Digital BW, The Print

I am trying to install a MIS CFS on my 1160 and have used the CFS 
Vacuum Pump to prime my carts.  Even after letting the carts sit for 
4 hours the sponges in the front of most of the color cart are not 
filled with ink, is this ok?  Above the inkjet port there seems to be 
plenty of ink.

thanks,

mark
