Unlike other machines with removable EPROM (Erasable Programmable ROM), this machine is equipped
with a F-ROM (Flash ROM) and an IEEE1284 Parallel Port as standard. The F-ROM offers the flexibility of
quick and easy firmware updates. The firmware of the machine can be updated with the removable F-ROM
Card or with a PC via the Parallel Port of the unit. (Refer to Section 5.1.9)
The following is the basic procedure to update the firmware of the machine. The details are described in the
Firmware Update Tool Operating Instructions.

1. Install the Firmware Update Tool.
2. Install a Flash Memory Card (2MB or higher) into the machine.
3. Follow the instructions included in the Firmware Update Tool Operating Instructions.

1. Unplug the Power Cord to turn the machine OFF.
2. Install a Flash Memory Card (2 MB or higher) into the machine with the Panasonic Logo 

facing outwards.

3. Plug in the Power Cord to turn the machine ON.
4. Perform the Service Mode 9-2 (Firmware Backup).
5. The firmware is copied into the Flash Memory Card.
6. After the backup is completed, press "STOP" to return to standby.
7. Unplug the Power Cord to turn the machine OFF.
8. Remove the Master Firmware Card that you just created from the machine.
9. Plug in the Power Cord to turn the machine ON.

10. Use this Master Firmware Card to update the firmware on other machines.

1. If a Master Firmware Card is created containing UF-790 Firmware Code (V1.04 Only), 

ONLY a UF-790 machine can be used to delete the Firmware Code on the Flash Card.

2. If a Master Firmware Card containing UF-790 Firmware (V1.04 Only) is installed in a 

previous model (i.e. DP-130P/135P/135FP/150P/150FX/2000/2500/3000, DX-2000, 
UF-585/595/885/890/895) when the power to the machine is turned on, the machine will 
not boot-up at all.

1. Before starting, print the Fax and Function Parameter Lists.
2. Unplug the Power Cord to turn the machine OFF.
3. Install the appropriate Master Firmware Card into the machine with the Panasonic Logo 

facing outwards.

4. Plug in the Power Cord to turn the machine ON.

5a. Perform the Service Mode 9-1-1 (Firmware Update) (UF-590/790/6000/6100).
5b. Perform the Service Mode 9-1 (Firmware Update) (UF-580/780/5100).

6. The firmware is copied into the machine.
7. After the update is completed, the machine reboots itself and returns to standby.
8. Perform the Service Mode 6 (Parameter Initialization).
9. Unplug the Power Cord to turn the machine OFF.

10. Remove the Master Firmware Card from the machine.
11. Plug in the Power Cord to turn the machine ON.
12. Reprogram the Fax and/or Function Parameters according to the lists printed in Step 1 

above if the settings are other than factory default.

For a UF-790 with Firmware V1.04 and updating the Firmware to V2.xx, 
please see Section 3.4.7. for Instructions.
