Digital BW, The Print

I put windex on the pad yesterday and left it overnight.  There is 
some improvement, but the "yellow" ink is still badly clogged and 
some of the others show problems during a nozzle check.  The wierd 
thing is that the nozzle pattern got worse after running a cleaning 
cycle.  I have just put a second application of windex on the pad.  

If this does not do it, what is the next step.  I have found two in 
various places:  1) remove the carts and squirt windex directly into 
the "feed tubes;" or 2) reinstall original Epson carts and see if 
that cleans things out.  Unfortunately my orignal Epson carts have 
been sitting for almost a year, so that means I would have to buy at 
least the color cart, as the black seems fine.

I really can't complain since this is the first time since I swiched 
to quad inks last October that I have had a serious problem.

Any help appreciated.
