Hi Tom,

I've been following your posts regarding the problem you're having 
with the clear spongless carts and wanted to offer some support:

1. Since you were getting a "promising" nozzle check at one point but 
then but cleaning cycles made things worse, it sounds like the 
problem is ink starvation to the head

2. If you had "bad plugs" you would get an opposite problem as Ken 
pointed out -- probably too much ink flowing and leaving "blobs" on 
your prints. Still, make sure they're seated properly and taped if 
necessary

3. Although you pulled the vent tab covers off, make sure that the 
vent holes are actually open. If in doubt, use a thin needle and pass 
it through the vent hole -- sometimes adhesive from the tab or 
manufacturing debris can block the hole and prevent venting, which in 
turn prevents ink from being drawn from the cart

Here's a quote from the MIS forum about this problem:

"In some cases the user did not pull the yellow tab on the cart to 
open the air vents. The cart will not print if the tab is not pulled. 
This is on the top of the cart, not bottom.

In some cases, the air vents did not open when the tab was pulled. 
Making a pin hole puncture into each chamber thru the top clear 
surface will let air in to vent the cart, or return it to MIS for an 
exchange.

We have sold thousands of these spongeless carts, and have had less 
than 20 complaints."

4. Last thought -- since at one point you mentioned that you were 
having problems with the printer recognizing the cart, there may be a 
QC issue with the cart causing that problem and also the ink flow 
issue. Some of the early carts did have chip problems, but MIS is 
very good about replacing any defective products

Hope this helps. Short version: Make sure the plugs are well sealed 
and the cart vents are open so it can "breathe" and all the ink 
channels are primed -- if that doesn't do it, I'd ask MIS for 
replacements rather than abandoning the effort...

Cheers!
Richard
