TPM boards are also used in laptops. I have some more epeerience with TPM in these : Unless you replace a mainboard with a new one (you have to program/brand the serialno in them) you cannot use the TPM on another board. It's a securety measure to stop ppl from pulling data from parts of a system.

In the case of laptops : TPM + Mainboard + Disk -> replace either and data is inaccesable...

I guess if he printer is new and setup worked fine... maybe the TPM went bad ?

u can't swap Main pcb 1's -------poster created the E355-0004 code/ and E748-9000----level 3 will not clear the code with mismatch Main Pcb 1's

MNCON 1s are of different engine speeds between 6065 and 6075 and use different part numbers.

When you need to replace the Main Controller PCB 1, it is important to first ensure the proper model number of the device as the Controllers are different for each model.
