Upgrading Microcode over the Parallel Port
Use the instructions in this section to upgrade the microcode on your IBM
Network Color Printer using a parallel attachment. You are going to take the
printer offline, disconnect the printer from the Ethernet network, and bring the
printer online again to do the microcode upgrade.
Before you begin:
• Get the microcode upgrade file from the IBM WWW home page. See "To get
the Microcode upgrade file" on page B–2.
• Make sure that you have a PC or workstation parallel-attached to the printer.
• Ask your users to shut down open utilities sessions with the printer.
To upgrade printer microcode over the parallel port:
1. Press the printer Online push button to take the printer offline.
The printer may not go offline immediately:
• If the printer does not respond at all when you press the Online push
button, the printer is receiving a file. When the printer has finished
receiving the file, it will respond.
• If the display panel shows OFFLINE PENDING, the printer is
processing something or there is an open utility session.
2. Wait for the printer to go offline. If the busy light continues to flash and the
printer stays in the offline pending state, someone is probably connected
to the printer with a Spooler or Downloader. In this case, wait until you
believe that the printer has had enough time to finish receiving any job it
may have been receiving when you pressed the Online push button.
3. Once the printer has gone offline or you believe enough time has passed
since you pressed the Online push button for any file in transfer to finish
transferring, disconnect the Ethernet cable from the back of the printer.
Leave the parallel cable and power cables attached. If the printer was in an
offline pending state because of open utilities sessions, disconnecting the
Ethernet cable should allow it to go offline.
4. After the printer has gone offline, press the Online push button again to
bring the printer back online.
5. From the parallel-attached PC or workstation, open a DOS window.
command to submit the microcode upgrade file to the IBM
6. Use the
copy
Network Color Printer connected to the parallel port. For example, use the
command:
copy filename LPT1
where filename is the name of the microcode upgrade file and LPT1 is
the port to which the printer is connected.
7. When the printer finishes receiving the file, the printer busy light starts
flashing. The busy light flashes until the printer finishes processing the
upgrade file.
8. When busy light stops flashing and the printer returns to a ready state, take
the printer offline by pressing the Online push button.
9. When the printer goes offline, turn the printer off by pressing the power
button on the lower right front corner of the printer.
