Xerox 4500 PS TR instruction manual Appendix B.2 Upgrading Microcode via TCP/IP Boot Server

Appendix Section

Xerox 4500 PS TR

NOTE:

If you are making use of printer drivers in connection with your PC's centronics port, it is important that these drivers are temporarily disabled while you perform

the actual microcode download using the "copy"-command. Otherwise the printer drivers may interfere in the microcode

image sent to the Xerox 4500 PS TR implying serious problems. You should use a generic/text printer driver when running Windows environment and IBM NULL when running in OS/2.

6.Pay attention to the LED's on the Xerox 4500 PS TR front-panel. These will now blink very quickly - one after the other. This is an indication of the microcode download taking place.

7.After the download process (time will depend on the PC’s hardware) the “PRT” LED will stay lit. The remaining LEDs will be off.

8.Your Xerox 4500 PS TR has now been equipped with a new microcode.

9.Power the Xerox 4500 PS TR printer off and back on for the new microcode to become effective.

10.Press the test key in order to verify the new microcode level stated on the test printout page.

Appendix B.2: Upgrading Microcode via TCP/IP Boot Server

The microcode can be downloaded to the Xerox 4500 PS TR using the TCP/IP protocol TFTP:

1.Customising the BOOTP server data base access file (BOOTPTAB file entry for the device with a bootfile parameter).

2.Customising the bootfile entry (customising the bootfile to indicate the path to the microcode).

3.Power the printer off/on.

4.Validate the update microcode.
