Xerox D60327 User Manual

 

 

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.

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.
