Question about HP OfficeJet J4580 All-In-One Laser Printer
Please remove the power cable from the back of the printer.
Press and hold # and 3 while reconnecting the power cord to the product, and then release both buttons.
We have to press the keys on the printer. Release the buttons as soon as the power cable gets inserted to the printer.
