Re: Sadly, my 9950 ....

You may want to investigate deeper into the problem before you buy a replacement print head.

My i9950 was going fine until about March this year when the yellow and cyan channels were not printing. The printer service guy cleaned the print head and had got all colour channels going. But not for long, the yellow channel stopped printing again after half a dozen prints.

He asked me to put in a new print head. I did. This time, the first test print was fine. After that, the yellow channel has completely gone. I took the print head out and I could see the yellow ink flooding the printer nozzle but not printing on the paper. The printer still prints with the other 7 colours but without the yellow.

I suspect that the problem is with the printer control circuit. The service guy said that he was not able to fix that.
