I have a C364e that throws a C4091 error every couple of days. In the error history, it also shows CFA14 right after rebooting from the other code. I replaced the MFP board, but it started back up a couple of days later. Occasionally, it will stick at the logo screen when the customer reboots it (no idea if they're doing something wrong or not - I've never actually seen it happen). Any ideas?

HDD / firmware?

MFPB is on one part of this code, on another is PCRB as you know.
May be SSDB as well. I would perform an all data clear and SSDB format before replace other parts.

Use the SSD firmware reset tool and you should be good to go.

If you need the firmware make a small contribution to this site and will send it to you.

Also can be caused by the flat cable between the MFP board and PCRB pcb causing a communication issue. Try reseating that flat cable and inspect it for damage.
