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

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.

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.
