Updating product firmware

 

Downloading a remote firmware update

 

The HP LaserJet 4100mfp product supports remote firmware updates (RFUs). The update is

 

downloaded from the website http://www.hp.com/go/lj4100_firmware (downloading a firmware

 

update is similar to downloading printing-system software and printer drivers).

 

This website also features an “E-mail me when new software is available” link. This feature

 

notifies you by e-mail when a new firmware update version is available for the MFP. If you used

 

HP WebReg to register your product, you are automatically sent an e-mail notification when a

 

new firmware update version is available for the MFP.

 

 

Hint

The RFU file on the website is a self-extracting .EXE file. Detailed instructions about how to

 

download the RFU file can be found at the website http://www.hp.com/go/lj4100_firmware.

 

 

 

The RFU process consists of three steps:

 

● Determine the version of firmware currently installed (print a configuration page; see

 

“Configuration page” on page 130). Look for the version information in the device information

 

section of the configuration page.

 

● Go to the website http://www.hp.com/go/lj4100_firmware website and download the update.

 

● Install the update.

 

 

Note

For more information about remote firmware updates, contact your HP Customer Care Center

 

and ask for a software technical reference sheet (see “Support” on page 144).

 

 

 

Installing the update

CAUTION

Note

If a firmware update involves a change in the format on nonvolatile random-access memory (NVRAM), any user-set settings (for example, configure device settings) revert to default settings. Before installing an updated version of the firmware, print any information pages required to reset user defined settings. See “Evaluate the information pages” on page 130.

To install a firmware update on a computer using the UNIX operating system, use any method that delivers the .RFU file to the printer. For example, $cp/home/yourmachine/FILENAME/dev/ parallel where /home/yourmachine/FILENAME with substitutions for the locations that contain the location of the .RFU file.

RFU installation messages

During normal RFU installation the following three messages appear on the control-panel display.

●Recieving Upgrade

•This message appears from the time the printer recognizes the beginning of a .RFU file being sent until the time the printer verifies the validity and integrity of the .RFU file.

●Performing Upgrading For Help Press?

•This message appears while the printer is reprogramming the DIMM with the .RFU file information.

●Wait For Printer To Reinitialize

•This message appears from the time the printer finishes reprogramming the DIMM until the printer re-initializes.
