OfficeJet 8600 Black Ink won't print

[nyrcritter]

I just received a HP OfficeJet 8600 Premium from my brother-in-law. It printed well when he had it. I plugged it in, turned it on and tried to print a simole text document. No black ink printed. I installed a new #950XL cartridge and tried to reprint. Still no black ink.I ran three levels of cleaning the print heads and still no black ink. I tried printing from two different laptops and my iPhone; still no black ink. The color cartidges work fine. Anyone know how i can fix this problem?

Dried ink gummed up the print head but you should use EWS to get more information about the cartridge

See if EWS can provide more information.

This link shows cleaning the 8600 printhead and removal is shown here.

This is another type of printhead cleaning, different from the above.

Cleaning and removing ink is shown below by our "Scullery" team.

An HP original video on how to clean the printheads by our experts. Yes, this can get messy, but it works. If your ink levels are good but you are printing blank pages then this is likely the solution.

Official HP advice on cleaning.

let me know which of these worked, if any.
