HP ENVY 4504 Not printing black ink even with full cartridge

[AG413]

The printer used by my office isn't printing any black ink. It doesn't say it has run out of black ink, but anything on a page I print that requires black ink is absent. I checked the cartridge to see if it had ran out and the printer wasn't telling me, but it had not. I also tried putting in a new black ink cartridge but it wouldn't print in black using that either.

There are no issues with printing in colour and the problem has only started today. The black cartridge is definitely compatible with this printer as it had been functioning with it correctly up until now.

We purchased this printer less than one year ago now.

So far aside from changing cartridges I have also turned the printer off and on again, but neither has helped.

I would greatly appreciate any assistance as we currently only have this one printer in the office and we rely on it for a lot of work.

Many thanks.

Additional Ink Cartridge Information after you have done all the HP recommendations:

Once you check the vents turn the cartridge over and check the underside near the ink opening.  They may be four plastic tabs near the opening that are raised up.  Make sure that these raised tabs are removed and made flush with the cartridge body.  This will cause the cartridge not to seat properly into the print head assembly possibly causing air to be drawn in.  This will especially affect the black ink cartridge.

Let us know especially if you find the above to be true.

Thanks! It seems to be working now as a result of cleaning the printhead.
