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?
