Hi @Shirley28,

Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here? Learn How to Post and More.

As I understand you are getting an error message on the printer screen and you are having issues printing on your HP Photosmart 7520 printer. Don't worry as I have a few steps which should help you resolve your issue.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the printer before the issue started?

Are you using genuine HP ink cartridges or refilled cartridges?

Have you tried to clean the cartridge contacts as well as the rollers?

In the meantime, let's start off by performing 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.

Please follow the steps suggested in the support document for - 'Missing or Failed Printhead' Displays for HP Photosmart 7520 e-All-in-One Printer Series

If the issue persists, I would suggest the next step would be to try and replace the printhead and then check if that helps.

If the issue persists even after replacing the printhead, I would personally suggest this could be a printer hardware. I would recommend you contact our HP phone support for available service options. Even though your printer is out of warranty, you might be able to get some good upgrade options if possible. Hence I would advise you call HP phone support or go for a new printer.
