Hi @Bob057110,

Welcome to the HP Support Community

I understand you are getting an error message Ox61000072 on your HP ENVY 4520 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Was there any Paper Jam / Carriage Jam prior to the issue?
• Are you able to move the carriage manually?
• Are you able to remove inks?
• Did you install any inks 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
