Update The NIC Firmware
Your printer’s User Manual includes instructions for upgrading
the printer firmware. The process of upgrading the printer
firmware will automatically upgrade the NIC firmware to the
appropriate level.
IMPORTANT
The NIC firmware is updated only when the current printer
firmware is loaded via the network interface. The serial or
network interface may be used if the NIC adapter was
previously installed. Loading the printer firmware via the
printer’s parallel port will not update the NIC firmware.
CAUTION
Turning off the printer before the firmware update is complete
may permanently damage the NIC adapter.
Updating the printer firmware takes time. Please be patient
and wait for the “E-NET READY” message to display on the
LCD. Do not turn off the printer before it has completed the
firmware download procedure. The LCD will display
“ONLINE / E-NET READY” when the download is complete.
Wait for this message before turning off the printer.
