@MarB1, Welcome to the HP Support Community!
Are you using a Win PC or a MAC?
As this model printer does not have a touch-screen, you have to use this functions from a computer.
On this model printer, there is no option to clean the printhead. Instead, you will have to use Clean ink cartridges option.
Kindly refer to this documents to know how to clean and maintain your printer - Black Ink Not Printing and Other Print Quality Issues
Step 11 and 12 - Cleaning the ink cartridges
Step 7 - Align the printer
Hope this answers your query.
