NOTE The MFP turns off and then on automatically to activate the update. When the update
process is complete, a Ready message displays on the MFP control panel.
Using FTP to upgrade the firmware on a network connection
NOTE The MFP can receive an .RFU file update as long as it is in a "ready" state.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the
MFP to reinitialize. The I/O transfer time depends on a number of things, including the speed of the host
computer that is sending the update. If the remote firmware update process is interrupted before the
firmware is downloaded (while Receiving upgrade appears on the control-panel display), the firmware
file must be sent again. If power is lost during the flash DIMM update (while the Performing upgrade
message appears on the control-panel display), the update is interrupted and the message Resend
upgrade appears (in English only) on the control-panel display. In this case, you must send the upgrade
by using the parallel port. Finally, any jobs that are ahead of the RFU job in the queue are completed
before the update is processed.
Follow these instructions to perform the upgrade by using FTP.
NOTE The firmware update involves a change in the format of nonvolatile random-access
memory (NVRAM). Any menu settings that are changed from the default settings might return to
default settings and must be changed again if you want settings that are different from the
defaults.
