Engineering Details 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 selfextracting .EXE file. For detailed instructions about how to download the .EXE file, go to the following URL: www.hp.com/go/ljp3005_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. Downloading the new firmware to the device For support information about downloading new firmware from the Web, go to www.hp.com/support/ ljp3005. The device can receive an RFU update when the device is in a READY state. The device 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 device 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 device, such as the number of EIO devices installed, the presence of external paper-handling devices, and the amount of memory that is installed. Finally, any print jobs that are ahead of the RFU job in the queue are printed before the update is processed. Use one of the methods described in this manual to update the printer firmware.
