Epson S60600 Error Code 131B

[rdh3203]

I am unable to print on the Epson S60600 for more than a few minutes before the machine shuts down and gives me this error. (131B) See attached photo. Has anyone had luck finding a solution for this prior to calling a technician out? Any ideas of what I can try?
