Take the memory board out of the main board and air dust the terminal. Clean the leads of the memory with 91% rubbing alcohol. Don't use anything less than 91% as it can cause damage. Let dry for about 5 minutes and reinstall. This will fix the issue in most cases. Make sure you unplug the printer and push the power button after it's unplugged and then wait 10 minutes before doing this.
