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.

Hi, I have a similar error (950.09 NVRAM[ONB]) on a Lexmark MS410. Can you tell me how I can fill the NVRAM with 0xFF. The Display shows the error but I can't go into the menu and the web-interface is down. Can you help me? Thank you very much!

I solved this problem: internal logic board NVRAM (eeprom 24c64) filled 0xFF.
The printer was initialized again by itself.

Nvram mismatched for t642 lexmark printer

Hello,

The NVRAM settings on the T642 could have been corrupted. You can try to restore the factory defaults by following the instructions in this article http://bit.ly/dn3wIC If that does not fix the problem you are probably looking at replacing maybe the System Board.

Error 950.10 NVRAM Mismatch. Replaced the LCD

If the lcd that you put in came from another printer instead of Lexmark, it will say that because the lcd, riser card on rip board and rip board all contain nvram that has to be matched. an lcd from Lexmark will no have any nvram data and the nvram will be copied from the other two sources upon install. The only way to get the lcd out of another machine is to get all of the above parts from the same printer at the same time.

This is a laser unit problem, probably being caused by the laser scanner motor being slow to spin up to speed, or having failed completely.

Replacement of the laser unit is the first thing to try here.
