Envy 7640 makes whining noise when printer is on but not in use

Envy 7640

My Envy 7640 makes a whining noise when the printer is on but not in use. Very annoying. Is there a solution? 

 

I've read posts that say replacing the power supply fixed the issue and another post that say replacing the power supply didn't fix the problem.

Hi @dnorris

Welcome to the HP Support Community. I'd be happy to assist you. Let us try these steps to resolve this issue:

 

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.
