Table 7-9 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 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 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 becomes is corrupted. Perform another update
by any means that is supported by the printer, regardless of the connection
(network, parallel, or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
ON PARALLEL PORT
This message appears (in English only) if the firmware update fails because the
print-engine firmware is corrupted.
If this message appears, the update must now be sent only by a computer that is
attached to the parallel port of the product.
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.
