Thanks very much. I did try the pwerful cleaning cycle a half dozen times; no help. indeed before one cleaning cycle on LLK/Y the cyan jet worked fine. When I did the next nozel check print after the cyan jet was completely out.
I have turned the printer on and off many times over 2 weeks and done many cleanings all to no avail. I have had a lot of trouble with LLK since the beginning.
I will try and clean the print head myself. If it doesn't work I will likely buy a new one (with 3 year extended warranty).
Do not settle for mediocrity. Rather strive for excellence for even in that attempt lies a measure of success.
