HP LaserJet P4010 and P4510 Series - Software Technical Reference

The .EXE file consists of a readme file and the .RFU file.
NOTE: For UNIX systems, the remote firmware update file is a .TAR file.
Downloading the new firmware to the device
For support information about downloading new firmware from the Web, go to www.hp.com/go/
ljp4010series_software or www.hp.com/go/ljp4510series_software.
The device can receive an RFU update when the device is in a READY state. The device waits for all
of the I/O channels to become idle before performing the update.
NOTE: If the firmware update involves a change in the format of nonvolatile random-access memory
(NVRAM), any menu settings that are changed from the default settings will return to default settings.
The settings must be changed again if you want them to be different from the defaults. Examples of
settings that are affected in this way are tray types, default symbol sets, and Web-access alerts.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for the
device to reinitialize. The I/O transfer time depends on a number of things, including the speed of the
host computer that is sending the update and the I/O method (parallel or network). The reinitialization
time depends on the specific hardware configuration of the device, such as the number of EIO devices
installed, the presence of external paper-handling devices, and the amount of memory that is installed.
Finally, any print jobs that are ahead of the RFU job in the queue are printed before the update is
processed.
Use one of the methods described in this manual to update the printer firmware.
Printer messages during the firmware update
The following table lists the causes and results of possible interruptions to the firmware update.

Cause Result
The job was cancelled from the control panel. No update has occurred.
A break in the I/O stream occurred during send (for example,
the parallel cable was removed).
No update has occurred.
A power cycle occurred during the RECEIVING UPGRADE
process.
No update has occurred.
A power cycle occurred during the PERFORMING
UPGRADE process.
No update has occurred. Resend the update through a parallel
port.
A power cycle occurred during the INITIALIZING process. The update has been completed.
Print jobs that are sent to the device while an update is in process do not interrupt the update.
All HP LaserJet devices leave the factory with the most recent firmware version installed. If a remote
firmware update fails in an MS Windows operating system, the .RFU file must be resent.
If a remote firmware update fails in a Macintosh operating system, contact support from an HP Customer
Care Center.
