This message appears from the time the product has finished reprogramming the DIMM until the product 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 fails to update. Perform another update by any means that is supported by the product, regardless of the connection (network, parallel, or USB). 166 Chapter 6 Engineering Details ENWW

Update messages
Printer message
Explanation
RECEIVING UPGRADE
This message appears from the time the product recognizes the beginning of
an .RFU update until the time the product 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
product control panel to indicate that the update was interrupted.
PERFORMING UPGRADE
This message appears while the product is actually reprogramming the firmware.
NOTE:
If power is lost during the flash DIMM update (while
PERFORMING

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 product has finished reprogramming the
DIMM until the product reinitializes.
RESEND UPGRADE
This message appears (in English only) if the firmware update fails because the
