"Printer Code not recognizeD"

HP Recommended
HP ENVY 4520
macOS 10.14 Mojave

I've followed the instructions to connect my printer - also restarted the connectivity - but every time I try the new claim code, it still says "printer code not recognized".

@jlai26, Welcome to the HP Support Community!


Let us try these steps to resolve this issue:


Make sure the printer is connected to the Internet.


Reset the printer

  1. With the printer turned on, disconnect the power cord from the rear of the printer.
  2. Wait at least 60 seconds.
  3. Reconnect the power cord to the rear of the printer.
  4. Turn ON the printer, if it does not automatically turn on.
  5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.
