Lexmark E450DN - Error 950.10 NVRAM mismatch. How do I fix or reset?
The way that I have found to fix this problem is to replace the logic board but when you do that, this is where the NVRAM mismatch comes in. Once you change the logic you also have to change the display op panel. That is what is giving you this error. You must change logic and op panel at same time and it will not give that error.

I solved this problem: internal logic board NVRAM (eeprom 24c64) filled 0xFF.
The printer was initialized again by itself.
Unfortunately, I only read your solution today. Sorry! Can you tell me how I can write 0xFF to the NVRAM? Is that possible without disassembling the printer?
