Appendix C: Microcode upgrading

The PrintServer supports an online microcode upgrade facility permitting the installation of revised product microcode.

Operation of this facility will be possible via Psinst32 and the TCP/IP boot server.

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 C.1: Upgrading Microcode via Parallel port

The PrintServer microcode can be upgraded via the PAR1 port by using a PC containing the microcode in the shape of a file.

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

1.Power the printer OFF and connect a PC to the PARALLEL port using a centronics cable.

2.Power up the printer. When the session LED is lit, press the test key shortly.

3.When the printer generates a test page with the message: “..Awaiting microcode download”, the PrintServer is ready for download.

4.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

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

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