On mine I have to shim the right side under the heat bar that bolts to the carriage about the thickness of one sheet of paper to raise the right nozzle slightly. My guess is the carriage is just off on that side. Maybe it bowed down a bit - I don't know but it's just plastic so who knows. My right nozzle was just enough lower to catch once and a while on something. Shimming was the most suggested way to compensate. It has worked fine.
