You need to reinstall your printer.
If you have your installation CD do this:
Uninstall the old software -go to Start>Control Panel>install and uninstall>scroll down until you find your printer if it is still ther and click on uninstall.
Turn off the machine and unplug it
Turn off all your running programs including your virus control, using the icons on the lower right .
Restart your computer.
If you do not have the CD you can down load the driver at the manufacturers site. It will be www.(brand of your printer).com or you can google to find the correct site. Once there go to drivers and downloads and search for your printer model and op sys . Make sure that you choose the correct driver. Once you have located it, turn off all running programs, download it and SAVE it to your desktop. then click on it to install.
Follow all directions above just as if you had the CD.


Good Luck.

SOURCE: 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.

Error 906 for mfp t642


  1. Turn off the printer and let it sit for at least 10 minutes.
  2. Then power the printer back on.
    • If the error does not return, try printing a few print jobs. If the error still does not return, continue using the printer as before but keep an eye on it for the next few days. If the error does not return, it may have been an isolated incident.
    • If the error does return, you can perform an NVRAM reset on the printer. Note: Please do this only as a last resort before requesting service. Resetting the NVRAM on the printer will cause the printer to return all customer-defined settings to the factory defaults. To perform an NVRAM reset:
      1. Turn off the printer.
      2. With the printer still off, press and hold the following three buttons: Select, Go, and the right arrow (>) Menu button. All three of these are located on the printer's LCD screen.
      3. While holding the three buttons down, power on the printer.
      4. Continue holding these buttons until you see Performing Self Test, Clearing NVRAM, or Restoring Factory Defaults on the printer's LCD screen. You can then release the buttons.
      5. If the error does not return on power up, continue using the printer but keep an eye on it for the next week or two.
        • If the error does not come back, the printer should be fine.
        • If the error does return, the engine/system board will most likely need to be replaced.
