HP ENVY 4520 won't print black

@Jnenning,

 

Welcome to HP Support Community,

 

Are you using genuine HP Ink cartridges or refilled ink cartridges?

Have you tried to clean the ink cartridge contacts as well as clean the printhead automatically.

Have you tried to print the print quality diagnostic report and check for the defects.

 

Let's perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

 

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

 

Follow these steps to print a Print Quality Diagnostic report.

  1. Print a Print Quality Diagnostic report from the printer control panel, then evaluate the results.

  2. Make sure to load the input tray with plain, white paper.

  3. On the printer control panel, swipe the display to the left, and then touch Setup.

  4. Touch Tools.

  5. Swipe up on the display, and then touch Print Quality Report.

    A Print Quality Diagnostic report prints.

Evaluate the report for any defects. 

  • If there are defects found, try the steps mentioned in this document

Hope this answers your question.

Good luck and keep me posted about the developments. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue and give the post a Kudos for my efforts to help. Thank you and have a great week ahead. 🙂
