Just a thought:  Why not take an old cart and cut off the top, remove the 
sponge, and cut off the outlet ports.  The cut up cart would hold the chip in 
position, and the tubes can go through the holes to the ink pipes.  This way, 
the cart can be withdrawn for chip resetting without removing the tubes.

A possible disadvantage to direct feed is that the carts filter the ink 
through the sponge and a small filter at the bottom of the cart on top of the 
outlet ports.  Without the filtering, clogs are more likely from contaminants 
in the ink.  Also, the sponge tends to control the ink pressure at the 
nozzles, reducing the likelihood of flooding the nozzles because of over 
pressure, and starvation due to under pressure, from the level of the inks in 
the bottles.
