Appendix B: Microcode upgrading

The Xerox 4500 PS TR supports an online microcode upgrade facility permitting the installation of revised product microcode.

Operation of this facility will be possible in the following ways:

1.Via the TCP/IP boot server

2.Via the centronics port

CAUTION:

∙During the initial 20-30 seconds after the microcode download, a failure (power off) will have fatal consequences, because the code will be lost and the previously stored code erased. If this happens, a basic code still remains in the flash to allow redownload of code. But download can then only take place via the parallel port.

∙You must always connect printer to PARALLEL port.

Appendix B.1: Upgrading microcode via Parallel port

The Xerox 4500 PS TR microcode can be upgraded via the PAR1 port by using a PC containing the microcode in the form of a file.

To download the microcode via the parallel port follow these guidelines:

1.Power printer off.

2.Connect a PC to the parallel port using a centronics cable.

3.Power up the printer. When the session LED is lit, press the TEST key shortly.

4.When the printer generate a test page with the message: “xxx 5108 Awaiting microcode download”, the Xerox 4500 PS TR is ready for microcode download.

5.Type the following command at the PC's command-prompt : "copy 0xxxxx.B80 lpt1 /b"

where "0xxxxx.B80" is an example of a firmware file.1

1The suffix .B80 may be case sensitive depending on the operating system.
