Does anyone use MIS-UTFS in an Epson 9000? I'm having a number of 
issues, not the least of which is that my Y chanel will not unclog. 
I've had a repair guy in, he swaped out heads and did the maintnance 
kit thing but the clog persists even with the new heads! It seems 
fairly unlikely that the knew heads would have an identical defect as 
the old.
Has anyone had an issue with bad batches of ink from MIS causing this 
kined of problem? I would like to eliminate the ink as a posible 
culprate.
Any sugestions/advise (aside from getting a 9600)?
