Black ink not printing.  New cartridge installed, ran tests, performed hard start and still no black. Cant run a print quality report because the printed wording is alas, only in black which is a problem because:  Black ink not printing.  Printer was not plugged into a surge protected outlet and there was a power outage locally.  But color still works great.

Even though Ive cleaned printhead multiple times, doing it multiple times in a row allowed my magenta ink to flow again.  Thanks
