Fix ink cartridge
I had same problem. I must have ran the clean cycle more than 30-50 times over a period of days. That never made any difference. I was about to toss the whole thing but figured I would try one more thing. If it didn't work I would be in no worse shape. Here is what I did.
Took an almost empty black cartridge and inject a lot of 100% Acetone to dilute ink. Left some black in it since I didn't want to think it was empty. Inserted this cartridge and ran the cleaning a few time. IT WORKED. I used my word processor program and filled a page with large bold font characters and printed a page or two. Each page cleared more nozzles. After doing this cleaning/printing a number of time, I put in the full good cartridge. Ran the cleaning a few time to eject any of the Acetone diluted ink. Ran the printed page a few time to remove more of the diluted ink.
Everything seems to work now.
