Tip & How-To about HP Officejet Pro X476dn Color Inkjet All-In-One Printer, Copier, Scanner, Fax

Resetting an OfficeJet X-series Printer

Since this printer has no physical buttons, but a touch screen display there is a special way to get into service mode

Right after applying the latest firmware upgrade on a brand new HP X476 printer, All of the admin functions displayed a padlock icon, they were locked and requested an admin password. Since I had just gotten the printer, got it networked, and all the preferences set, I had not created an admin password. The update assumes you had set it and locks all of the admin functions. So I had no password set, therefore there was no password after the update. So I could not do a reset as it is protected.
After over and hour with HP Support (his name was "Bob" with a very heavy Indian accent) I got them to "give up" the way to get into the service mode to do a hardware factory reset.
Warning: There are functions in this mode that are meant for service technicians and can cause major damage. We all like to "tinker" but I strongly suggest you stick to the reset functions only.
Start from the home menu on the printer's screen. Press the "return" icon. It is not illuminated at this point. You can display it by pressing one of the main icons (copy, scan, fax, apps) and mark where it is. Press it 4 times. The servfce menu appears. press down until you get the reset menu. Select the partial reset. That should reset the printer to factory defaults.

how can I reset my printer


After you have cleared the jam, make sure you
press the control panel back into place. You may also need to remove any jammed
paper from the rear access door or from inside the device.

F 56-2 ERROR CODE


Key Operator Mode
To the Key Operator
The key operator is trained to handle all special key operator functions that are not
accessible to the general user, such as monitoring overall copier activity, machine
performance, and service information; modifying machine settings; and controlling user
activity, for billing purposes.
A unique 4-digit key operator password is normally set by service at installation. If the
unique code is not set by service, the copier will not display Key Operator Password
Entry Screen when the Key Operator mode is being accessed, and a key operator
password will not be required. A service-set 8-digit ECM master key code must be
entered by the key operator to access the Electronic Copy Monitor functions, and a
service-set 4-digit Weekly timer master key code must be entered by the key operator to
access the Weekly timer functions.
To ensure the security of Key Operator mode, it is recommended that you establish a
unique key operator password, along with the key operator ECM master key code and
Weekly timer master key code, and keep them in a confidential file.

same issue here


Make sure the unit is in copy mode. Press '#' then the Interrupt key, the 'C' button, then the Interrupt key again (sequence #-Interrupt-C-Interrupt). This will put the copier into Service mode.

Enter the number 22, then press the Start key. Now enter the number 7 and again press the Start key. This will display the existing security code for key operator (special) settings.
