Remote firmware update
The HP LaserJet 9050 printer 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.
The process for remotely upgrading firmware involves three steps:
1 Determine the current level of firmware that is installed on the HP LaserJet 9050 printer.
2 Go to the HP Web site and download the latest firmware to your 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. To print a configuration
page, follow these instructions.
1 Press the
SELECT
button (the one with the check mark) to open the menus.
2 Press the up and down buttons to scroll to INFORMATION, and then press the
SELECT
button.
3 Press the up and down buttons to scroll to PRINT CONFIGURATION.
4 Press the
SELECT
button to print the configuration page.
5 Look in the "Printer Information" section on the configuration page for the firmware date code.
The firmware date code looks something like this: 20031002 07.000.0.
Downloading the new firmware from the HP Web site
For support information about downloading new firmware from the Web, go to http://www.hp.com/
support/lj9050.
The product can receive an .RFU update to a product when the product is in a READY state. The
product waits for all of the I/O channels to become idle before performing the update.
NOTE If the firmware update involves a change in the format of nonvolatile random-access
memory (NVRAM), any menu settings that are changed from the default settings will return to
default settings. The settings must be changed again if you want them to be different from the
defaults. Examples of settings that are affected in this way are tray types, default symbol sets,
and Web-access alerts.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes for
the product to reinitialize. The I/O transfer time depends on a number of things, including the speed
of the host computer that is sending the update and the I/O method (parallel or network). The
reinitialization time depends on the specific hardware configuration of the product, such as the
number of EIO devices installed, the presence of external paper-handling devices, and the amount of
memory that is installed.
