Remote firmware update
The HP Color LaserJet Enterprise CP4020-CP4520 Series product features remote firmware update
(RFU) capability. The method for downloading remote firmware updates from the Web site is similar to
that used to download the latest printing-system software and print drivers.
NOTE: Firmware for the embedded Jetdirect print server will update when the printer firmware is
updated.
The process for remotely upgrading firmware involves three steps:
1. Determine the current level of firmware that is installed on the product.
2. Go to the HP Web site and download the latest firmware to the computer.
3. Download the new firmware to the product.
Determining the current level of firmware
To determine the current level of firmware, view the configuration page.
On the printed Configuration Page, look in the section marked "Device (or Printer) Information" for the
firmware date code and version. It will look similar to this: 20090322 48.001.0
To print a configuration page, follow these instructions.
1. Press the menu button
to open the menus.
2. Press the up arrow
or the down arrow to scroll to INFORMATION, and then press OK.
3. Press the up arrow
or the down arrow to scroll to PRINT CONFIGURATION.
4. Press OK to print the configuration page.
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/cljcp4025_firmware or www.hp.com/go/cljcp4525_firmware
The .EXE file consists of a readme file and the .RFU file.
NOTE: For UNIX systems, the remote firmware update file is a .TAR file.
For Macintosh systems, the remote firmware update file is an .SIT, .DMG, or .ZIP file.
Downloading the new firmware to the product
For support information about downloading new firmware from the Web, go to:
