Konica c250i frozen screen, errors C-D313, D3-8E

[jonbonse]

Hi all

So I'm having an issue with a c250i where the machine would show error C-D313, then reboot to ready however this keeps happening.

Error C-D313 is listed multiple times in the error log.

I have set the following power settings:
Power consumption in sleep mode: Disabled
Power save settings: Sleep
Enter powersave mode: Normal
Power Key - Sub power off (also tried low power mode)

Marketplace is hidden however just learnt it can be disabled with a SW?

The machine will come ready however eventually the screen will freeze and the control buttons on the display are unresponsive. Not even the control panel side power button.....The machine knows when the doors are opened though...as I can hear all the usual motors turning etc.

When the machine has rebooted, the control panel buttons are responsive however the side power button is not!

I tried to reflash the firmware with its current version GC2-Q8 but on the update screen, all show 'N.G' next to them before pressing 'Start' and won't let me reflash.

I have removed the CUPB and small SSD, cleaned the contacts with IPA.
I have set SW159 to Hex 08 which is supposed to make the HDD and the Fax board remain powered even after the Sub Power is turned OFF or the MFP shifts to the power save (Low Power/ Sleep) mode.

Now, I can hear a fan on constantly at the rear which I assume is related to SW159 however when I go back in to SW159 to put it back, the hex code is '00' which is what it started on.....

Error D3-8E now showed its face and keeps occurring every 20-30 minutes now!!

I would like to return to site with the very latest firmware. Can anyone confirm the latest is GC2-RE?

I would then try to update the firmware after a physical/logical format of the SSD. Failing this, if there is a reset tool to reset the machine to default settings?

Last resort would be a new CUPB and/or SSD...

I'm hopeful someone can confirm if I am on the right track?

Thanks in advance!

That error code is a TPM fault. It's that other little board next to the cpu board.

If it was me, I would try running the troubleshooter firmware to rule out issues with the SSD and CPU board since they are so common. If those come back good I would go after the TPM board.

In case you need it, attached is the page from the service manual.

Thank you!

Ill try source the troubleshooting firmware....

I believe Konica calls it diagnostic firmware or something to that effect. I forgot to mention, there are 2 versions. Get the newer of the two. The older version will mark newer boards (or maybe firmwares, can't remember) as bad erroneously. You are looking for something called AA2J0Y0-F000-GXX-34.

Turn on the device with the sub power button held down, then make a note of which of the 3 lights are flashing/static - that'll point you to the faulty board

I bet my money on CPU board, however use at first the diagnosis and recovery tool AA2J0Y0-F000-GXX-34.exe as Duplicator mentioned.

I bet it's a CPU board

[jonbonse]

Thanks all

I suspect the CPUB too as error D3-8E is nonvolatile data save error in the SPI-Flash which is in the CPUB 😭

[jonbonse]

Which leads me to the question of the part number.......

Konica have said the part number AA2JH02N06 for the CPUB is not been recognised yet I pulled it straight from the parts manual.....

[tsbservice]

AA2JH02N0L

UPDATE

First I would like to thank you guys for your input on this.

So I went back in and run the recovery tool, both SPI-Flash Check and SSD/MicroSD Check passed so I flashed the firmware with G00-RF and the printer has been fine since....

However I could not get function version to stay on 2.3. I chose hex 40 in sw25 but as soon as I rebooted the printer, I got as system error (no error code) and that the system will reboot. Once rebooted the function version went back to 1.

Anyway I didn't want to push my luck so left it on that and the printer is working, power button on control panel working again and the rear fan on when it suppose to be.

Left sleep mode off.

Thank s again!

[jonbonse]

Me again

So error D313 has returned!!

Not sure where to go from here as the recovery tool showed that both SPI-Flash Check and SSD/MicroSD Check passed..........

I had the customer click on 'Recover Data' from the error screen but they said it rebooted and came back to this error........

Firmware is on G00-RF.

Any more ideas?

TIA

Actually, I havent tried the TPM board as Duplicator mentioned so I will order one up!

If you print off the machine management list, look for code 0x1FFF/0x2201900000000100. if there is a large number of these it is the CPUB. These are CPUB codes.
