Device message Explanation
NOTE If power is lost during the flash DIMM update (while
PERFORMING UPGRADE appears on the control-panel display), the
update is interrupted and the message RESEND UPGRADE appears on
the control-panel display.
INITIALIZING This message appears from the time the device has finished reprogramming the
flash until the device reinitializes.
RESEND UPGRADE This message appears (in English only) if the firmware update fails because the
RFU process is interrupted. It can also occur if firmware for accessories (such as
the duplex unit or an output device becomes is corrupted. Perform another update
