Print a menu map
Print a menu map before updating the firmware to see what user settings have been configured in the
current firmware. This menu map can be compared with a menu map printed after the firmware update
to determine what user settings have been added or changed in the new firmware.
To print a menu map from the device control panel:
1. Touch Administration.
2. Touch Information.

Downloading the new firmware from the HP Web site
The remote firmware update (.RFU) file and an associated readme file are packaged together as a self-
extracting .EXE file. For detailed instructions about how to download the .EXE file, go to the following
URL:
www.hp.com/go/ljm4345mfp_firmware
The .EXE file consists of a readme file and the .RFU file.
For UNIX systems, the remote firmware update file is a .TAR file.
For firmware upgrades on Macintosh systems, see
Update Firmware.
Downloading the new firmware to the device
For support information about downloading new firmware from the Web, go to the following URL:
www.hp.com/go/ljm4345mfp_firmware
The device can receive an RFU update when in the 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 (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.
