Bizhub c224e problem "Serial number must be entered" -> "TPM Chip has been changed"

[copier tech]

Since nobody has pointed it out, when you zap the SSD board you MUST enter the correct machine and type from the selection of the firmware stick or no firmware can be installed.

True, but if the machine has an error & you can’t enter CE you can’t perform this step.

I have had a rash of these at an college. The machines have been OFF since around May..many of the e series are giving this message..My tech support line is telling my tech if the reset tool doesn't work then they have to replace SSD and main board..and they want a NEW F'ing main board. No way..I'm just doing service swaps with any that can't get going with just the reset tool and a little bit of labor..Im about ready to send a few techs to advanced soldering school so they can replace these freaking batteries..Also, you may get replace drum/ITB messages as well. This is horrible. E

Interesting.

If the MFD is still plugged in & powered on at the wall there is no reason for the back up battery to go flat.

I couldn't agree more, however, I still have a large amount of these with batteries no longer holding the settings. And as the poster said, one of the reasons for this message is a dead battery. I'm sure some of these were left plugged into the wall as well. A lot of it is just old crap..were going on the 6th year lease as these guys dont want or can't afford to upgrade..and as it's CPC..no clicks means no charge..I just wish no clicks meant no service...E

These machines when new are left boxed up in a crate for months sometimes a year+ without an issue.

Maybe if they have been unplugged from the wall for a very long time the battery will go flat, never heard of this before.

I was just thinking that. I hope you chose the correct model number at the beginning of the firmware update process. =^..^=

I did that right. But thank you.

I don't know why but this winter we had more troubles then ever with drained batteries on different konica's (new/old no matter). But c224e is the first type which makes the replace so difficult.

Update:

I didn't fix first machine (c224e) after replacing battery, it's still shows "TPM Chip has been changed. Initialize tpm chip". I think I did a lot of different wrong combinations while trying to fix that without special firmware an without enough knowledge about that problem and how to repair it properly. I guess I will find some used MFPB with SSD and try to get it work.

I've managed to revive the second one (c364e).
1) Firstly I replaced a battery (it had 2.6 V )
2) After that I did a reset firmware 3 times in a row (A145FW)
3) Then installed a GHV-M1 firmware (it didn't install from first attempt "Download N.G.", the second attempt installed properly)
4) The last thing i did was entering Serial Numbers and turning on ADF/HDD etc. stuff)

The machine (c364e) has full functionality at this moment,but i didn't expect print/scan Counters to be zeroed, while Consumable life counters are ok.

Thank you guys for every information you provided me with.

Very useful information for me cause I am getting machines from wholesalers. Those machines by nature are a long time not connected to power.

Thanks!
