Digital BW, The Print

I have a C84 that I've been using with MIS EZ Inks and a (CFS) 
continuious flow system. Today, while printing, the printer 
stopped in the middle of a print and both red lights began to 
flash. When the two red lights are flashing, the manual says to 
clear any paper jams. There were none except for the partially 
printed print which ejected easily. The lights are still flashing. 
The next step in the manual says to call for help. 

Has anyone had a similar problem? Am I going to have to send 
the printer in to be fixed? Could the CFS have contributed to the 
problem? It's been working fine until today.

Any help or suggestions before I call Epson?

Thanks,

Scott
