If the firmware update involves a change in the format of nonvolatile random-access memory
(NVRAM), any menu settings that are changed from the default settings will return to default
settings. The settings must be changed again if you want them to be different from the defaults.
Examples of settings that are affected in this way are tray types, default symbol sets, and Web-
access alerts.
The elapsed time for an update depends on the I/O transfer time, as well as the time that it takes
for the product to reinitialize. The I/O transfer time depends on a number of things, including the
speed of the host computer that is sending the update and the I/O method (parallel or network).
The reinitialization time depends on the specific hardware configuration of the product, such as
the number of EIO devices installed, the presence of external paper-handling devices, and the
amount of memory that is installed.
If the remote firmware update process is interrupted before the firmware is downloaded (while
RECEIVING UPGRADE appears on the control-panel display), the firmware file must be sent
again. If power is lost during the flash dual inline memory module (DIMM) update (while
PERFORMING UPGRADE appears on the control-panel display), the update is interrupted and
the message RESEND UPGRADE appears (in English only) on the control panel display. The
update must now be sent only by a computer that is attached to the parallel port of the product.
Finally, any print jobs that are ahead of the .RFU job in the queue are printed before the update
is processed.

3
In the address line of the browser, type ftp://<IPADDRESS>, where <IPADDRESS> is
the TCP/IP address for your product. For example, if the TCP/IP address is 192.168.0.90,
type FTP://192.168.0.90
4 Locate the downloaded .RFU file for the product.
5 Drag and drop the .RFU file onto the PORT1 icon in the browser window.
The product automatically turns off and then on again to activate the update. At the end of the
