Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Have you recently made any changes on the printer before the issue started?
• Did it happen recently after replacing the ink cartridges?
• Are you using genuine HP Ink cartridges or refilled cartridges?
• Have you tried to clean the ink cartridge contacts as well as the printhead?
• Are you able to make a copy from the printer?

While you respond to that, let's try these steps: 

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.

• Remove all the ink cartridges and then try to perform a hard reset on the printer.
• 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.
• Now insert the ink cartridges and then try to print a test page and check if it works.

Let’s first try and make a “photocopy” to determine whether the issue is with the printer or not. Place a document on the scanner glass and choose the “Copy” option. If the printer is making a good copy, then the printer hardware is fine.

If the copy comes out bad, this clearly indicates a possible hardware failure with the printer. Before you could contact our HP phone support for further assistance, I would suggest you follow these steps here:
