1. OVERVIEW
The remote firmware update function (referred to as RFU) is used to update the
firmware remotely. Service representatives do this over the network. Note that this
information is intended for service representatives only and not for end users.
2. SUPPORTED MODELS AND FIRMWARE
The models supporting RFU and the types of firmware that can be updated are shown

5. UPDATING PROCEDURE
Recommendation:
It is strongly recommended that RFU be performed on-site, to minimize the chances of a
power-down during RFU.
5.1Auto Rebooting
After receiving new firmware, the machine firmware is updated and the machine is
automatically rebooted using the updated firmware. Fig.2 shows the kind of reboot
required after the firmware is updated.

5.2 Preparation
Before you update the firmware by RFU, carry out three items as shown below.
5.2.1 Checking the IP address
For a machine with static IP address:
• Search for the IP address using SmartDeviceMonitor for Admin or Web
• SmartDeviceMonitor.
• If the hostname of the machine is registered in a DNS server, use the nslookup
command with the machines hostname. This can also be used for dynamic IP
addresses if you are using DDNS.
• If the computer name of the machine is registered in a WINS server use the
<……..> command.
For a machine with a dynamic IP address:
• Print the config sheet or the SMC for the machine.
• Check the IP address in the DHCP server.
5.2.2 Firmware
• Please download firmware (*.rru or *.rfu files) from our support site and store it in
a folder on a local PC to be used for RFU.
5.2.3 Checking the machine status
• Please check the status of the target machine using WebImageMonitor or
SmartDeviceMonitor.

5.5 Firmware Update for Centronics (IEEE1284)
Note:
• Firmware update via a centronics interface does not require a password.
• The only method of recovery available via a centronics interface is an IC or SD
card.
1. Check the target firmware version by printing out the SMC sheet with SP5-990-4.
2. Set SP5-856-2 to a value of 1. This will configure the machine for firmware update
via the Centronics I/F.
3. Send the firmware to the target machine with the copy command.
C:\>copy/b “file name”
4. Cycle the machine’s power (off then on).
5. Confirm the firmware version as shown in step 1.
6. Update all required firmware by repeating steps 1 to 5 as necessary.

5.6Checking the Result of the Update
Check that the firmware has been updated.
Note:
• After transmitting the firmware file from the computer, it takes approximately 3 to 5
minutes for updating to complete and the machine to restart.
• To check the result, you need to logon to the machine again using ftp. However,
you cannot log on during the update process, so you are unable to check that the
update has completed until the machine has restarted.
If the update was successful
• Once the firmware has been updated successfully, the system automatically
restarts using the new firmware.
After the restart, verify that the firmware has been updated to the new version.
Check that the error code in the error data file (errlog.txt) is "0" by performing
procedure 7.1 “Checking the error status” (below).
If an error occurs
• If an error occurs during the update, the system automatically restarts, the
message shown below appears, and the machine waits to receive the firmware
file again. If the update is interrupted by a power failure, the same thing happens
once the power is restored.
Log on to the machine again using ftp and then resend the firmware file to the
machine.
The following message appears for Type 1 firmware:
o Display panel (MFPs)
o Display (Printers)

6. ERROR RECOVERY
There are three ways to recover from a loss of power during RFU.
6.1 Recovery Procedure
There are three types for recovery after a power loss during RFU. (This will depend on
the firmware and model). Procedures for types 1, 2 and 3 are on the next page.
Find the firmware and model you are downloading to, and begin with the type shown
in the table below.
Recommendation:
As mentioned in 5. Updating Procedure, it is strongly recommended that RFU be
performed on-site, to minimize the chances of a power-down during RFU.

Important: Do not turn the main power off while you perform any of the procedures.
Procedure for type 1:
1. Restore power to the machine. The machine will wait for the operator to start the
update.
2. Connect to the machine by FTP and upload the *.rru or *.rfu files.
Procedure for type 2:
1. Try ‘Procedure for type 1’.
2. If this does not work, restore power to the machine.
3. Upload the firmware from an SD card or IC card.
Procedure for type 3:
1. Try ‘Procedure for type 1’.
2. If this does not work, try ‘Procedure for type 2’.
3. If this does not work, replace the internal SD card or circuit board.

7. TROUBLESHOOTING
7.1 Checking the error status
You can check the error status using ftp.
Check whether an error occurred by viewing errlog.txt. This file is in the same
directory as version.txt.
1. Logon to the machine using ftp.
2. Enter "dir" to check that errlog.txt exists.
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for '/'.
-r--r--r-- root root 200 Jan 1 01:08 help

-r--r--r-- root root 200 Jan 1 01:08 errlog.txt
226 Transfer complete.
ftp: 191 bytes received in n.nn Seconds n.nn Kbytes/sec.

3. Enter "get errlog.txt -" to check the error code.
ftp> get errlog.txt -
200 PORT command successful.

The information in errlog.txt consists of the module IDs of the firmware modules
that caused errors and the corresponding error codes.
For what the error codes mean and how to respond to them, see section 7.2
(below).
4. Enter "bye" to exit ftp.
