Digital BW, The Print

This is a copy of an email I sent to IJM last Monday.  I still 
haven't gotten a response from them and am wondering if anyone here 
can help me?  Please?!

"I am installing two CIS units using Piezotone inks on Epson 
1160's.  I installed the first CIS without difficulty and other than 
banding, it works correctly.  However, I attempted to install the 
second CIS and am having difficulty.  The tubing from the CIS seemed 
to be too short.  If the print head went all the way to the left, 
the line was pulled taut.  I moved the velcro part over and it was 
then too short to go all the way to the right.  In order to do 
further adjustment, I removed the cartridges from the printer.  The 
ink from two of the lines (the black cart and one of the color 
lines) flowed back into the bottles and the lines are now filled 
with air.  I have tried printing the flush image file twice but the 
ink in those two lines has not moved.  And the ink that does make it 
to the paper has a very heavy flow, puddling on the paper.

Is there a way to renew the vacuum and fill those two lines?  If 
not, how do I fill them with ink?  What is causing the puddling?"

Thanks for any advice you can offer.
