HOW DO I FIX A SYSTEM SUPPLY ERROR

[JDECORTE]

WHEN I CHANGED MY BLACK INK CARTRIDGE I GOT AN ERROR MESSAGE SAYING SYSTEM SUPPLY ERROR.  IT WAS WORKING PERFECTLY F INE BEFORE I CHANGED THE INK CARTRIDGE.  I TRIED A NEW INK CARTRIDGE THINKING THERE WAS SOMETHING WRONG WITH THE ONE I USED BUT DID NOT FIX THE ISSUE.  I'VE ALSO UNPLUGGED THE UNIT FROM POWER AND THE COMPUTER AND STARTED IT BACK UP, BUT NO CHANGE.

Hi @JDECORTE,

Welcome to the HP Support Community

I understand you are getting an error message  HP OfficeJet Pro 8720 Ink System Failure on your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Are you using genuine HP ink cartridges?
• Was there any recent update on the printer prior to the issue?
• Was there any paper jam or carriage jam issue on the printer recently?

While you respond to that, Let's perform a power drain: 

• 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 (This is important) 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
