Appendix B. Upgrading the Printer System Software

Upgrading Microcode Over Ethernet Networks
Use this section to upgrade printer microcode from a workstation or PC that is
connected to the printer over the Ethernet network. This section discusses
using the
lpr
command to submit the microcode upgrade to the printer.
Before you begin:
• Get the microcode upgrade file from the IBM World Wide Web home page.
See “To get the Microcode upgrade file” on page B–2.
• Make sure that you have a networked PC or workstation that can use the
lpr
command. Put the microcode upgrade file on this PC or workstation.
• Make sure that the printer is connected to the Ethernet network.
• Make sure that you have the TCP/IP address of the printer.
• Ask users to delay submitting print jobs to the printer until after you have
finished the microcode upgrade.
• Ask users to shut down Spooler and Downloader utilities sessions with the
printer.
To upgrade printer microcode over the Ethernet network:
1. Wait for the printer busy light to stop flashing and for the printer to reach a
ready state. This indicates that all jobs in the printer have finished
processing and printing and that all utilities sessions have been shut down.
Note: If the printer reaches a ready state but the busy light flashes
continuously, there is an open utilities session with the printer. Ask
your users to close all utilities sessions. If this is not possible, you
can still upgrade, but the process is less simple.
2. From the network-attached PC or workstation, open a DOS window or go
to an AIX or UNIX shell prompt.
3. Use the
lpr
command to submit the microcode upgrade file to the printer
as a PostScript job. For example, from Windows NT DOS, use the
command:
lpr -S serveraddress -Pibmcolor_direct filename
where
serveraddress
is the TCP/IP address of the printer and
filename
is the name of the microcode upgrade file. The TCP/IP name
of the Direct queue is always
ibmcolor_direct
. Either the Print or the
Hold queues will work equally well, as long as the specified queue is
enabled.
4. When the printer finishes receiving the file, the printer busy light begins to
flash. After the busy light stops flashing, press the Online push button to
take the printer offline.
Note: If, because of an open utilities session, the busy light never stops
flashing, wait 20 minutes to be sure the upgrade file is done
processing before pressing the Online push button. The printer
enters the offline pending state. If you think anyone may have
submitted additional jobs to the printer during the time when you
were waiting for the upgrade file to process, wait until you think
those files have finished processing. Then turn the printer off by
pressing the power button on the lower right front corner of the
printer, and go to step 6.
