Hi,
I was able to data log the communication from the toner chip to printer.
During power on the chip sends about 155x5bytes.
Most of them are similar except for only five 5 byte streams.
For example during 9 consequetive power on one five byte stream changes this way.
CB 51 06 6F 76
CB 51 40 07 C0
CB 50 44 27 F8
CB 51 40 2E 3A
CB 50 46 0E F8
CB 50 42 26 F6
CB 51 46 27 90
CB 50 40 4E 84
CB 51 44 4F E2
The change is vague. Could it be encrypted.
Any advice on what could be hidden?
Regards,
Sibi
