Introduction
Symbols Used
This documentation uses the following symbols to indicate special information:
Symbol Description
Indicates an item of a non-specific nature, possibly classified as Note,
Caution, or Warning.
Indicates an item requiring care to avoid electric shocks.
Indicates an item requiring care to avoid combustion (fire).
Indicates an item prohibiting disassembly to avoid electric shocks or
problems.
Indicates an item requiring disconnection of the power plug from the electric
outlet.
Memo
REF.
Indicates an item intended to provide notes assisting the understanding of the
topic in question.
Indicates an item of reference assisting the understanding of the topic in
question.
Provides a description of a service mode.
Provides a description of the nature of an error indication.
Introduction
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the
relationship between electrical and mechanical systems with reference to the timing of
operation.
In the diagrams, represents the path of mechanical drive; where a signal name
accompanies the symbol, the arrow indicates the direction of the electric
signal.
The expression "turn on the power" means flipping on the power switch, closing the front
door, and closing the delivery unit door, which results in supplying the machine with
power.
2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is
"High", while '0' is used to indicate "Low".(The voltage value, however, differs from
circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD
signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked
in the field. Therefore, the operations of the microprocessors used in the machines are
not discussed: they are explained in terms of from sensors to the input of the DC
controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product
improvement or other purposes, and major changes will be communicated in the form of
Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this
Service Manual and all relevant Service Information bulletins and be able to identify and
isolate faults in the machine."

1.2 Specifications
1.2.1 Specifications
The Security Expansion Board (USB)-D1, an optional board connected with PCI, has 2
functions. One is to add 2 USB host terminals required when the IC card reader or the like
is connected to the host machine with USB in MEAP environment.
The other is to add the encryption accelerator chip required when HDD encryption
processing is speeded up during installation of the security kit.
The USB host interface function becomes enabled by combination with an USB-supported
MEAP application. The encryption accelerator function cano be used only while the
security kit is enabled.
The PCI Bus Extension Kit is necessary to install the Security Expansion Board (USB)-D1.
Main specifications of the Security Expansion Board (USB)-D1 are as follows:
USB Host Interface Function
- USB full speed (equivalent to USB1.1)
- USB host terminal: 2 pcs.
- Max. power supply at the host terminal: 500mA per port
Encryption Accelerator Function
- Encryption processing accelerator IC Motorola-made MPC190
- Supported encryption system
Public key cryptogram system: RSA Diffie-Hellman,
Elliptic curve cryptogram system
Common key encryption system: DES, 3DES, RC4

2.2.2 Mounting the Ferrite Core (outside North America)
0007-8168
Be sure to perform the following if you are using a USB cable for connection of a USB
device.
1) When you have connected the USB cable, fit the ferrite core [1] to the cable. Be sure that
the distance shown [2] is 100 mm or less.
To prevent noise, fit the ferrite core as shown.
- Take care so that the harness is not trapped by the ferrite core.
