Digital BW, The Print

Hello, I am a new member and I wish to say hi to you all. I have an 
Epson 2200 printer that I am attempting to use MIS UT7 inks with. I 
also have an Epson 2200 dedicated to color printing. The UT7 inks are 
wonderful but, when the LM position from my initial purchase of 
cartridges ran out the replacement LM cart could not be recognized by 
the printer. A solid red light in the LM position comes on and stays 
on. I took the LM cart from the color printer and inserted it and the 
lights did a flashing dance back and forth and the printer came ready. 
When I put the UT7 LM cart back in I just get the solid red light. I 
have been in contact with MIS tech support for over a month now trying 
to get this fixed. I have reset the carts and printer many times, I 
have replaced the chip (new sent from MIS) and I have put another new 
LM cart in with no change in symptom. Have any of you had similar 
experiences that you have solved and if so will you please share the 
solution with me? Thanks, I am really keen on B&W printing and this is 
driving me nuts; I am on the verge of throwing out a couple of hundred 
dollars worth of UT7 ink.
