• There are two ways to update the firmware: One is by directly connecting with the main body using the USB memory device, and the other is by downloading over a network using the Internet ISW.

NOTE

• The settings in the "Utility" mode and the "Service Mode" will not be changed, when the firmware is updated.
• Activate the loadable device driver and voice data as required in the order shown below in accordance with the rewriting firmware or user's environment.
  1. [Service Mode] -> [System 2] -> [Install Data]
  2. [Service Mode] -> [System 2] -> [Driver Install]
  3. Turn OFF and ON the main power switch.

Confirming the firmware version

1. Call the Service Mode to the screen.
2. Select the [Firmware Version].
3. Check the current firmware version.
   NOTE
   • After conducting firmware updating, check the firmware version No. and confirm that the firmware has been normally updated.

System preparation

• PC with USB ports
• USB memory
  NOTE
  • Possible to be non-operational products.
  • USB flash memory compatible with the USB (1.1/2.0/3.0) interface. The speed is limited to USB2.0 specifications even if using a device that supports USB3.0.
  • The USB memory is formatted in FAT32 format.
  • No security functions such as encryption and password lock have been added (or the USB memory allows its security functions to be turned OFF).
  • A USB memory that is recognized by the computer as two or more drives cannot be used.
  • We recommend that you use a memory device with no more than 32 GB of capacity.

USB memory used to update firmware

1. Uncompress the firmware file.
2. Connect the USB memory to the PC, and copy the extracted data ''FW0006'' to the root directory of the USB memory.

NOTE

• More than one firmware data with a single model can be stored in the USB memory.
• In this case, copy the firmware data to the USB memory according to the following procedures.
  1. Make the folder named "FWSelect" (case-sensitive) to the root directory of the USB memory.
  2. Make a folder with any folder name (one byte alphameric characters, maximum 40 characters) under "FWSelect" folder, and store the firmware data to the folder.

Procedure

1. Turn OFF the main power switch.
2. Connect the USB memory containing the firmware into the USB port on the right side of the operation panel.
   NOTE
   • USB memory must be connected with the main power switch off.
3. Turn the main power switch ON while pressing the Stop key.
   NOTE
   • When [Administrator Settings] -> [Security Settings] -> [USB Connection Permission setting] -> [External Memory (Service)] -> [FW Update] is set to "Restrict", a message "It is limited by the administrator." will appear, and update of the firmware cannot be executed.
   • When [Administrator Settings] -> [Security Settings] -> [FW Update (USB) Perm. Sett.] is set to "Password Priority", it requires to input a password after confirming with the administrator.
4. Control panel shows F/W items to be updated, and select the particular type of F/W to be updated. (Select [YES].)
   

   F/W to be updated	Appropriate board	Remark
   MFP CONTROLLER	eMMC board (eMMC)
   SCANNER/PRINTER	MFP board (MFPB)
   FAX BOARD CONTROLLER1	Fax board/1 (FAXB/1)	Only when FK-517 is mounted

   NOTE
   • Unless one of the keys on the control panel is pressed, firmware is automatically updated after 30 seconds when the main power switch is turned on.
   • When the Boot Rom file is in the firmware data, [Boot Rom] key is displayed. Pressing the key updates data.
   • If either or both of the SCB file and power sub CPU file are contained within the firmware data, the [Other FW Update] key displays. Press the key to update.
   • When more than one firmware are stored in step 1, pressing [FW Data Select] enables selection. (Data of other models cannot be selected.) (At this time, the data marked with an asterisk on the upper-left side of the data selection screen is the firmware data in the ''FW0006'' folder in the USB memory device.)

5. Press the [Language Select].
6. On the Language Select screen, select a language to be displayed on the LCD area of the control panel, then touch [Fix].
   NOTE
   • The language selected on this screen is displayed on the Language Selection screen of Utility.

7. Touch [OK] to go back to the firmware update selection screen.
8. Press the [START]. (At this time, the Start key starts blinking red.)
   NOTE
   • The progress ratio of each board is displayed in writing the program.
9. Check that the control panel shows the message indicating that the data has been rewritten correctly ([Downloading Completed]). (The Start key lights blue.)
10. Turn OFF the main power switch.
11. Remove the USB memory.
12. Turn ON the main power switch.
13. Call the Service Mode to the screen.
14. Select the [Firmware Version].
15. Make sure if the version of firmware is updated.

Action when data transfer fails

• If “NG” appears on the control panel, indicating that rewriting has been unsuccessful (in which case the Start key lights up red), take the following steps.

1. Perform the data rewriting procedure again.
2. If the procedure is abnormally terminated, change the USB memory for a new one and try another rewriting sequence.
3. If the procedure is still abnormally terminated, change the board that has caused “NG” and carry out data rewriting procedure.
