If a line of variable text begins off the leading edge of the

system page, the entire line of text is not printed.

• If a ruled line begins off the leading edge of the system page,

the entire ruled line is not printed.

• A line running parallel to the leading edge needs to be

positioned at least half the line thickness inside the leading
edge of the system page in order to be printed. For example, a
bold line is 8 dots thick and it must, therefore, be positioned at
least 4 dots inside the leading edge of the system page.

• If any part of a signature or logo begins off the leading edge of

the system page, the entire signature or logo is not printed.

• One common cause of print elements accidentally beginning off

the system page is the improper use of the OUTPUT SHIFT
command. This command is used to shift the entire contents of
a page relative to the boundaries of the system page. When a
negative shift value is entered (as is often the case for the back
side of duplex pages), and that value exceeds the left margin,
no text elements will print. When using a negative value for the
OUTPUT SHIFT command, be sure that it is less than the value
of the left margin.

page.

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Figure 5-2 illustrates the edgemarking considerations for a
landscape page.

Figure 5-2. Edgemarking a landscape page

1 System page leading edge
2 Physical page leading edge
3 Within system page, data will edgemark
4 Off system page, data will not print.

To determine whether or not an item has fallen off the system page,
the following formulas may be used in determining the number of
dots (1/300 of an inch) which make up the area between the leading
edge of the system page and the leading edge of the physical page.
For 8.5- by 11 or 8.5- by 14-inch paper, the formula is:

Printer alignment in scan direction -1

For A4 paper, the formula is:

Printer alignment in scan direction +69

If any part of an item begins more than this number of dots before the
leading edge of the physical page, the item falls off the system page
and does not print.

Registration shift and skew

PRODUCT DIFFERENCES/USER CONSIDERATIONS

The registration of a printed image can appear shifted or skewed on
a page if the sheet of paper is misaligned as it enters the printer.
Because of the design of the DocuPrint 180 LPS feeder, the image
registration on each page can vary slightly both horizontally and
vertically by up to 0.65 mm. The image can also be slanted or
skewed slightly by 3.97 milliradians. (Figures 5-3 and 5-4 illustrate
landscape and portrait shift and skew.) Note that th e following figures
are the same specifications merely rotated to show portrait and
landscape orientations. The shift and skew variances described here
are within allowable specifications, but as this can affect the
registration of variable data in preprinted forms and the placement of
images close to the edge of the page, it is important to make
allowance for this condition.

Figure 5-3 illustrates the landscape orientation shift and skew.

Paper size

The following sections describe paper sizes.

Variable paper size Page dimensions up to the physical capacity of the feeder trays may

be selected. (The largest feeder tray physical capacity is 14 by 17
inch; the smallest is 7 by 10 inch with the optional Paper Feeding
Enhancement Kit installed). At system generation (sysgen), you can

select USLETTER, USLEGAL, or A4; or you can select “other” and
specify any paper size between the smallest and largest allowed (x
by y) in millimeters. 11- by 17-inch/297- by 432-mm jobs are not
supported, however, your Xerox DocuPrint 180 LPS handles 11- by
17-inch/297- by 432-mm IMG jobs.

The use of the PAPERSIZE command in PDL and the PAPER
command in FDL permits form compilation and job printing on a size
of paper other than the sysgened paper size and allows the
specification of nonstandard paper sizes for those jobs requiring
nonstandard paper

It is recommended that you sysgen to the largest size paper that you
commonly use. Smaller and less-used paper sizes should be
specified using PDL and FDL commands.

Virtual page size

Error messages

PRODUCT DIFFERENCES/USER CONSIDERATIONS

The Xerox DocuPrint 180 maxi mum imaging area (that is, the syste m
page) measures 14- by 17-inches.

The default virtual page size is identical to the physical page size. If
a virtual page size is user-defined, the virtual page is centered
relative to the physical page. A user-defined virtual page may not be
larger than the paper size value; larger dimensions are truncated.

If any part of a print line originates off the system page, the following
message is displayed:

OS6905 DATA ORIGIN OFF PAGE -- CHECK OUTPUT.
This message appears only once during a print job. It indicates a

print line origin problem within the form description or an excessive
SHIFT value. Refer to

Deletions

The Xerox DocuPrint 180 printer utilizes the newest xerographic
advancements, providing good solid black print quality and spot
control. However, in certain circumstances, there is a possibility t hat
toner from the photoreceptor may not completely transfer to a sheet
of paper before it is fused and sent to the output bin. This occurrence
is known as a deletion. Generally, deletions will result in a small area
of the printed page appearing lighter than the rest of the page. For
example, a few letters of a word may appear lighter than the rest of
the word.

To help reduce the occurrence of deletion, the Xerox DocuPrint 180
printer has been fitted with a four-segment transfer blade which
presses the paper onto the photoreceptor during toner transfer. This
blade is automatically activated based on the paper size setting in the
job descriptor and does not involve any operator interaction or loss of
productivity.

There are two different transfer blades: one for 60Hz systems and
one for 50Hz systems. Each blade can adjust to four paper size
lengths as follows:

• 60 Hz blade: 11-, 11.69-, 13-, and 14-inch (279-, 297-, 330-,

356-mm)

• 50 Hz blade: 10-, 11-, 11.69-, and 13-inch (254-, 279-, 297-,

330-mm).

XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE 5-23

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Thus, if you switch from 8.5- by 11-inch/216- by 279-mm to U.S. legal
(8.5- by 14-inch/216- by 356-mm), the 11-inch/279-mm segment is
utilized first, then the additional blade extension to 14-inch/356-mm
is activated automatically when the legal size paper is encountered.

Two points to note:

• For page lengths in between the preset blade lengths, there

may be some deletion on paper that extends past the blade.
The rate of occurrence of deletions varies widely, depending on
paper stock, and should be tested. Also, note that no deletion
will be noticed if no data is printed on the portion of paper that
extends past the blade.

If you frequently use non-standard size paper, a custom
transfer blade kit is available for installation on your printer. For
more information on the custom transfer assist blade, refer to
the

Xerox DocuPrint 180 LPS Operator Guide

.

• The activation of the blade is timed to place it on the lead edge

of the sheet of paper as it moves through the system. The
placement of the activation can vary with the actual speed of
paper. Therefore, performance may demonstrate some
deletions on the lead 0.25-inches/6-mm of the page. In
particular, solid black lines on the lead edge of the page should
be avoided if this is a major concern to you.

A consideration resulting from the very solid black characters that the
DocuPrint 180 LPS can print is that toner on the lead edge of the
paper may cause the sheet to stick to the fuser, due to the
consistency and solidness of the toner. In order to eliminate fuser
jams caused by this condition, the system uses a digital screen to
lighten automatically any solid areas printed in the first 0.25 inches/
6mm of the lead edge. If the solid areas are small, the amount of
screen is barely noticeable, if at all. However, with very large solid
black areas, the effect may not be acceptable. The system does
provide an override using the Lead Edge Screen window at the PC
UI, or the EDGE command entered at the command line. This
window or command allows you to enable or disable the lead edge
screen; however, overriding the screen in this manner is likely to
increase fuser jams.

For particular applications, it is recommended that you run test prints
both with and without the screen to ascertain which mode is most
appropriate for you.

For more information on the Lead Edge Screen window, refer to the

Print Darkness

Interpolation and scanned images

PRODUCT DIFFERENCES/USER CONSIDERATIONS

The Xerox DocuPrint 180 LPS provides you with capabilities for
tuning your output print quality to meet the particular needs of your
application. The Print Darkness window at the PC UI is a feature
which allows you to adjust darkness of printed characters and
images. Print darkness is a scale from 1 to 9, which either darkens
or lightens the image, as well as broadening or thinning the look of
various characters. The nominal setting is 5, which provides the
optimal mix of darkness and line thickness.

It is recommended that you test the Print Darkness feature to
determine the best setting for your site or application. For more
information on the Print Darkness window, re

The Xerox DocuPrint 180 LPS accepts 300 spi data and prints it
using a 600 spi dual beam raster output scanner (ROS). To convert
300 spi input data to 600 spi print output, the system uses an
interpolation algorithm to smooth lines and improve the quality of 300
spi fonts and line art.

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Switching paper size and feed modes

The Xerox DocuPrint 180 LPS system operates in a multiple-pitch
print mode: 8 pitch to 3 pitch.

The multi-pitch feature allows your Xerox DocuPrint 180 LPS to
adjust the pitch mode according to the width of the paper you are
using. Table 5-15 shows the relation between the pitch mode, the
maximum width of the paper being fed in a long edge feed mode, and
the page per minute (PPM) rate. Long edge feed mode means the
sheet is fed into the paper path with its long edge first.

7 pitch 9 inches/229 mm 180 PPM
8 pitch* 7.4 inches/188 mm 206 PPM
*8 pitch is enabled only with the optional Paper Feeding

Enhancement Kit installed.

For papers whose widths range from 8.66 to 9 inches, the Xerox
DocuPrint 180 prints with slightly reduced productivity at 180 pages
per minute, with seven-page images per photoreceptor revolution.
Productivity is slightly reduced because in order to maintain print
speed for papers of this size, the system must temporarily suspend
xerographic print quality checks. The Xerox DocuPrint 180 maintains
the highest print quality by periodically reducing printer output to
perform xerographic print quality checks. After a print quality check,
the system automatically resumes printing at full productivity.

5-26 XEROX DOCUPRINT 180 LASER PRINTING SYSTEM PRODUCT GUIDE

PRODUCT DIFFERENCES/USER CONSIDERATIONS

Cleaning time between pitch mode changes

Because the xerographic process places toner images on the
photoreceptor belt, it is necessary for the printer to clean the system
completely when switching to different modes. This cleaning process
ensures that unprinted toner from one pitch mode is not deposited on
sheets running in the other mode. This cleaning process requires

approximately 25-30 seconds, during which time the system “dead
cycles” before printing again. During this time, areas of the printer
are running, but paper is not fed through the system.

Specialized papers The Xerox DocuPrint 180 printer handles paper differently from the

9790 and other Xerox LPS. Paper sensors and the paper path are
not the same from one printing product to another. An application
running special papers on a 9790, for example, may yield slightly
different results when printed on the Xerox DocuPrint 180 LPS.
Therefore, it is recommended that you test applications that use
specialized papers to ensure that output is satisfactory.

Pay special attention to the following materials:

• Die cut paper (paper with windows or areas cut out) must be

tested to ensure that the sheet registers properly with paper
sensors.

• Multiple-thickness materials may cause stacking problems.

Such problems may be alleviated by using the Bin Limits
window or command to limit the number of sheets that can be
stacked in a bin.

• For information on the Bin Limits window and command, refer
