Digital BW, The Print

I have been working on the Epson 7000 CIS for a few days now and have 
developed what I think is the final prototype. It is a hybrid cross 
between the MIS and BIS designs.

So far, I am not getting any air infiltration, but this thing really 
need to cook for 2-3 weeks before I proclain it a success.

Here is what I did differently,

1. Increased tubing sixe from 1/16" I.D. in the MIS stsem to 3/16" 
I.D.

2. Removed the "shock tube" design and instituted a "straight 
through" path. 

3. Added small stainless steel hose clamps to secure the tubing to 
the cartridge nib after sealing connection with clear silicone 
sealant to provide additional insurance against air infiltration.

If anyone wants to see pictures, email me and I will forward them to 
you.
