Installation Instructions

NOTE:  Please be aware that an update in some circumstance may require ten minutes or more to complete.
Upgrading firmware to a single device
You can send an .RFU update to a device at any time; the device will wait for all I/O channels to become idle before cycling power. 

Please print a configuration page prior to performing any firmware update. To print the configuration page:

1.	Go to the printer’s or MFP’s control panel. 
2.	Press the “Administration” Icon on the touch screen. 
3.	Select the "INFORMATION" selection on the touch screen. 
4.	Select "CONFIGURATION/STATUS PAGES”. 
5.	Select “CONFIGURATION PAGE”.
6.	Select the “Print” button. 
On the printed CONFIGURATION page look in the section marked "Device Information" for the firmware date code.  The firmware date code will look something like this:   20040322 48.001.0

NOTE: If the firmware update involves a change in the format of NVRAM, the NVRAM settings will be lost and must be set again by the customer. 

The elapsed time for an update depends on the I/O transfer time as well as the time that it takes for the printer to reinitialize.  The I/O transfer time will depend on a number of things including the speed of the host computer sending the update and the I/O method (parallel, or network). 
The re-initialization time will depend on the specific hardware configuration of the printer, such as the number of EIO devices installed, the presence of external paper handling devices, and the amount of memory installed.  Finally, any print jobs ahead of the .RFU job in the queue will be printed before the .RFU update is processed. 

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.

Using FTP from Internet Explorer:
Take note of the TCP/IP address on the configuration pages. 

NOTE:  This method is not recommended with Windows Vista or if Internet Explorer 7 is installed on your pc due to frequent timeouts.  A stand-alone FTP client program is recommended for Windows Vista.

NOTE: Make sure that the printer is not in Power save mode.  Also, make sure that any error messages are cleared from the control panel display.
 
1.	Insure the "Enable folder view for FTP sites" box is checked on the Advanced tab under Tools/Internet Options. 
2.	Open the browser and type ftp://192.168.0.90 (this is an example). 
3.	Use the TCP/IP address of the printer from step 1).  The display will show a folder labeled Port 1. 
4.	Open Windows Explorer and navigate to the directory where the .rfu file is located. 
5.	Drag the rfu file from Windows Explorer to the Port 1 folder in step 2. 
6.	Verify the printer’s control panel displays “Performing Upgrade” 

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.

For Windows Systems: 
If the device is shared on the network, then the following command can be issued from a command prompt: 

copy /b FILENAME \\SHARENAME\PRINTERNAME 

where FILENAME is the name of the .RFU file, <SHARENAME> is the name of the machine, from which the printer is being shared, and <PRINTERNAME> is the printer's share name (do not type the angle brackets). 

If the device is attached locally, then the .RFU file can be sent directly to the printer with a COPY command from a command prompt or DOS window: 

Using USB

Before you can send a firmware upgrade through the USB port, you need to know the name of the computer the printer is connected to, and you need to enable printer sharing. These steps are for Windows® XP. Other versions of Windows operating systems are similar, with slightly different operations. 
How to find out the name of your computer: 
1.	Click the Start button, Programs, Accessories, System Tools, and then choose System Information. 
2.	You will find your computer’s name in the right window-pane next to System Name. 
3.	Write down this name as it will be needed later. 
How to share the connected printer: 
1.	Click the Start button, Settings, then Printers and Faxes. 
2.	Right-click the printer you need to send the upgrade to, then choose Sharing… 
3.	Choose the radio button labeled Share this printer. 
4.	Type a name for the share. Make it short and easy to remember. 
5.	Click Apply and write down the share name, as it will be needed later. 
1.	For example: “HP LaserJet mfp” 
2.	How to send the firmware upgrade using a USB connection: 
1.	Open a DOS Command Prompt (in Windows NT® 4.0, 2000, or XP, click Start, Run, then type CMD and press OK, or in Windows 9x click Start, Programs, Accessories, and then click MSDOS Prompt.) and locate the directory where you saved the firmware file. 
2.	Type: copy /b filename \\computer name\share name 
3.	For example: copy /b ljXXXXmfpfw_0X.00X.X.rfu \\computer1\HP LaserJet mfp printer
3.	Press Enter. 

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.

Using FTP:
If your HP LaserJet product uses a direct network connection, you can use file transfer protocol (FTP) to update your HP LaserJet firmware.  Take note of the TCP/IP address on the configuration pages. 

NOTE: Make sure that the printer is not in Powersave mode.  Also, make sure that any error messages are cleared from the control panel display.

1.	Open a DOS command window on your computer. 
2.	Type ftp <TCP/IP PRINTER ADDRESS>(for example, if the TCP/IP address is 192.168.0.90, type ftp 192.168.0.90). 
3.	Press ENTER on the keyboard. 
4.	When prompted for user name and password press ENTER for each. 
5.	Type bin at the >prompt. 
6.	Press ENTER. 
7.	Type: put <path> where <path> is the location where the .RFU file was downloaded from the Web. For example, type: 

put C:\LJXXXX\ljXXXXFW.RFU 

8.	Press ENTER. 
9.	Type "bye" at the command prompt once the download process begins and the firmware is updated on the printer 
10.	Press ENTER to exit the FTP session. 

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.

For Unix systems: 
Any method that delivers the .RFU file to the printer will work, including: 

$ cp /home/yourmachine/FILENAME /dev/ <XXXX>

where XXXX is the appropriate parallel device; and where /home/yourmachine/FILENAME contains the .RFU file. 

For Macintosh systems:

Mac OS X System (ftp)

1.	Open the Terminal application found in the Utilities folder; a terminal window will appear. 
2.	After the % symbol enter following information: 

ftp <<your printers IP address>>(example - % ftp 192.0.0.192)

The terminal window will list that you are connected to the printer and the JD FTP Server is Ready.
3.	Press the enter key twice.  Both the Username and Password can be blank 
4.	Enter the following information after ftp>: 

put <<path/Firmware File Name.rfu>>(Example - ftp> put /users/computername/Desktop/laserjet_fw.rfu)

Note: To ensure that the entire proper path to the .rfu file is placed in the put command, type in put and a space, then click and drag the .rfu file on to the terminal window.  The complete path to the file will be placed after the put command.

NOTE: When the upgrade process has completed the LaserJet will reboot. Once the printer is back online, print a Configuration Page and verify that the new firmware has been installed.
