Cannot clean the printheads and the black ink won't print

[RSDFGFGDS]

My printer does not print black ink, I believe the problem in simply that the printhead needs cleaned because it hasn't been used in a while.

When I use that stupid HP Smart app to Clean Printheads the popup appears that says "Cleaning" but nothing else happens. The printer does not make any sound, and the popup does not go away. If I quit out of  HP Smart and try again then I get a different popup that says "Device is busy try again later" and that is all that happens.

I've tried doing the hard reset on the printer but it didn't make any difference. Is there a way for me to manually clean the printheads?

@RSDFGFGDS, Welcome to the HP Support Community! I’m here to help.

I see that the printer is not printing in black. yes, if the printer is not used for more than a couple of weeks, the ink could have dried up and needs cleaning.

I also see that you have tried the cleaning process via the HP Smart app but it was not successful as it got stuck.

As you have already tried a hard reset, unplug the power cable and hold the power button down for 10-15 seconds and release it. Power on the printer and check. 

Make sure the HP smart app is up to date. You may check for updates in App Store.
