Reference Guide

Three messages appear during a normal update process; a fourth (RESEND UPGRADE) appears only
if the update process does not succeed.
Table 6-7 Update messages
Device message Explanation
RECEIVING UPGRADE This message appears from the time the device recognizes the beginning of
an .RFU update until the time the device has verified the validity and integrity of
the .RFU update.
NOTE: 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. No message appears on the device
control panel to indicate that the update was interrupted.
PERFORMING UPGRADE This message appears while the device is reprogramming the firmware.
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 that the device has finished reprogramming
the DIMM 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
by any means that is supported by the device, regardless of the connection
(network, parallel, or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
This message appears (in English only) if the firmware update fails because the
print-engine firmware is corrupted.
NOTE: To verify that the firmware update succeeded, print a new configuration page from the control
panel and verify that the firmware date code on the configuration page has changed.
