F-28-3 Error on Konica Minolta 7222?

I have a Konica Minolta 7222 - yes, an old bizhub. It was copying fine but i moved it out of my office and made the mistake of storing it in my garage. I assume the humidity messed it up. It has been in my house and away from the extreme humidity for about 4 months. I was hoping that getting it out of the humidity would solve it. Is there an easy fix or do I junk it?
