Introduction

This guide describes how to solve some specific problems that may occur when you are using the Xerox DocuPrint 96/4635/ 180/2000 Series NPS/IPS.

NOTE: You may be using the DocuPrint NPS/IPS software extension on a DocuPrint 2000 EPS system. The 2000 Series printer models are the 100, 135, 155, and 180. These printers are comparable in capabilities to the DocuPrint NPS/IPS models 96, 4635, and 180.

About this guide

This guide is designed for Xerox DocuPrint 96/4635/180/2000 Series NPS/IPS operators whose job consists of the routine operation of one of these systems.

Users should have an understanding of printer controller operations.

Before using this guide, become familiar with its contents and conventions.

This section lists the contents of this guide:

•Chapter 1, “Calling for service,” describes the information to have on hand when calling for support service, and provides information on using the Sixth Sense Technology.

•Chapter 2, “Fault masking,” describes how the Model 96/ 4635/180 NPS/IPS masks a problem so that the job will continue to print.

•Chapter 3, “Troubleshooting Xerox Client Software installation,” provides solutions to common problems with software installation.

•Bold: Within procedures, text and numbers that you enter are shown in bold (for example, enter privilege operator).

•The word “enter” within procedures: The two-step process of keying in data and pressing <ENTER> (for example, enter y).

•Italics: Document and library names are shown in italics (for example, the Xerox DocuPrint NPS/IPS Guide to Managing Print Jobs).

•Quotation marks: 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>).

xvi	Troubleshooting Guide

1.Calling for service

Before calling your customer service support center, make sure you have read this chapter and have tried the corrective actions described here. If the problem persists, gather the necessary information and call the customer support center.

Information to have on hand when calling for service

To report hardware or software problems in the United States, call the following number:

1-800-822-2979

For customers outside the United States, call your local service representative.

Before calling, make note of the following:

•Status code numbers and messages that appear on the controller screen and the printer console

•Indicator lights that are lit

•Name of your printer: DocuPrint 96 or 4635 or 180 or 2000 Series NPS/IPS

•Serial number for your printing system (located on the frame behind the narrow door to the far left, at the front of the printer)

•Problems you are having with the system.

Additional information you may wish to note prior to calling includes:

•An explanation of how output differs from what was expected.

•An assessment of whether the symptoms follow a pattern or occur randomly.

•A list of special conditions that may be related to the problems:

–New applications

–Changes made to the software

Troubleshooting Guide

1-1

Calling for service

–Recent service performed

–Previous conditions under which the application has printed properly.

Give this information to a customer service representative, who will discuss the information and give you an estimated time of arrival or assist you over the phone to resolve the problem.

Enabling and disabling the modem for remote service

Your system may be set up to use Sixth Sense Technology—a remote communication capability. Sixth Sense Technology is a suite of tools that allow service personnel to connect with a system and evaluate its performance. The service representative can troubleshoot problems remotely, transfer, apply, and remove patches remotely, and, if an on-site call is required, arrive with the solution to fix the problem.

An external modem allows your system to be accessed by remote service technicians.

You may be instructed to enable the modem so that the technician can dial into your system. Follow this procedure:

1.Stop all printing and queueing during the remote service session.

2.Follow the instructions of your service representative to enable the modem.

3.When the remote service session is complete, disable the modem.

4.Resume printing and queueing.

Refer to the Guide to Configuring and Managing the System, “Using utility commands” chapter, for more information on the commands used for remote service.

If security is a concern, you can turn off the modem, or you can physically disconnect the cable from the system when it is not being used.

CAUTION

Depending on the commands used by the technician, the printer may start up during the remote service session. You should not attempt to operate the system or perform any tasks at the printer while remote service is in process.

1-2	Troubleshooting Guide

2.Fault masking

This chapter describes the behavior of the 96/4635/180 NPS/IPS while printing with fault conditions.

The DocuPrint 96, 4635, and 180 NPS/IPS enable you to continue printing while certain faults or conditions exist in parts of the printer that are not currently in use. Such faults or conditions are said to be masked. An example of a masked fault condition is when feeder tray 1 is in use and feeder tray 2 is jammed, or stacker bin B is full.

When there is a masked fault or condition, the Hint icon (a light yellow circle with an asterisk inside) appears on the printer console and the goes on. A message, preceded by an asterisk, also appears in line 3 of the message area of the printer console. To display the area containing the masked fault, touch the Fault List Icon (shown below) on the printer console. The Fault List Icon appears.

Figure 2-1. Fault List icon

Troubleshooting Guide

2-1

Fault masking

Figure 2-2. Fault List screen

The Fault List screen displays any outstanding fault codes and shows a mimic of the printer; the area containing the masked fault is highlighted in light yellow. For greatest printer productivity, clear any masked faults at your earliest opportunity.

When the printer stops because of a fault, display the Fault List screen after clearing the fault to see if there are any masked faults. Clear these masked faults before continuing with the print job.

When there is a fault that cannot be masked and therefore causes the printer to stop, the Fault icon (a dark yellow triangle with an exclamation point inside) appears on the printer console and the Attention light flashes. The Fault screen appears on the printer console, highlighting (in dark yellow) the area(s) of the printer containing the fault and giving instructions for clearing the fault.

If a fault exists in the system at the time that a masked fault occurs, the printer console displays only the Fault icon. The remaining masked fault condition messages still display in the message area of the printer console.

2-2	Troubleshooting Guide

3.Troubleshooting Xerox Client Software installation

Xerox Client Software is downloaded from the printer controller to a network client workstation to enable a print command. Refer to the Guide to Submitting Jobs from the Client for more information.

If you are unable to install the Xerox Client Software, or if you install it and all requests submitted fail, try the following:

•Make sure the Xerox Client print command does not conflict with the local print command on the client system. To verify this, at the prompt (or on a new shell window prompt, for Sun clients), enter print. You should see the usage message for the Xerox Client print command.

If not, make sure that the environment variable path includes the subdirectory /usr/xerox/nps/client/bin and /usr/bin before the subdirectory containing the local print command. Also, resolve any print command aliases that might be set in the.cshrc file.

If you see the message “Server or Directory Unreachable” after executing a print command, perform the following steps:

1.If the printer controller software is newly installed, verify that queuing has started at the printer controller.

2.At the client, verify the host file exists and contains the printer controller name and TCP/IP address.

3.Verify the network connections between the printer controller and the client. Enter ping <Printer Controller name>; if that fails, enter ping <Printer Controller TCP/ IP address>. Verify that the TCP/IP address of the printer controller is the same as the one in the host file on the client.

4.Check for hardware problems.
