Hello Roysk,
each Eeprom contains serialnumber and all counters in hidden memory areas.
Inside from system we have a serial data stream for all counters, serialnumbers and others..
If one component is broken, the data stream stucks and you get error code depended to the missing information.
Be informed about KYO Bulletin 2ND-0100 (I118) or UTAX Bulletin TB-65S
"Supply of EEPROM on the engine PWB described in the parts list (Newest version Rev.6 as of June 2018) will be discontinued."
This means: There is no more blank Eeprom for field service available!
If you ask Kyocera Europe, you can get new Eeprom, but you has to pay 50€ per pc.
As i know, from UTAX it`s for free!
Because of stored hidden system data, UTAX can duplicate the system informations into blank Eeprom only.
New blank Eeprom you can buy in UK for £0.63 don`t contains these important informations and maybe you will destroy your system in total...
Here you can see the IC2 structure for reading the data:

Mostly we have had similar problem in the field because of faulty RFID information from "faked" toners or bad connections/ missing data from any LLU part like ITB Eeprom, DK Eeprom, or else.
I agree with Giuboss regarding toners for checking at first.
Maybe you can share U000 maintenance report and eventlog txt files for checking the history.
