Printer won’t print in black

[Maddie1313]

To whom this may concern, my HP Photo 7858 printer started printing in black and white with big white streaks. The color cartridge works fine. I went through all of the troubleshooting on the website yesterday and cleaned the cartridges 3 times. After the third time the printing diagnostic page had no black on it at all only color. I just printed a new print diagnostic page and it’s back to printing streaky and faded black ink where black ink is required. I really need to print some study

materials for this massive standardized test that I’m taking soon for grad school so I would appreciate any help any one could give me in a timely manner. I tried calling HP 3 times and the line hung up on me every time. I don’t know what else to do. I’ve attached photos of the 3 diagnostic pages that were printed after each cleaning and a photo of this black mass of ink that appears to be collecting under the print head which seemed abnormal to me.

Welcome to the HP Support Community.

This seems like a cartridge or a printer issue. If you have a new black ink, do try that.
