I have changed the empty ink cartridges but each time I try to print, it tells me that they are empty and to go to hp.com/recycle. Again, the ink cartridges are brand new. I was able to go to the assistant and print a test page from the computer though and clean the heads.

You might try to reset the product. This would be similar to initializing the printer when new. (Suggest new cartridges for better odds of success).

Your control panel should have the following two buttons somewhere:

<OK> and <X> [might be <Cancel>]

1) Press and hold both <OK> and <X> until the printer powers off. Release the buttons

2) While pressing and holding the <OK> and <X> buttons, turn the printer power on. It should cycle for a short while, then turn itself off again.

3) Turn the printer on again using just the <On/Off>

This time, the printer will start an initializing routine that could take up to 5 minutes to complete. Please do not disturb it during this task.

Try printing again, or print a test page to verify results
