  III.  UPGRADE INSTRUCTIONS 
************************************

NOTE:  Please be aware that an upgrade in some circumstance 
       may require approximately ten minutes to complete.

UPGRADING THE NEW FIRMWARE TO A SINGLE PRINTER 
------------------------------------------------- 
You can send an .RFU upgrade to a printer when in Ready state. The printer 
will wait for all I/O channels to become idle before cycling power. 

The elapsed time for an upgrade 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 
upgrade 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 upgrade is processed. 

NOTE: The printer will automatically restart after processing 
the upgrade. 

FOR WINDOWS SYSTEMS: 
--------------------
If the printer is shared on the network, 
then the following command can be issued from a command prompt: 

copy /b [FILENAME] \\COMPUTERNAME\SHARENAME 
  
where [FILENAME] is the name of the .RFU file, <COMPUTERNAME> is the 
name of the machine, from which the printer is being shared, 
and <SHARENAME> is the printer's share drive (do not type
the angle brackets). 

If the printer 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: 

 copy /b [FILENAME] Lptx 

where [FILENAME] is the name of the .RFU file and Lptx
is the name of the appropriate printer port (such as LPT1). 

Setting the following on the printer's control panel may help 
if a timeout message is seen on the computer monitor 
during an upgrade:

Change the timeout in the control panel
a. Press the MENU key
b. Scroll down to CONFIGURE DEVICE, press SELECT
c. Scroll down to I/O, press SELECT
d. With I/O TIMEOUT highlighted, press SELECT
e. Enter 300 and press SELECT (this sets the timeout to 300 secs)
 
The following can also be set on the computer to help address 
a timeout message that is seen on the computer monitor 
during an upgrade:

From a command prompt or DOS window type the following 
command and press the enter key:

  Mode lpt1:,,p

If the printer is attached to a parallel port other than LPT1, 
then substitute the proper LPT port number in the MODE command.

Once this command has been set the file can then be copied to 
the printer with the above mentioned COPY command.


For Novell Networks:
--------------------

-Copy the upgrade firmware file to a known directory
-Capture the Novell print queue
-Copy the upgrade file to the captured queue

Copying the upgrade firmware file to a known directory:

1. Find the file {current version of firmware you downloaded from 
   the web} and copy it to the root of a local drive or to a 
   directory close to the root.   (i.e. c:\firmware)
2. Make note of the directory for future use and confirm file 
   is there.

Capturing the Novell print queue (BPJ02357):

1.  Go to a DOS prompt.
2.  Type ENDCAP L=1 (With later Novell clients, the command is 
    CAPTURE /ENDCAP L=1.
3.  Press Enter
4.  The message "Device LPT1 is set to local mode" should appear.
5.  Type Capture L=1 Q=[Queue name] NFF NB NT TI=10
6.  Press Enter
7.  If you wish to test communication, type dir>lpt1.  If the 
    directory prints, the queue has been successfully captured.

Copy the upgrade file to the captured queue:

1.  Go to DOS prompt
2.  Navigate to the directory where the upgrade file is saved
3.  Type COPY /b {Filename} lpt1:
4.  The message "1 File copied" should appear and the printer 
    should indicate the firmware file is being processed.


USING FTP:
----------

Remote firmware update using FTP on a direct network connection

If your HP LaserJet product uses a direct network connection, 
you can use file transfer protocol (FTP) to update your HP 
LaserJet firmware.  

Complete the following steps:

1. Take note of the TCP/IP address on the EIO X JetDirect page 
   (this is the second page of the Configuration Page printout).
   To print the configuration page see the section above labeled
   "I.  INTRODUCTION" 

2. Open a DOS command window on your computer.

3. Type FTP [IP PRINTER ADDRESS] (for example,if the IP 
   address is 192.168.0.90, type FTP 192.168.0.90).

4. Press ENTER twice on the keyboard.

5. When prompted for user name and password,press ENTER for each.

6. Type "BIN" at the >prompt.

7. Press ENTER.

8. Type:put <path> where <path> is the location where the .RFU file 
   was downloaded from the Web. (For example, type:
   PUT C:\LJ4200\lj4200FW.RFU) and then press ENTER.

9. Once the download process begins and the firmware is updated on 
   the printer you can type "BYE" at the command prompt and then 
   press ENTER to exit the FTP session.


FOR UNIX SYSTEMS: 
-----------------
Any method that delivers the .RFU file to the 
printer will work, including: 

 $ cp /home/yourmachine/FILENAME /dev/parallel 

where /home/yourmachine/FILENAME contains the .RFU file. 


FOR MACINTOSH SYSTEMS:
----------------------

1. The first step in upgrading the LaserJet 4200/4300 firmware is 
   making sure you have the tools and files necessary for the 
   update. You will need the HP LaserJet Utility and the 
   xxxxxx.rfu file that you downloaded with this readme. 
   The rfu file is the actual firmware file for the LaserJet. 
   The HP LaserJet Utility is found on the software CD-ROM that
   was shipped in-box with your printer.  If you do not have 
   the software CD-ROM, you can obtain the HP LaserJet Utility by 
   going to www.hp.com on the world wide web and downloading the 
   latest installer for your LaserJet printer.

   Once you have the firmware file and the HP LaserJet Utility 
   you are ready to begin the upgrade process.
 
2. Launch the LaserJet Utility. (Attention Mac OS X users: 
   The HP LaserJet Utility is a Classic only application. 
   You must have a version of Mac OS 9 installed to use as 
   the Classic environment in order to launch the 
   HP LaserJet Utility.) 

3. Click on the Select Printer button and locate the printer you 
   would like to upgrade on the network. 

4. Once the printer is located select it on the right hand side of 
   the dialog and click OK. You will be presented with an
   information screen for your printer with some options on the left.
 
5. Select the button on the left side of the Utility that 
   says "Files".
 
6. You will get a dialog that allows you to select a file to be 
   downloaded to the printer. Click on the Select File button and 
   locate the xxxxxxxx.rfu file on your hard disk. 

7. Highlight the file by clicking on it and then click the "Select"
   button.  The Files dialog should then update by listing the 
   file you have selected in the "File to download" section. 

8. Click on the "Download" button. The Utility will then start 
   downloading the file to the printer. A progress bar across the 
   bottom will keep you updated on how much of the file has been 
   downloaded. While the file is downloading, the printer will display 
   a message stating "Receiving Upgrade".
 
9. Once the file is completely downloaded to the printer the display 
    on the LaserJet will show the message "Performing Upgrade". 

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

USING HP WEB JETADMIN TO UPGRADE THE FIRMWARE TO A SINGLE PRINTER 
------------------------------------------------------------------ 
This procedure requires that Web JetAdmin v. 6.5 or later is 
installed.  The following steps will upgrade a single printer 
through HP Web JetAdmin after downloading the .RFU file 
from the HP Web site.
