Remote firmware upgrade The process for upgrading MFP firmware involves three steps: 1 Determine the current level of firmware installed on the MFP. 2 Go to the http://www.hp.com/go/lj9000_firmware website and download the latest firmware. 3 See "Downloading the new firmware to the MFP" below to download the new firmware to the MFP. Downloading the new firmware to the MFP You can send a remote firmware upgrade (RFU) to the MFP at any time. The MFP waits for all input/ output channels to become idle before turning power off and back on. Note If the firmware upgrade involves a change in the format of NVRAM, the NVRAM settings will be lost and must be reset again by the customer.
Microsoft ® Windows ® systems Note Some Windows systems might require the following command to be performed at the command prompt if the system receives a “time out” error during the MFP firmware upgrade process: “mode lpt1:,,p” If the MFP is shared on a 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 computer from which the MFP is being shared, and PRINTERNAME is the MFP share name. If the MFP is connected locally, then the RFU file can be sent directly to the MFP with a copy command from a command prompt or MS-DOS ® window:
copy /b FILENAME PORTNAME where FILENAME is the name of the RFU file, and PORTNAME is the name of the appropriate print engine port (such as LPT 1). You can also send the file through an infrared receiver (IR) pod. UNIX ® systems Any method that delivers the RFU file to the MFP will work, including: $ cp /home/yourmachine/FILENAME /dev/parallel in which /home/yourmachine/FILENAME contains the RFU file. 52 Chapter 3 Product configuration C8523-90921
