Updated February 21, 2017

Hewlett-Packard makes a variety of printers for home and office environments. HP Laserjet printers come with a number of security options, including a default user name and password that can be changed by the user. If you lose your password, you can still use all of the functions on your Laserjet 5550 printer by performing a reset to restore the printer to factory settings.

Turn off the printer.

Push and hold the "Go" button.

Turn the printer on while continuing to press the "Go" button until the "Attention LED" turns on. It should be between five and 15 seconds.

Release the "Go" button.


If the "Ready" LED turns on before you release the "Go" button, the reset will not work. Repeat the process beginning with Step 1.
