There is a procedure for preparing the printer for transport that drains the lines.  Then doing an initial fill usually gets most of the color out.  I may have needed to do these steps twice with my old 7500.

I found cotton stuffing for chair cushions made a good & cheap substitute for the Epson material.

Did the printer have a good nozzle check before it was loaded?

I forget if that printer has 2 separate heads and pumps.  If so, the one for the light inks may be broken.

Both are risky with these old printers.  It think their value is about $0 now.  (I gave mine away.)  

Even if you get it running. agitating the Eboni/Carbon-6 could be a problem with OEM type carts.  The rubber seals of the 7500 carts will start to leak if the printer carts are taken out for agitation too often.  The 7600 and newer printers have much more robust valves that can tolerate the agitation.

On the positive side, the big old drops of the 7500 can make a very neutral -- even cool -- carbon print on Premier Art Smooth BW paper.
