error code cfb 31

If he had the panel apart he may have plugged the one connector into the wrong socket on the board. There is one connector that fits into an unused socket. Can't remember what the numbers were.

From another poster : "The solution for me was to put the connector CN8 to CN1 where it belongs to . That is what causes the C-code program loading. Nothing wrong with copier. Usually it happens when you replace the screen or touch panel. KM should have put different size connector for CN8 socket so there is no option for fault! -- Habik"

Yeah I've done this one too. I replaced a tablet, then CF-B31. I was just disgusted that I had done it to myself. =^..^=

I am not certain of this, but when you order the CODE DIMM I would assume that it's loaded with some base level of firmware, or the machine won't boot up. =^..^=

It . must work with usb flash I can buy it

I believe he was having touch screen issues, replaced touch screen, still had issues. Was asking for firmware and he apparently got it. Apparently ay 12% sounds like the machine was unplugged.
1. Never power off a machine while loading firmware.
2. Firmware version 2.45a was the last firmware for this series and was issued about five years ago.
3.It does not matter which USB port you use. The port at the operation panel is most convenient and it actually goes directly to the main board, it does not pass through the operation panel.
4. CFB31 is displayed when the operation panel and the main board are no longer communicating correctly and in this case I will assume that it is due to corrupt firmware.
that being said and the fact that this series does not have the ability to recover, like some of the newer models he may need to replace both firmware F-DIMMS.

Thanks........... have you the last firmware of km 4050 .....or where can i find it .... or buy the firmware .
