PURPOSE OF THIS README FILE

This Readme file provides specific installation instructions and other information you should know before you perform a firmware upgrade for your CLJ3550 Series printer. Installation instructions are provided for Single Printer Upgrades.

This file provides specific installation and troubleshooting information. For additional information on the printer features, refer to the online user guide found on the Windows Printing System Installer CD-ROM that came with your printer.

WHAT IS INCLUDED IN A REMOTE FIRMWARE UPGRADE? The CLJ3550 Remote Firmware Upgrade file available from the hp web site contains firmware for the printer in one convenient download file. When the Remote Firmware Upgrade file is sent to the HP CLJ3550 printer the printer's firmware is upgraded.

WHO NEEDS THIS FIRMWARE?

Similar to Hewlett Packard providing improved software for your CLJ3550, Hewlett Packard will be providing firmware upgrades for your printer throughout its lifecycle. A firmware upgrade may be necessary if it is determined that you may benefit from an improvement that is documented below in section "III".

DETERMINING THE CURRENT LEVEL OF FIRMWARE

To determine the current level of firmware installed on the printer:
  1. Go to the printer control panel.
  2. Press the select button (the one with the check mark) to enter the menus.
  3. Press the up and down buttons to scroll to "INFORMATION" on the control panel display.
  4. Press the select button
  5. Press the up and down buttons to scroll to "PRINT CONFIGURATION" on the control panel display.
  6. Press the select button to print the Configuration Page.
  7. Look in the section marked "Printer Information" for the firmware date code. The firmware date code will look something like this:

    20030512 05.003.0
************************************
II. UPGRADE INSTRUCTIONS
************************************

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

UPGRADING THE NEW FIRMWARE TO A SINGLE DEVICE
---------------------------------------------------------------------

You can send an .RFU upgrade to a printer at any time via a network connection; the printer will wait for all I/O channels to become idle before cycling power. There is also a .exe upgrade for those with a USB connection.

NOTE: If the firmware upgrade 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 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 (USB or network). 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 \\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 printer is attached locally, then the .exe file can be used to download the file.

XXXXXXXXx format and example:XXXXXX

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

Change the timeout in the control panel
  1. Press 4 (Configure Device Menu)
  2. Press 5 (I/O menu)
  3. Press 1 (I/O Timeout setting)
  4. Enter 300 and press select (Sets timeout to 300 seconds)
  5. Press Resume/Start
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"

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

  2. Open a DOS command window on your computer.

  3. Type FTP <TCP/IP PRINTER ADDRESS>(for example,if the TCP/IP address is 192.168.0.90, type FTP 192.168.0.90)
