Black print will not print

[HSF]

I have loaded four new 364 print cartridges and cleaned then aligned the print heads via the printer instructions but black will still not print and I can't take out the printer head as it has no release clip. Any help appreciated  or do I need to buy a new printer? Thank you

Hi @HSF,

If you have already performed the steps from the document Black or Color Ink Not Printing, Other Print Quality Issues and the issue persists, it could be a hardware failure.

Please reach out to the HP Support in your region regarding the service options for your printer.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile name, you should see a little blue envelope, please click on it. 

Hope this helps!

I have the same problem with two HP printers.  I have cleaned the heads, and went through all the process to get it to print.  It will print all the colors but black.  I am wondering if it has something to do with me downloading a Adobe Reader program. The printer was working fine before that.  Any thoughts about that.  I have a Dell computer that is only 1 1/2 year old.
