HP Envy 5540 won't print black ink

[MH01]

The printer will not print in black.  On the test page, it prints all the colors, even light and dark gray, but not black.  I've just replaced the cartridge and it shows a full one.  I've run all the diagnostics and they've come out fine.

   • If the print quality is unacceptable, touch Yes to perform the next level of cleaning.

Manually clean the area around the ink nozzles

1. Gather the following materials:

   • A clean, lint-free cloth, or any cloth that does not come apart or leave fibers

   • Distilled, filtered, or bottled water (tap water might damage the printer)

2. Turn on the printer.
