INTRODUCTION 7
INTRODUCTION
This document includes information about servicing the Canon imagePASS-A2. In this
document, Canon imagePASS-A2 is referred to as “the imagePASS.”
About the imagePASS
The imagePASS embeds computer connectivity and highly efficient PostScript and PCL
printing capacity into the Canon imageRUNNER ADVANCE C9200/C7200 series copier.
It allows the customer to use the copier as a PostScript printer and scanner, and it provides
efficient image processing and printing controls. Once it is connected to the copier through a
network, customers can print to the imagePASS from supported client computers on the
network (Windows or Mac, or a UNIX workstation running TCP/IP).
The imagePASS ships with system software installed so that customers can use the imagePASS
immediately. However, as part of servicing the imagePASS, you may need to reinstall system
software.

INTRODUCTION 8
How the imagePASS operates
When a customer prints, the motherboard and copier interface board process image data.The
copier interface board is a custom board and allows the imagePASS to communicate with the
copier. The CPU, which is located on the motherboard, controls the transfer of image data to
and from the motherboard and runs the interpreter. DIMMs, which are also located on the
motherboard, hold image data during printing.
The interpreter rasterizes the page description file and compresses the image pattern into
memory using compression technology. The interpreter outputs the compressed raster data
through the image frame buffer memory to the copier interface board. The raster data is sent
to the copier, which then renders the image on paper at maximum speed.

SERVICE PROCEDURES 9
SERVICE PROCEDURES
This chapter includes information about checking internal and external connections,
removing and installing components, and verifying that the imagePASS works after service.
Before servicing the imagePASS
It is strongly recommended that before you service the imagePASS, you carefully read all
precautions and notices (see pages 9-12).
Also, keep in mind that the most common cause of a hardware problem is a faulty or loose
connection. Before you replace an expensive component, check internal and external
connections (see page 23).
Precautions
This section includes information about how to safely operate and service the imagePASS and
how to avoid damage to imagePASS components.
Report shipping damage
If there is evidence of shipping damage, save the shipping boxes and damaged parts. Call the
shipper immediately to file a claim and notify your authorized service/support center.
Do not change an existing network
The imagePASS is probably 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 site administrator.
Do not assign an IP address to the imagePASS
Only the site administrator should assign an IP address to a network device, including the
imagePASS. If you enter an incorrect IP address for the imagePASS, errors may occur on
connected devices.
Handling boards
When handling a printed circuit board, do not bend it. Hold it by opposing edges, rather
than by the corners.

SERVICE PROCEDURES 10
Handling the hard disk drive
To ensure that you do not damage the hard disk drive, do the following:
• Follow electrostatic discharge (ESD) precautions.
• Keep magnets and magnetic-sensitive objects away from the hard disk drive.
• Do not loosen or remove the screws on the top of the hard disk drive. Doing so voids the
warranty.
• Handle the hard disk drive by its sides and avoid touching the printed circuit board.
• Do not drop, jar, or bump the hard disk drive.
• Before you remove or install a hard disk drive, allow it to reach room temperature.
Avoid magnets
Keep magnets and magnetic-sensitive objects away from electronic components, especially the
hard disk drive.
Electrostatic discharge
When you work with electronic components, electrostatic discharge is a concern since it can
destroy circuits, or damage them, reducing their life span. The area around the copier is most
likely not static-free, and electrostatic discharge could occur.
Do the following to avoid damage due to electrostatic discharge:
• Work on a grounded antistatic mat.
• Wear an antistatic wristband, attached to the same location as the antistatic mat.
• Before you remove an electronic component from the shipping box, touch a metal area
of the copier to discharge static from your body.
• After you remove an electronic component from the shipping box, place it face up on a
grounded antistatic surface.
• Leave electronic components in antistatic bags until you are ready to use them.
• Do not walk on carpet or vinyl while carrying an electronic component, unless it is in an
antistatic bag.
• If you remove an electronic component from the copier, immediately place it in an
antistatic bag.
The power cable
Observe the following guidelines:
• Only use the power cable that shipped with the imagePASS or an appropriate replacement
power cable. For replacement parts, see your authorized service support center.
• Before you open the imagePASS, unplug the imagePASS.
• Keep the power cable away from foot traffic.
