Konica C368 Serial Number Error

Re: Konica C368 Serial Number Error

Valid serial numbers for
- Konica Minolta Bizhub C368 are A7PU021000001 - A7PU021027801 and A7PU021200001 - A7PU021210900
- Develop Ineo+368 are A7PU121000001 - A7PU121001990

Check label colour, should be more graphite, than black; and matte, not glossy - similar to the others.

Some machines you can buy 2nd hand, are sold without SN on the frame (sometimes fake, but matching the rest), with fake serial number and fake label on the back.
These machines come from KM contracts, and had been resold to third parties for scrapping.
However some scrappers break the agreement with Konica Minolta and re-market these machines with changed numbers, so that KM cannot easily identify the source.

In such case, you can't install i-Option licence.

Possible solution:
- you can check if there is original SN stored in upper EEPROM on PRCB (EEPROM DIP8 93C86, SN stored in reverse order, between 0x59A-0x5A6)
- the second place, you can take a look for SN is service chip under HV board (EEPROM 93C46, reverse order, between 0x70-0x7C)
- set original SN back in service mode, then ask (beg rather) politely someone with service manager account in LMS to generate initialization code for your original SN
* in your case, you can't use "alternative initialization code" that can be found on this forum, because it will not generate valid encryption keys for LMS

In case you can't extract original serial number, it's rather hopeless. In theory you could use any valid SN from above, but it's illegal.

Thank you very much for that information. I had a feeling that this where I was going to end up!

I really appreciate you taking the time to post this, I am happy to have a better understanding, learning everyday.

I have no intention of going the illegal route, so I'll see if I can extract the s/n.


Do I need a specific programmer to dump the EEPROM, is the process in the Service Manual?

Yes, you need universal programmer to dump EEPROM's. With the first one you shouldn't have a problem, but the second one is little bit harder.
Service chip EEPROM has SO8 package and is soldered to small PCB (about 1 inch by 1 inch), so you need to make interface cable, or desolder chip (but even desoldered cannot be connected directly to programmer).

Probably the best idea is to ask for dumping them both in the nearest mobile phone service

The process isn't described in the Service Manual.

Thanks again!

I have an old programmer ( somewhere ) so I'll start there, hopefully I dont have do the other, but
I'm sure I can rig something up

Re: Konica C368 Serial Number Error

If you print the consumables list from the control panel the serial number should be in the top right of the page.

Re: Konica C368 Serial Number Error

Update:

Managed to pull the original serial off the the EEPROM, ( BR93G86A ) So thats sorted
Now just need to find a way to have it initialized in LMS is that correct?

[jotunn]

Re: Konica C368 Serial Number Error

Yes, that's correct.

I would suggest asking people from the US for help about licence initialization.

Thanks for that, hopefully I can find someone that side of the pond to help


Do you know if it's possible to read the EEPROM on the C754e.

Re: Konica C368 Serial Number Error

if you have the correct serial number and the network settings reach the outside world then you should be able to activate it in web browser usage in admin mode

Thanks, I tried activating throught Admin / browser enable : validation failed

Service mode: error MAE001

LMS/activate: gives me a licence code, try to install it in service mode - invalid licence code.


I take it's activated in LMS / original serial number but not recognized on the MFP and needs a new initalization code for my s/n generated in LMS.

Is that correct?

The only place you can access is service chip hidden behind HV board - you need to craft some interface to access EEPROM.

...and needs a new initalization code for my s/n generated in LMS.

You can try "repair" in the meantime - [Service Mode]->[Stop][9]->[License Management]->[Repair] but I think, that the only solution is initialization.

Thanks, i hope its 8 pin or I'll be looking for another interface cable!

I'll try that anyhow , thanks.

Re: Konica C368 Serial Number Error

when a unit is decommissioned the sn is deleted from lms.
if your sn is not dead, the main body and scanner sn are used to confirm init id on this model.
these are input in service mode.

Re: Konica C368 Serial Number Error

The Repair option does show in Service mode, so I guess not!

I'll give that a try, thanks!
