Three messages appear during a normal update process; a fourth (RESEND UPGRADE) appears only
if the update process does not succeed.
Table 7-3 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 product, regardless of the connection
(network, parallel, or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
ON <X> PORT
where X = Network or USB
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.
Downloading custom color profiles
Obtain custom color profiles just as you would any other remote-firmware update, using the procedures
described in these sections.
Custom color-profile .RFU files are named as follows:
clj####_<what>_<version>.RFU
where:
●
#### is the product-model number of the color table
●
<what> is a one-word description of what the table does
●
<version> is a two-part version number consisting of a major and a minor value
