This is unproven. In my case, I didn't want to take chances, I had 
only one 1160 brand new in box left as backup. I never ran Piezo in 
it. When I switched to MIS, I switched to the backup 1160 as well.

You are descibing a terminal case of classic DSS I and others 
originally defined it. "Terminal" meaning it's about as bad off in 
tone as it will ever get.

I have found that putting Epson carts in for awhile and then returning 
old piezo ink to printer helped, but not completey eliminated problem. 
Someone else had better success with the direct injection method, but 
only with Fantastik, not Windex. They got 100% restoration of piezo 
density. So it might allow the MIS ink to work better too. You do run 
a risk of damaging your printhead. I guess if you do, you can always 
just have a new head installed by someone with the correct Epson tech 
software to do the alignments. If you want to buy a $10  injection kit 
that comes with enlarged tubing to fit over nozzle, MIS sells it. 
Don't try removing the head yourself.
