(2) Updating the firmware on the fax control PCB (Compact Flash card)

To carry out a FLASH ROM firmware update of the fax control PCB, follow the steps below.
This firmware update requires the following tools:
CF jig (P/N 3CM6803*)
Compact Flash card (Products manufactured by SANDISK are recommended.)
Caution:
• Turn the main power switch off and disconnect the power plug from the wall outlet before disconnecting or inserting
connectors.
• When writing data to Compact Flash card from a computer, be sure to format it in advance.
(For formatting, insert a Compact Flash card and select a drive.)
• For a desktop computer, connect a Compact Flash card reader/writer to it. For a notebook computer, use a PC card
adapter or a connection portion only for Compact Flash card.
<Procedure>
1. Check the current ROM version using maintenance mode U680.
2. Turn the main switch off and disconnect the power plug from the wall outlet.
3. Remove the rear cover and the control-box cover. (Refer to"(1) Updating the firmware on the fax control PCB (Flash
ROM)", Steps 1 to 3, above.)
4. If you are using a new CF jig, continue as follows to write the boot program into the jig's flash boot. If your CF jig
already has the boot program in its flash boot, jump ahead to step 13.
5. Insert a Compact Flash card containing the boot
program into the CF jig. Be sure that the card fits in
smoothly along the left and right guides. (Trying to
force the card in incorrectly may cause electrical
contacts to break.)
6. Set dip-switch bit SW012 on the jig to "MEMORY".
7. Connect CN1 on the CF jig to CN5 on the fax control PCB.
8. Plug the machine's power plug back into the wall outlet, and turn the main switch on.
9. Run maintenance mode U881 ("Load program to jig") to write the boot program into the jig. (See page 1-3-36.)
10. When loading terminates normally, disconnect the power plug from the wall outlet again.
11. Disconnect the CF jig from the fax control PCB.
12. Remove the Compact Flash card from the CF jig.
13. Insert a Compact Flash card containing the firmware
into the CF jig. Again, be sure that the card fits in
smoothly along the left and right guides. (Trying to
force the card may cause contacts to break.)
14. Set dip-switch bit SW012 on the jig to "BOOT".15.
Connect CN1 on the CF jig to CN5 on the fax control
PCB.
