The only memory problem I know about is my own.........
But when you type that error into google it comes up with memory issues for other printers and such, so it has somthing to do with the CJ's built in DRam but I have never seen or heard another person with that issue on a printer.
Have you tried to power off and unplug the printer and press the power button to discharge any power left and then plug back in and turn back on. I don't think it will help but is worth at least a try.
Not sure if the battery that is in the printer could ever have anything to do with that error.
Sorry just stabbing in the dark..
