5.1 FIRMWARE UPDATE
The machine firmware can be updated with packages downloaded from a Web site. The firmware
update procedure is described in the Operating Instructions and can be performed by the
operator.
5.1.1 BEFORE UPDATING THE FIRMWARE
Before you update the firmware:
 Print a Configuration Page before and after updating the firmware.
 Make sure that the machine is on and connected to the PC by its USB cable.
 Never disconnect the USB cable while the firmware is being updated.
 Make sure that the PC is set so it does not enter standby mode or sleep mode automatically
during the firmware update. The firmware update may take a while to complete, so you may
need to switch off the standby or sleep mode settings in the PC operating system.
 An Engine firmware update failure may trigger SC670, which can only be cleared by
replacing the main board.
 Because of this, make sure to do the following:
Always update the firmware in READY mode.
M135, M141, M143, M167, M149, M168, M150, M151, and M169 only: Unplug the fax
cable before starting the update.
Do not cut the power, unplug the USB cable, or do any other operation during the update.
5.1.2 FIRMWARE UPDATE PROCEDURE
