Updating the Firmware
Never turn the machine's main power off while the firmware is being updated, because this
could damage the main board.
Before Updating the Firmware
Check your operating environment before beginning the update.
Compatible Operating Systems
The computer must be running one of the following operating systems:
Windows Vista (32/64 bit)/ 7 (32/64 bit)/ 8.1 (32/64 bit)/ 10 (32/64 bit)
Windows Server 2008/ Server 2008 R2/ Server 2012/ Server 2012 R2/ Server 2016
OS X 10.10 or later
Linux OS
Ubuntu 16.04LTS/ 16.10 (x86 & x64)
openSUSE 13.1/ 13.2 (x86 & x64)
Red Hat Enterprise Linux 6/ 7 (x86 & x64)
Backing Up the Machine’s Settings
After the firmware update, the machine’s settings may return to their factory defaults.
Before you reconnect the machine for the update, back up the machine’s settings by accessing the
machine using a web browser from a computer connected via a network. For details, refer to the
"User's Guide".
Also, print out a configuration page using [Print List/Report] on the control panel or a web browser. For
details, refer to the "Reports".
Connection
Connect your computer and the machine through a network or directly by USB.
Make sure a computer is securely connected to the machine with the USB or network cable
that you will be using for the firmware update.
We recommend that you update the firmware via USB. If updating the firmware over the
network, the machine may receive data over the network such as a print job during the
updates, which can interfere with the update process.
If updating the firmware via USB, the printer driver for USB connection must be installed on a
computer beforehand. However, if updating via a network, no printer driver is necessary.
Disconnect any other cables that are not necessary for the firmware update, such as a
telephone cable, from the machine.
