Jimenez,

I've botched the vacuum fill myself a couple of times and the bottom fill
method does the job just fine.

Don't worry about the air in the lines. Just go ahead and start printing.
The lines will fill up quickly and you will not harm the printer. As you
print or do a nozzle check you should see the air in the lines move as ink
flows from the bottles.

Happy printing!

Martin, & everyone else,

I am not a big fan of the vacuum fill method myself.  I am going to 
redo my CFSs using the bottom fill method.
Opinions on the "perfect" amount of ink to put into the cartridge 
(epson 1280/90).  I have come to realize that there has to be just 
the right amount, not too much (no vacuum break) and not too little 
(I think this contributes to sponge/ink foam).
MIS has recently told me 18cc is the ideal amount.  Just looking for 
other people's opinions.

All the best
Kevin

Addendum, to my post.  Using the botom fill method the hoses will be 
empty, so upon "charging" the carts once installed, a hose length of 
air will go into the cartridge.  I guesstimate a hose length for a 
1280/90 to be about 2cc of volume.
I would really love to have a confident idea of how much ink Epson 
puts into their OEM cartridges, because every CFS I have made 
from "parts" using Epson OEM carts works perfect, every time.  This 
install of a CFS includes allowing for one hose length of air going 
into the cartridges.

Thanks, & sorry for the split post.

Kevin
