Precautions

Precautions

Always observe the following general precautions when installing and servicing the
E-800A:

1. Report any shipping damage.

If there is any evidence of shipping or handling damage to the E-800A packing boxes or
their contents, save the damaged boxes and parts, call the shipper immediately to file a
claim, and notify your authorized service/support center.

2. Never alter an existing network without permission.

The E-800A will probably be connected to an existing Local Area Network (LAN) based
on Ethernet hardware. The network is the link between the customer ’s computer, existing
laser printers, and other prepress equipment. Never disturb the LAN by breaking or
making a network connection, altering termination, installing or removing networking
hardware or software, or shutting down networked devices without the knowledge and
express permission of the system or network administrator or the shop supervisor.

3. Never assign an IP address in the E-800A Network Setup.

Only the network administrator should assign an IP address to a network device.
Assigning the E-800A an incorrect IP address may cause unpredictable errors on any or
all devices connected to the network.

4. Always disconnect power before opening the E-800A.

5. Handle the E-800A Control Panel display window with care.

The E-800A display window is made of glass. If the glass breaks and the liquid crystal
inside leaks out, avoid contact with it. If you do come in contact with the liquid crystal,
wash it off with soap and water immediately.

6. Avoid pressing the surface of the display window.

Applying pressure to the display window will cause it to change color.

7. Use a soft cloth moistened with isopropyl or ethyl alcohol to clean the surface of the
E-800A display window.

Other solvents, such as water, may damage the polarizer on the display window.

xiii

Preface

8. Use care when handling parts of the E-800A as some edges on the unit may be sharp. For
example, be careful when:

• Accessing the CD-ROM/ZIP drive (keep the drive door closed when not in use)

• Plugging in cables at the back of the unit

• Using the power switch to power on/off the unit

9. Follow standard ESD (electrostatic discharge) precautions while working on the internal
components of the E-800A.

Static is always a concern when servicing electronic devices. It is highly unlikely that the
area around the copier and the E-800A is static-free. Carpeting, leather-soled shoes,
synthetic clothing fibers, silks, and plastics may generate a static charge of more than
10,000 volts. Static discharge is capable of destroying the circuits etched in silicon
microchips, or dramatically shortening their life span. By observing standard precautions,
you may avoid extra service calls and save the cost of a new board.

When possible, work on a ground-connected antistatic mat. Wear an antistatic
grounding strap, grounded at the same place as the antistatic mat. If that is not possible:

• Attach a grounding strap to your wrist. Attach the other end to a good ground.

• When you unpack the E-800A from the carton for the first time, touch a metal area of

the copier to discharge the static on your body.

• Before you remove the E-800A side panel and before y ou handle internal components,

touch a metal part of the E-800A.

• Leave new electronic components inside their antistatic bags until you are ready to

install them. When you remove components from an antistatic bag, place them on a
grounded antistatic surface, component-side up.

• When you remove an electronic component, place it into an antistatic bag

immediately. Do not walk across a carpet or vinyl floor while carrying an unprotected
board.

10. Handle printed circuit boards by their opposing edges only, and avoid touching the
contacts on the edge of the board.

11. Never set a cup of coffee—or any liquid—on or near the E-800A or the copier.

xiv

Introduction

How the E-800A operates

The E-800A enables the customer to use a color copier as a printer and scanner. Users
can print to the E-800A from networked PCs running Microsoft Windows, from
networked Mac OS computers, and from networked UNIX workstations running
TCP/IP.

The E-800A custom-designed boards and system software are responsible for efficient
image processing and printing controls. The main functions of E-800A components and
software are described below.

The E-800A uses specialized circuit boards, the motherboard and the copier interface
board to process image data for printing and scanning images.

The motherboard includes a 500MHz CPU which controls the image data transfer to
and from the copier interface board and runs the interpreter. The interpreter rasterizes
the page description file and then compresses the image pattern into memory using
compression technology.

The interpreter outputs compressed raster data through the image frame buffer memory
to the E-800A copier interface board. The copier interface board decompr esses the image
data and sends it to the copier through the copier interface cable. The raster data supplied
to the laser in the copier charges the drum and renders the final image on paper at full
copier engine speed.

High-speed DIMMs (dual in-line memory modules) on the motherboard hold the image
data during printing. The E-800A is configured with 320MB of memory.

When Fiery Scan™ uses the copier as a scanner, the E-800A acquires RGB (red, green,
and blue) image data from the copier, stores it in memory, and transmits it to the
computer that requested the scan.

Installation sequence

Familiarize yourself with Chapters 2 and 3 of this guide before you attempt an
installation. The installation sequence described in this chapter is designed to make your
job as easy as possible. Installation problems are easier to avoid and diagnose if you
proceed from the component to the system level and verify functionality at each stage.
Figure 2-1 on page 2-2 outlines the recommended installation procedure for connecting
the E-800A to the copier.

Because the E-800A is a node on the customer’s computer network, make sure you
coordinate your scheduled installation with the network administrator at the customer
site. Refer the network administrator to the Configuration Guide for network setup
information.

Checking the customer site

2

Checking the customer site

Before you install the E-800A, check site conditions and inform the customer of any
installation requirements.

Copier model

❑ What copier model is installed?
❑ Is there space near the copier for the E-800A?

Make sure that there is space for the E-800A. You may need to move the copier out from
the wall for easier access to the connectors.

❑ Does the copier require service or adjustments?

Copy the copier color test page before you install the E-800A.
If the copied image indicates that the copier needs adjustment, inform the customer.

After getting approval, complete the copier service needed.

Power

❑ Is there a dedicated grounded electrical outlet near the copier for the E-800A?

Locate the grounded electrical outlet that will supply power to the E-800A. You should
not run the E-800A and the copier on the same circuit. Use a surge suppressor for the
E-800A.

• Do not use a 3-prong adapter in a 2-hole ungrounded outlet.

• Do not use an extension cord.

• Do not plug the E-800A into a circuit with heating or refrigeration equipment

(including water coolers).

• Do not plug the E-800A into a switchable wall outlet. This can result in the E-800A

being turned off accidentally.

Network

❑ What is the network cable and connection type?

• Unshielded twisted pair (10BaseT/100BaseT)

• Optional Token Ring (shielded twisted pair or unshielded twisted pair)?

❑ Is the network connection ready and tested for E-800A installation?

To verify that the network is functioning before you attach the E-800A:

• Ask the network administrator to print a document on a shared printer over the

network.

2-3

Preparing for Installation

2

• Ask the network administrator to verify the computer and network requirements as

specified in Getting Started.

System contact person

❑ Will the person responsible for the computers and the network be available at the time

set for installation? Get a name as a contact.

Setting customer expectations

If the site is ready, installation takes about one hour. The customer should be informed of
the following:

• Some nodes on the network may be unavailable for up to one hour.

• The copier may be unavailable for up to one hour.

• The network administrator needs to be available during the installation for network

connectivity.
Equipment downtime and impact on the network can be minimized if the network

administrator installs a network connector for the E-800A and confirms network
functionality with the connector in place before the date scheduled for the E-800A
installation.

• The network administrator should have a networked computer available during the

installation. The appropriate software should already be installed. Documentation for
the networked computer and the network operating software should be available.

• The network administrator should install the user software shipped with the E-800A

(user documentation is also included) onto networked PC and Mac OS computers
that will print to the E-800A.

NOTE: This guide covers E-800A hardware installation and service. It provides general

information on connecting the E-800A to the customer’s network. Network setup and
configuration information goes beyond the scope of this guide. For network setup and
configuration information, the network administrator should use the Configuration
Guide.

Checking E-800A internal connections

The most common causes of hardware problems are faulty and loose connections. Before
you conclude that any board or component has failed, remove, inspect, and reseat all
appropriate connections, and then verify that the problem still occurs.

TO CHECK BOARD AND CABLE CONNECTIONS

1. Before you touch any parts inside the E-800A, attach a grounding wrist strap. Touching
the metal part of the power supply case inside the E-800A also discharges static
electricity.

2. Position the E-800A so it is resting on its side and the internal components of the
E-800A are facing up.

3. Inspect the E-800A boards for secure insertion into the motherboard. Press down firmly
on each board to make sure it is securely installed.

Looking into the tray from the top, the standard board configuration includes the
following (from top to bottom):

Connector PCI1—IX UIB board
Connector PCI2—Empty
Connector AGP—AGP video board
Connector PCI3—Empty
Connector PCI4—Empty

4-8

Connector PCI5—Copier interface board
Connector PCI6—Empty
Connector SlotA1—Empty

4. Inspect ribbon cables to see if they are intact.

Faulty ribbon cables are easily overlooked. Check the contact point between the cable
and the connector to ensure that they have not separated. If a ribbon cable is suspect,
substitute it with a tested cable.

5. Make sure that all E-800A ribbon cables and power cables are seated on connectors. See
Figure 4-6 on page 4-9.

Cable connectors are keyed to fit only when properly oriented.

6. Check the front fan, back panel fan, CPU fan, and reset cable connections to the
motherboard.

7. After tightening connections, if one or more E-800A components are still not getting
power, see “Checking voltages” on page 4-40.

Replacing the motherboard

This section includes the procedures required to replace the E-800A motherboard. Spare
motherboards ship without memory, CPU, and the BIOS chip. The memory, CPU and
BIOS chip from the old board will need to be installed on the replacement motherboard.

TO REPLACE THE MOTHERBOARD

1. If you replaced the motherboard with a new boar d, r eplace the f ollo wing components on
the board:

• Memory (see page 4-30)

• CPU (see page 4-32)

• BIOS chip (see page 4-34)

2. Angle the motherboard so the back panel connectors on the motherboard fit into the
cutouts in the back of the tray. See Figure 4-18 on page 4-27.

3. Align the mounting holes on the edge of the motherboard (opposite the back panel
connectors) with the standoffs located in the base of the tray (see Figure 4-18 on
page 4-27).

4. Once the mounting holes in the motherboard are aligned over the stando ff s , gently push
the motherboard down to secure it to the tray.

5. Insert the 9 motherboard mounting screws to attach the motherboard to the tray but do
not tighten them completely (see Figure 4-17 on page 4-24 for screw locations).

6. Tighten the 9 motherboard mounting screws.

Do not overtighten the screws; doing so could damage traces on the motherboard.

7. Replace the board guide and secure it with two screws (see Figure 4-1 on page 4-2).

TO REPLACE BOARDS

1. Replace the following boards in the appropriate motherboard connectors:

• IX UIB board in the connector labeled PCI1

• AGP video board in the connector labeled AGP

• Copier interface board in the connector labeled PCI5

As you plug the board into the connector on the motherboard, make sure that the board
connector is properly aligned with the connector on the motherboard.

Motherboard jumpers and switches

The E-800A motherboard ships with jumpers installed on pins 1 and 2 of jumper area
JP9 and a jumper installed on J21. All other jumper areas do not have jumpers installed.
Switch S4 on the motherboard is not used; P entium III CPUs hav e the clock speed preset
and therefore switch S4 is ignored.

Fans

Inside the E-800A, a front fan and a back panel fan run continuously when the system is
running. You should hear the fans start as soon as you power on the E-800A. If you do
not hear the fans, the most likely problem is a faulty power connection (see “To check
board and cable connections” on page 4-8).

The following procedures describe how to remov e and r eplace the front fan and the back
panel fan.

Front fan

The front fan circulates air inside the E-800A in order to cool highly integrated circuits
within the system.
