OVERVIEW
3. IEEE1394 BOARD (FIREWIRE) (B581)
3.1 OVERVIEW
An IEEE1394 interface board is available as an option for this machine to provide
high speed connectivity through what is commonly called Firewire or i.LINK (Sony).
Some important advantages of Firewire are:
• High speed data transmission at 400 Mbps.
• Easier connectivity (many devices can be connected without a host).
• Devices in a computer can be connected to external devices on a shared bus.
IEEE1394 supports two printing methods: 1) SCSI Print, and 2) IP Over 1394. IP
Over 1394 supports printing by setting an IP address, and SCSI supports printing
without an IP address.

OVERVIEW
24 January, 2003
When the host computer powers up, it queries all the devices connected to the bus
and assigns each one an address, a process called enumeration. Here are some
general features of Firewire:
• Firewire is Plug-and-Play.
• Firewire devices are hot pluggable (they can be plugged while the system is
operating).
• Firewire uses 64-bit fixed addressing, based on the IEEE 1212 standard. There
are three parts to each packet of information sent by a device over FireWire:
• 10-bit Bus ID. Used to determine the Firewire bus where the data came from.
• 6-bit Physical ID. Used to identify the device that sent the data.
• 48-bit Storage Area. Capable of addressing 256 terabytes of information for
each node
• The Bus ID and Physical ID comprise the 16-bit Node ID. 64,000 nodes are
allowed on each system.
• Up to 16 hops are allowed (4.5 m/hop) for a total of 72 meters devices are daisychained.
• Firewire allows its devices to draw power from the Firewire connection. Two
power connectors in the cable can supply power (8 to 40 V, 1.5 amp max.)
• An important element of Firewire is its support of isochronous devices.
When isochronous devices are in the isochronous mode, data streams between
the device and the host in real time with guaranteed bandwidth and no error
correction. Essentially, this means that a device like a digital camcorder can
request that the host computer allocate enough bandwidth for the camcorder to
send uncompressed video in real time to the computer. The camera can sent
data via the Firewire connection in a steady flow to the computer without
anything disrupting the process. This is one of the main reasons why 1394 has
been widely adopted by the consumer electronics industry.

4.1 SPECIFICATIONS
USB connectivity is provided as an option for this machine.
Interface
Data rates
USB 1.1, USB 2.0
480 Mbps (high speed), 12 Mbps (full speed), 1.5 Mbps (low speed)
High speed mode is only supported by USB 2.0.
4.2 USB 1.1/2.0
USB (Universal Serial Bus) offers simple connectivity for computers, printers,
keyboards, and other peripherals. In a USB environment, terminators, device IDs
(like SCSI), and DIP switch settings are not necessary.
USB 1.1 provides the following features:
• Plug & Play. As soon as a new device is connected via USB, the operating
system recognizes it, and the appropriate driver is installed for it automatically if
the driver is available. If the driver is not available, a message prompts the user
for the driver disk for immediate installation.
• Hot swapping (cables can be connected and disconnected while the computer
and other devices are switched on)
• No terminator or device ID required
• Data rates of 12 Mbps (full speed), and 1.5 Mbps (low speed)
• Common connectors for different devices
• Bi-directional data communication between device and host computer via a 4byte header and DEVICE ID.
Up to 127 devices can be connected and 6 cascade connections are allowed.
Power is supplied from the computer and the maximum cable length is 5 m.

Peripherals
USB 2.0 is an evolution of the USB 1.1 specification. It uses the same cables,
connectors, and software interfaces so the user will see no change. It provides an
easy-to-use connection to a wide range of products with a maximum data rate of
480Mbps (high speed).
USB CONNECTORS

4.3 USB CONNECTORS
USB is a serial protocol and a physical link, which transmits all data on a single pair
of wires. Another pair provides power to downstream peripherals. The USB
standard specifies two types of connectors, type “A” connectors for upstream
connection to the host system, and type “B” connectors for downstream connection
to the USB device.

4.4 REMARKS ABOUT USB
• The machine does not print reports specifically for USB.
• Only one host computer is allowed for the USB connection.
• After starting a job using USB, do not switch the printer off until the job has been
completed. When a user cancels a print job, if data transmitted to the printer has
not been printed at the time of cancellation, the job will continue to print up to the
page where the print job was cancelled
• When the controller board is replaced, the host computer will recognize the
machine as a different device.
4.4.1 RELATED SP MODE
“USB Settings” in the printer engine service mode. Data rates can be adjusted to
full speed fixed (12 Mbps). This switch may be used for troubleshooting if there is a
data transfer error using the high speed mode (480Mbps).
Data rates can also be adjusted using the UP mode “USB Setting” in the Host
Interface in the System menu. This mode can be accessed only when the “Enter”,
“Escape”, then “Menu” keys are pressed to enter the UP mode.

5.1 WIRELESS LAN SPECIFICATIONS
The IEEE 802.11b wireless LAN interface card is available as an option for this
machine.
A wireless LAN is a flexible data communication system used to extend or replace
a wired LAN. Wireless LAN employs radio frequency technology to transmit and
receive data over the air and minimize the need for wired connections.
• With wireless LANs, users can access information on a network without looking
for a place to plug into the network.
• Network managers can set up or expand networks without installing or moving
wires.
• Most wireless LANs can be integrated into existing wired networks. Once
installed, the network treats wireless nodes like any other physically wired
network component.
• Flexibility and mobility make wireless LANs both effective extensions of and
attractive alternatives to wired networks.

WIRELESS LAN TRANSMISSION MODES
24 January, 2003
5.2 WIRELESS LAN TRANSMISSION MODES
Wireless communication has two modes: 1) ad hoc mode, and 2) infrastructure
mode.
5.2.1 AD HOC MODE
The ad hoc mode allows
communication between each device
(station) in a simple peer-to-peer
network. In this mode, all devices
must use the same channel to
communicate. In this machine, the
default transmission mode is ad hoc
mode and the default channel is 11.
First, set up the machine in ad hoc
mode and program the necessary
settings, even if the machine will be
used in the infrastructure mode.
B580D907.WMF
To switch between ad hoc and
infrastructure modes, use the
following user tool: Host Interface
Menu - IEEE802.11b - Comm Mode
5.2.2 INFRASTRUCTURE MODE
The infrastructure mode allows
communication between each
computer and the printer via an
access point equipped with an
antenna and wired into the network.
This arrangement is used in more
complex topologies. The wireless
LAN client must use the same SSID
(Service Set ID) as the access point
in order to communicate.
Access Point

WIRELESS LAN SECURITY FEATURES
5.3 WIRELESS LAN SECURITY FEATURES
SSID (Service Set ID)
The SSID is used by the access point to recognize the client and allow access to
the network. Only clients that share the same SSID with the access point can
access the network.
NOTE: 1) If the SSID is not set, clients connect to the nearest access point.
2) The SSID can be set using the web status monitor or telnet.
5.3.1 USING THE SSID IN AD HOC MODE
When the SSID is used in ad hoc mode and nothing is set, the machine
automatically uses “ASSID” as the SSID. In such a case, “ASSID” must also be set
at the client.
NOTE: SSID in ad hoc mode is sometimes called “Network Name.”
Some devices automatically change from ad hoc mode to infrastructure mode
when the same SSID is used in ad hoc mode and infrastructure mode. In such a
case, to use the device in ad hoc mode, use a specified SSID in infrastructure
mode and use “ASSID” in the ad hoc mode.
WEP (Wired Equivalent Privacy)
WEP is a coding system designed to protect wireless data transmission. In order to
unlock encoded data, the same WEP key is required on the receiving side. There
are 64 bit and 128 bit WEP keys. However, this machine supports only 64 bit WEP.
NOTE: The WEP key can be set using the Web Status Monitor or Telnet.
Peripherals
MAC Address
When the infrastructure mode is used, access to the network can also be limited at
the access points using the MAC address. This setting may not be available with
some types of access points.

is being used.
5.4.2 CHANNEL SETTINGS
If a communication error occurs because of electrical noise, interference with other
electrical devices, etc., you may have to change the channel settings.
To avoid interference with neighboring channels, it is recommended to change by 3
channels. For example, if there are problems using channel 11 (default), try using
channel 8.

has been installed.
3) Check if the channel settings are correct.
4) Check if the SSID and WEP are correctly set.
If infrastructure mode is being used,
1) Check if the MAC address is properly set.
2) Check the communication status.
If the communication status is poor, bring the machine closer to the access
point, or check for any obstructions between the machine and the access
point.
If the problem cannot be solved, try changing the channel setting.

6. MEDIA LINK BOARD (B609)
Copy and print jobs are stored on the document server (on the copier’s hard disk)
in a Ricoh proprietary file format.
In previous models (such as A-C2, R-C2), DeskTopBinder could retrieve copy and
print jobs from the document server and convert them to TIFF. However, this
software-based conversion was slow for many users.
So, for the B070/B071, this conversion has been made hardware-based, using the
optional Media Link Board. Without the Media Link Board, copy and print jobs
cannot be downloaded to a PC from the document server.
Two common target formats are provided for conversion to files that can be viewed
on a computer: JPEG and TIFF.
NOTE: If the printer/scanner controller is not installed, the optional standalone NIB
must be installed in the copier.
SP5847 (Net File Mag. Rate) is provided for use with this feature. For more details
about these settings, see Section “5. Service Tables” in the main Service Manual.
NOTE: These SP commands are enabled for use only after the MLB has been
installed. For details about installing the MLB, see Section “1. Installation”
of the main Service Manual.
