I tend to stick to Epson, but H.P. is like the "Father" of printers, so good luck. I hope it uses Pigment ink! Sounds like the Black Cartridge Nozzle was partially blocked, and the blockage would block when the ink reached a certain point, depends on the nozzle design. Warm water flushed though the nozzle with a plastic hobby syringe, and piece of rubber tube that fits on the nipple the pieces the ink cartridge, Nozzle cleaner, (or a tiny drop of dish detergent in a larger bottle) shake, but not stirred, then put into a syringe, after being heated really war, almost hot, will clean out the nozzle, drip over everything else, and drive the ink to the bottom of the printer, where the rest of excess ink goes. I've kept my Epson WorkForce 1100 13" x 19" printer alive, and that printer when last available was almost $700 bucks. I paid $140.00 for it on a one day sale. I literally stole that printer, and it uses all Pigment Archival Ink. They all crap out at some point thought.
