Resolution
The 4850/4890 NPS/IPS provides high print quality at 300 dpi
resolution. It can receive data at 240, 300, or 600 dpi. The
controller converts 240 and 600 to 300 dpi data.
The 92C NPS/IPS provides exceptional print quality at 600 dpi
resolution. It can receive data at 240, 300, or 600 dpi. The
controller can convert incoming data to 600 dpi for printing, or
can conv ert the data to 240 o r 30 0 dpi an d al lo w t he print en gine
to convert the pages to 600 dpi.

IPS
The entire DocuPrint NPS/IPS system includes the printer (also
known as an IOT or print engine), printer controller, printer
interface, and all appropriate software. “DocuPrint printer” or
“printer” refers to the base printer e ng ine (IOT) only, without the
printer controller and interface.

Xerox-supplied
printer controller
The printer controller includes a processor, DVD-ROM (or CD ROM) driv e , disk ette driv e, k e ybo ard, mo use, and a m onitor. The
printer controller accepts the print job fr om the clien t wo rkstation
or host, converts the files into page images, and sends the page
images to the printer. The user interface at the printer controller
allows you to perform tasks such as monitoring job status,
prioritizing jobs, and configuring the system.

Connectivity configurations
The printer interface cables provide high-speed data transport
and communication between the printer controller and the
printer.
The printer accepts data from the printer co ntroller and prints the
document according to the print options specified by the user.
The printer also provides optional paper stitching and stacking.
The NPS/IPS ca n process network PDL and IPDS jobs
concurrently.
To support the submission of jo bs from a variety of hosts,
configuration possibilities include:
• The same T ok en Ring or Ethernet connection can be used for
both IPDS and Postscript/PCL.
• Both a Token Ring card and an Ethernet card can reside in
the Sun workstation controller, with one being used for IPDS
and the other for PostScript/PCL.
• Bus and tag attach ment thro ugh the channe l interface can be
used for IPDS jobs from a channel-attached host; T ok en Ring
or Ethernet connection can be used for jobs submitted over
the network.
NPS/IPS concurrent printing
The Xerox NPS/IPS can receive a variety of data streams
including IPDS, PostScript Levels 1 and 2, PCL 5c, PCL 5e, TIFF,
and ASCII. The system automatically senses the type of job and
processes it appropriately.
When your system is printing IPDS jobs, it can accept network
PDL data streams in the background. When network PDL jobs
are printing, only one IPDS job can be queued.

System overview
Document Feeding and Finishing Architecture (DFA)
SNMP support
The Document Feeding and Finishing Architectu re (DFA) on the
NPS/IPS supports all third-party finishing devices currently
validated for the LCDS (J11) printers (DFA is not supported on
the 4850). The bypass transport option is required for in-line
finishing devices .
The system provides functionality to export the state of a printer
using the Simple Network Management Protocol (SNMP), thus
allowing printer management software to monitor and report on
the printer state.
SNMP is a standardized communications protocol for managing
arbitrary networked devices from different vendors, such as
workstations, servers, printers, or routers. The information to be
communicated is presented as variable name/value pairs,
defined in a set of standardized management information bases
(MIBs). The MIBs define the legal variables, their types, and
possibly a fixed set of values.
SNMP was designed to facilitate managing a heterogeneous set
of networked devices that communicate using TCP/IP.
Specifically, it addressed management of the network itself and
the network traffic betw een th ose devices. Over time, MIBs were
defined to expand the types of devices that could be managed
using SNMP. For example, MIBs were defined specific to
managing a wor kstation or a printer.
The system currently supports variables defined in the following
MIBs:
• MIB-II (RFC 1156)
This MIB defines the basic set of variables any device
running TCP/IP should make accessible . It includes, for a
particular device, variables for information such as a system
description, information about each of the network interfaces
present on the device, and information abou t all the IP
datagrams sent and received by the device.
1-4 System Overview Guide
System overview
• Host Resources MIB (RFC 1514)
This MIB defines variables useful in managing a “host”
system. In this context, a host is a computer that is directly
used by human beings and that communicates with other
similar computers attached through a network. The Host
Resources MIB includes information such as how long the
system has been up, descriptions of the processors and
attached storage devices, and possibly information about
software running on the host.
• Printer MIB (RFC 1759)
This MIB defines information useful in managing a printer. It
includes information about the physical status of the printer,
such as the number of input trays, the media loaded in them,
and the numbe r and types of marking en gines inclu ded in the
printer.
Most variab les in these MIBs a re supported in a standard w ay, as
described in the standard documentation, except that writing to
read/write variables is not supported. All variables are treated as
read-only. In all cases, the NPS/IPS SNMP implementation
supplies textual information only in English.
IPP support
Sixth Sense
The system supports the Internet Printing Protocol (IPP), which
allows you to:
• Add the printer to your PC directly as an Internet printer with
a URL, rather than indirectly as an lpr-connected local printer.
• Use an IPP client to access the printer. A limited subset of
IPP operations is supported; query the IPP client for details.
Sixth Sense is a unique suite of diagnostic tools that allows
Xerox customer service engineers, analysts, and consultants to
serve customers more effectively.
System Overview Guide 1-5
System overview
Sixth Sense is intended to automate and expedite the range of
service-related support functions. Sixth Sense is a tool that
enables Xerox to provide benchmark service support. Xerox
customers benefit from the ability to bring broader support to
focus more quickly.
For example, Sixth Sense can allow the Service Representative
to repeatedly "preview" the condition of the system prior to an
actual site visit. This may provide the ability to determine the
correct part or piece of information to have on hand when the site
visit is made.
Sixth Sense is a no-charge feature available to customers
through Xerox Service. The customer need only provide an
analog phone li ne for use by t he Sixth Sense modem connec tion.
For those cust omers una bl e to dedicate a ph one line to th e Sixth
Sense connection, three and five port phone share devices are
available for purchase.
To take advantage of Sixth Sense, the customer needs to:
Software license
• Request Sixth Sense enablement through Xerox Service
• Provide an analog phone line
• If necessary, purchase an optional phone share device.
More information abou t the Sixth Sen s e can be found in the
Troubleshooting Guide for your system.
In order to use the operating system software, the owner must
obtain a software license from Xerox. The license, which is a 20character text string, is entered at the printer controller.
Your Xerox service representative can obtain this license text
string for you and enter it when the printer is installed or when
the software is upgraded. Although your service representative
usually does this f or you, y ou are ab le to ente r yo ur license string
yourself from the NPS/IPS main window.
Until the license string is entered, your printer cannot print or
receive data. You can, however , perform all offline tasks, such as
setting up virtual printers.
For details on obtaining and entering the license string, refer to
the Guide to Configuring and Managing the System.

How highlight color is created
A document with highlight color contains one color plus black.
The color ma y be printed either as a solid col or or combin ed wit h
black. The NPS/IPS prints the highlight color by printing small
dots in a single pass with near-perfect registration. The following
methods are used to create various tints, shades and tones:
• Tints of black or the highlight color are created by printing
dots of black or color with white space between them, thus
producing a percentage value of the color. An example of this
is gray or pink.
• Shades are created by printing black dots next to dots of the
highlight color. An example of this is dark red.
• Tones are created by printing a combination of black dots,
color dots, and blank space. The result is a percentage value
of black and the highlight color. Dark red is made by mixing
dots of red and black. Gray-pink is made by mixing red dots,
black dots and some blank spa ce.
System overview
• The patterns of dots are known as screens. Screens are
defined in the printer controller software as a matrix of bits,
which correspond to printed dots. The screen defines which
dots in the matrix are black, which are highlight color, and
which are not printed.
How to convert full color to highlight color
The NPS/IPS provides a selection of black dry ink and ten color
dry inks:
1. Red
2. Green
3. Blue
4. Cyan
5. Magenta
6. Cardinal (red)
7. Royal (blue)
8. Ruby
9. Violet
10.Brown.
System Overview Guide 1-7
System overview
When the NPS/IP S receives a full-color document, the printer
software matches t he colors as closely a s possible . If y ou specify
a color in your document that the NPS/IPS cannot print, it is
printed either as a shade of gray or as an equivalent tone of
highlight color.
To control color conversion in your document, you can use the
map color option, also called “extraction color.” The map color
option is used to specify which color in the full color document
you want to print using the highlight color. Colors you do not
specify in the map color option print as shades of gray.
You can make the map color diff er fr om the highl ight color so that
red parts of a document are printed as green, or blue portions
are printed as red, and so forth.
The highlight color rendering algorithm enables you to specify
the qualities of a document that are the most important to
preserve. The highlight rendering attributes allow you to
distinguish between different colors, use preset color tables,
apply pictorial mapping for pictures, and apply presentation
mapping for other objects.
NOTE: To determine the RGB values of a specified highlight
color , vie w the system o ptions. When the Pictorial highlight colo r
rendering algorithm is used, the specified RGB value saturates
on the page. When the presentation algorithm is used, the RGB
value does not saturate on the page.
Color substitution
If the print document calls for a color that is not installed in the
printer, the printer controller acts according to the current color
substitution parameters.
The options for color substitution with the color mismatch action
are:
• Abort: Dele tes the job.
• UseLoadedColor: Uses the dry ink that is currently loaded
on the printer.
• RequestOperatorIntervention: Causes a job to be
ineligible for printing until the highlight color is changed.
You can specify these color substitution options at a client
workstation when sub mitting a job to the p rinter, or by specifying
the HightlightColorMismatchAction attribute in a virtual printer.
1-8 System Overview Guide
2. Printer controller overview
The printer controller manages print options, provides the user
interface, and runs system management and diagnostic
operations on demand. The following is an explanation of tasks
that enable the job to be printed:
• The printer controller detects which job protocol is being sent.
• Print option parameters are stored in the Job Pool Manager
(JPM) database, which maintains a database of all jobs. This
database contains a reference to the print data on the fixed
disk, as well as the print optio ns paramete rs for the prin t data.
The JPM responds to the printer controller commands for
deleting, hol ding, and prioritizing jobs.
• Print data is stored on the printer controller disk for queuing
and while printing.
• When the printer controller begins processing a job, it sends
the print data to the decomposer. The decomposer converts
the print data into a bitmap in the resolution appropriate to
the printing device.
The decomposer utilizes font data from font files stored on
the printer c ontroller disk or font information sent to the
printer controller with the print job.
• When processed da ta come s back from the decomposer, the
printer controller Device Driver transmits the print data and
print option parameters to the printer. Printing is then
initiated.
• After the job has been printed successfully, the print data file
is deleted from the disk. If an error inhibits job completion, the
printer controller manages the recovery and completion of
the job.
The system can manage the processing of multiple jobs and the
printing of another job simultaneously. When you are printing
IPDS jobs, the printer controller is able to queue multiple
PostScript and PCL jobs at the same time. When you are printing
PostScript and PCL jobs, you can send only one IPDS job.
