That is a fault in the start up procedure of the printer. Xerox calls it of all things PEST. Most of the time, it is a failure of the electronics module.
That is both difficult and expensive to replace. I am estimating for a new one, in the $1000 range from Xerox. A third party may be able to fix it for less, but that module is almost the entire electronics of the machine.
Wish I had an easier answer for you.

960 service memory error - a

The error indicates that the system board's on-board memory has failed. This usually requires a service call but you can try to turn off the printer, then turn on after 15 seconds. If the problem continues, I strongly suggest you contact Lexmark technical support or an authorized service provider for assistance. You may need to know your printer's model type and the serial number when calling for service. Thanks.

Before you replace the fuser, take it out and check for a piece of stuck label, paper, etc. You can spin the fuser roller by turning the gear on the side.
