Hi Paul,
I've just spent the better part of another day cleaning the head. I've removed the pump assembly so that I have total access to the head from the back. Lint free paper towels soaked with Windex(no ammonia) and still the strange nozzle check with what appears to be deflection, as I understand it. Since I hadn't been able to find the previous posts relating to this method for head cleaning, I thought I remembered that ammonia was a NO NO. Obviously I was mistaken. Today, Sue Williams, another member of this forum, dropped in and gave me a bottle of cleaner which I used in place of the Windex. However, as I mentioned in my original post, ALL of the MK nozzles are indeed firing, but NOT in the proper pattern. I talked with a tech today as well and might arrange a service call since it has both of us stumped. Or perhaps I'll just order a 7900 and be done with it. Keep this 7600 as a parts source for the PK version that's still printing as usual. Considering the vintage of this machine, I'm not sure I want to put any large amount of money into it now. It's been a GREAT printer and certainly owes me nothing, although I would like to get at least a few more months out of it if possible. It's going to cost about $800 to have a new head installed and that's a decent start on a 7900. Another decision I didn't want to have to deal with right now, but in business these things are seldom the result of good timing, as we all know.

Thanks for the input Paul. Much appreciated!
Gary

I've also used strips of paper towels to do this, but the bias tape is easier and is now one of the supplies I always keep around.  Any outlet that carries sewing supplies will have it.  I cut a strip long enough so that after the head is pulled over the soaded strip I can grab both ends of the tape and pull it back and forth acrross the bottom of the head.  Usually one cleaning cycle is needed after this procedure.
