HP LaserJet Pro M12w Factory Reset

[SlowFox1]

Hello All,

I have made a mistake while configuring the wireless network, configured the wrong gateway. Therefore the Printer has an ip address and a subnetmask but the wrong gateway. Therefore it is not reachable trough the Embedded Web Server. I need to do a factory reset, to get back to scratch and reconfigure the network.

When the selftest/configuration page is printed I see that is configured for the Wireless network, (192.168.0.50/255.255.255.0 with gateway 192.168.1.20 the gateway should be 192.168.0.1)

What I have done:

The Factory reset option in the manual (Page 48) doesn't work:

HP LaserJet Pro M12w Manual

1. Open the HP Embedded Web Server (EWS): Network-connected printers <- Due to bad gateway printer is not reachable!

a. Print a configuration page to determine the IP address or host name. <-Possible

i. Press and hold the Cancel button until the Ready light begins blinking.

ii. Release the Cancel button.

b. Open a web browser, and in the address line, type the IP address or host name exactly as it displays on the printer configuration page.<-From here it doesn't work

Press the Enter key on the computer keyboard. The EWS opens.

NOTE: If the web browser displays a message indicating that accessing the website might not be safe, select the option to continue to the website. Accessing this website will not harm the computer.

2. Click the Settings tab.

3. Select the Restore Factory Settings option, and click the Apply button. The printer automatically restarts.

The solution on the HP support page doesn't work either:

Pressing the Cancel button for hours doesn't Factory Reset the Printer.

At this moment the workaround is to print by USB cabel.

Who can give me the correct clue to correct solution!

Kind Regards

Zoran

Do a Google search to reset your printer to factory defaults.  I had the same problem, and found the solution for my printer to be a 2-fingered reset of holding down the left and recall buttons while powering-on the printer.  I have a printer with a 2-line display, so I do not know if that would work for you.

Hello TonyK

The option regarding to do a Google Search . that I have done.

I have tried several different combinations already. PowerUP and holding the Cancel button, PowerUP and holding other buttons. None of them helped. I need a real factory reset solution with the keys on the printer.

Kin regards

*** The SOLUTION ***

The solution was is:

1: Turn Off Printer

2: Turn On Printer

     - but hold BOTH buttons on the Printer: The Red X (Cancel) and the WPS button, untill you see the lights flashing!

Then the printer spits out a new Configuration Page out with 0.0.0.0/0.0.0.0 as IP address and Subnetmask.

Then you can use the HP software to reconfigre the Printer!
