Important Note Regarding the G0885123 Engine Board
The G0885123 engine board was mistakenly registered with service parts, but is useable with a
minor modification (detailed on pg. 2). In addition, the correct boards have been newly registered
with service parts and are listed below:
• Old part number: G0885123
• New part number: G0885121 for NA (G091-11, -17)
G0885122 for EU, Asia, China (G091-22, -27, -69)
Note: Refer to MB #G091003 for details about this P/N change.
! Action in the Field
1. If the old board above has not been ordered (none in stock), there is no need to take any
action. Please simply use the new P/N listed above and in the MB whenever ordering the
board.
2. If there are old boards in stock, perform the minor modification described below on the old
stock.
3. If some old boards have already been installed in machines in the field, perform the minor
modification below on the old boards at the next service visit.
!
Possible Symptoms with the Unmodified Old Boards
The following may occur when using the unmodified old boards, but please note that even in
such cases the machine is well within product safety parameters.
• Fusing-related symptoms (e.g. poor fusing, paper curling), the machine may not satisfy
certain EU regulations.
• Discrepancy between the paper size dial setting and the LCD display, which may result in a
paper size error or paper jam.
• Garbled characters may be displayed when using display languages other than English.
! Difference Between the Old and New Boards
The old engine board (G0885123) contains two resistors, R1 and R2, but the new board for NA
(G0885121) contains only R2 and the new board for EU/Asia (G0885122) contains only R1.

Minor Modification of old G0885123 Engine Board to its New Version
1. If the old engine board is already installed in the machine:
i) Open the front door.
ii) Remove the operation panel (2 hooks, 1 harness).
iii) Remove the rear cover and option top cover.
iv) Remove the top cover (4 screws).
v) Remove the left cover (2 screws).
2. For NA version
Remove R1 as shown below using a pair of wire cutters (nippers).
For EU/Asia version
In the same manner,
remove R2 using a pair of wire cutters.

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.
