HP LaserJet M9040/M9050 MFP - Software Technical Reference (external)

Three messages appear during a normal update process; others appear only if the update process does
not succeed.
Table 6-2 Firmware 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 the RECEIVING UPGRADE message 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 actually reprogramming the firmware.
NOTE: If power is lost during the flash DIMM update (while the PERFORMING
UPGRADE message 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
by any means that is supported by the device, regardless of the connection
(network or USB).
RFU LOAD ERROR
SEND RFU UPGRADE
ON USB PORT
This message appears (in English only) if the firmware update of the formatter
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 USB port of the device.
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.
To print a configuration page from the product control panel, perform the following:
1. Touch Administration.
2. Touch Information.
3. Touch Configuration/Status Pages.
4. Touch Configuration Page.
5. Touch Print.
NOTE: If the product contains an HP Jetdirect EIO print server or an optional hard disk drive, additional
configuration pages print that provide information about those options.
The firmware datecode is listed on the configuration page in the section titled Device Information. The
firmware datecode has this format: YYYYMMDD XX.XXX.X. The first string of numbers is the date,
where YYYY represents the year, MM represents the month, and DD represents the day. For example,
a firmware datecode that begins with 20071210 represents December 10, 2007. The second string of
numbers represents the firmware version, such as 50.002.0.
