Try this... Press the Yellow reset botton then the number "1" then "0" then "8", don't hold them down, just push each botton once. Then hold down the "Stop/Clear" botton till the display changes to service mode, then turn the main Power Switch OFF then back On and see if it warm up.... If it dose not warm up you may have a problem with the fixing unit.... Good Luck

Are you sure of the code? I don't have the exact manual for that, machine but the number seems strange. "5xx" errors are usually related to the fuser, so could be a bad lamp, thermistor, or fuse. see note to reset (if there is not a problem) as follows:
There are 2 levels of service call conditions.
Level Definition Reset Procedure
To prevent the machine from being
damaged, the SC can only be reset by a
The copier cannot be operated at all.
Enter SP 5-810 (SC code reset) and
select “1”. Then hold down the Original
type key and the OK or ! key at the
same time (this does not require the
main switch to be turned off and on).

Service Fuser Error appears when the fuser does not warm to the required temperature. For this error on this Lexmark model T640n, the manual states you should power off the printer and power it back on, and if it is not plugged into a wall power point, change it to a power point mounted directly on the wall. Personally, I never got a Lexmark printer to work doing this, but this is in the manual. If this won't help, and the printer is under warranty, you should log it in with the servicing company.
If the printer is out of warranty, your next option is to change the fuser which costs around $350, so I think you would be better off getting a new printer unless you find a second hand one on Ebay.

That is a bad reading temperature of the Fuser Unit.
I will give same steps to unlock it.
Press yellow key
On the key pad press 1-0-7
Old the red key at least 3 sec
Press copy sp
Exit all the way out
Turn the machine Off / On.
This should be good. If doesn't work you have to call a technician to change some parts of the Fuser Unit like Hot Roller and thermistors.
Hope you understand.
