where <FILENAME> is the name of the .rfu file (including the path) and <PORTNAME> is the

name of the appropriate printer port (such as LPT1). For example, C:\>copy/b c:\9500fw.rfu lpt1

Note

If the file name or path includes a space, you must enclose the file name or path in quotation marks.

For example, type C:\>copy/b "c:\My Documents\9500fw.rfu" lpt1

Print a configuration page and verify that the firmware revision number matches the revision of

the current upgrade.

Type the word “exit” at the command prompt to close the command window.

Windows NT 4.0, Windows 2000, Windows XP, or Windows Server 2003

The .rfu file can be sent directly to the printer by typing a copy command at a command prompt or in

an MS-DOS window.

At a command prompt, type:

copy /b <FILENAME> <PORTNAME>

where <FILENAME> is the name of the .rfu file (including the path) and <PORTNAME> is the

name of the appropriate printer port (such as LPT1). For example, C:\>copy/b c:\9500fw.rfu lpt1

Remote firmware update through a Windows network

If the printer is shared on a Windows network, follow these instructions.

From a command prompt or in an MS-DOS window, type:

copy /B <FILENAME> \\<COMPUTERNAME>\<SHARENAME>

where <FILENAME> is the name of the .rfu file (including the path), <COMPUTERNAME> is the

name of the computer from which the printer is being shared, and <SHARENAME> is the printer

share name. For example, C:\>copy /B c:\9500fw.rfu \\your_server\your_computer

Note

If the file name or path includes a space, you must enclose the file name or path in quotation marks.

For example, type C:\>copy/b "c:\My Documents\9500fw.rfu" \\your_server\your_computer

Press

Remote firmware update for UNIX systems

For UNIX systems, any command method that delivers the .rfu file to the printer is acceptable,

including the following:

At the command prompt, type:

$cp </home/yourmachine/FILENAME/dev/parallel>

where </home/yourmachine/FILENAME> contains the .rfu file.
