D-0313 error on C250i

[Labsy]

Hi,

Today I had one C250i with D-0313 error, where symptoms were:

- no operation could be performed, copy, scan, print, login via LAN...did not work

- upon restart printer landed in Service Diag screen, where ALL test passed OK. I also dig deeper into individual components test and went one by one and again, ALL tests were OK

- I tried to flash latest FW, but printer just skipped all 4 USB keys I tried with. So could not perform update.

What I did I changed Software DIP SW no. 163 to 00 to get rid of initial Diag menu, then switched it back to value 02.
From there on upon reboot it landed i user GUI screen, showing erroe D0313 again and offered me something like Restore to latest backup (or something like that).
Interesting, after this restore, all settings remained intact and everything works.

Any explanation?

Is this switch 163 in service manual and if not what is supposed to do?
D313 is TPM key data error and Restore is normal way to resolve it besides changing boards.

Hi,

I've got info about this Software DIP switch from local KM service, cannot find it in SM. What it does is to turn ON or OFF the auto-execution of Self-diag mode in case when the rank B/C trouble code is detected:
SW switch 163, value 00 HEX = Disabled
Value 02 HEX = Enabled (Self-diag menu will pop-up when B/C rank trouble code detected)
As this self-diag is actually in Service mode, this also means, that when mentioned trouble code is detected, printer will actually start in Service Mode when powered ON.

Regarding CD313 code, thank you, I accidentally had some luck with restore.

BTW...interesting is, that in Service Mode there is no way to see this error code, only in user-mode when powered on. That's why I used above mentioned software switch to turn service mode OFF, so I could see the actual error code on user screen.

Interesting, Thanks.
Next time try Counter - Service Call History (Data)
I have to test if it will display present trouble code.
How did you actually exit from self diagnostic to CE mode to change switch etc?

Oh, my bad...I've had photos of that, but somehow I missed that D313 code there, as I was only looking for DETAILS on right-side. I am It engineer, helping our printer specialists from time to time, so...lol, mistakes happen

Well, Self-Diag mode is actually within Service mode, so I just went END once to get to main Service menu, then to System 1 and changed Software DIP switch there, then reboot.

I had the same problem on a c250i. After 2-3 months the error was persistent and i had to replace the CPUB.
To replace the TPM Chip is useless!

Actually, we get quite a lot of notifications from C250i/C300i machines about E3-01, which is TPM probably, and most of those get resolved with power OFF/ON. But interesting, seems like too frequent issue.
BTW...why would a copier need TPM encryption? Confidential data?

TPM 1.2 is a international industrial standard.
Also, for example with scanning you will store user credentials from your nework on the MFP. There is no bad reason for a company to put atleast some security standards in place. You wont believe how easy it is to crack certain MFPs with certain firmware.
About a year ago, there was a security breach in newest HP MFP that made it possible to get the unencrypted password from users because the mfp was registered in the Windows AD Domain and logged in automatically.
