Factory Reset for HP Office jet Pro 7740

[6FeetUnder]

Had to get a new Router, so new network name and password.  I had the printer set to fixed IP address on the old network.  Now it won't connect to the new network, I can't get it on the web server.  When I try to reset the printer from its control panel it says the person who set up the printer (that's me) blocked the function.  HELP!!! I can't communicate with my printer to tell it to use the new network.  REALLY NEED HELP here..

Hi @6FeetUnder,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I came across your post and wanted to assist you. I see from the post that you are having an issue after replacing the router. Don't worry as I have a few steps to help you get through this concern,

Let's start off by performing a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

Next thing, I would suggest here is to perform printer to the original network settings

1. From the printer control panel, touch or swipe down the tab at the top of the screen to open the Dashboard, and then touch ( Setup ).

2. Touch Network Setup.

3. Touch Restore Network Settings. A message appears stating that the network defaults will be restored.

4. Touch Yes.

5. Print the network configuration page and verify that the network settings have been reset.

NOTE: When you reset the printer network settings, previously configured wireless and Ethernet settings (such as the link speed or IP address) are removed. The IP address is set back to the Automatic mode.

For further details, please follow the user guide for this printer.

Please respond to this post with the result of your troubleshooting. I look forward to hearing from you.

Thanks for taking the time to try, but the whole point was that I couldn't perform the reset routine you suggested at the control panel because I was blocked from doing so by the printer Admin settings (although I don't know how, but I accept that it must be something I did when first setting up the printer).

I did get help from HP support... did a partial reset using an unpublished method via the printer control panel.

Thanks again...

I am not able to connect to my printer after an Win update on 25th of May. The printer menu only shows gray printing for settings and asks for the person who set up the device.

I did not choose any Admin rights during setup. All was open before the win update from yesterday. I m working in a private network an use a specified IP for the printer. The printer is connected to the network, but does not react. doctor program does not help.

After installing the basis Software again, I have only more not working printers.

I need to access the printer menue to ..... change the IP adress or....

Taking off power and restarting router, internet, printer doesn´t chnage anything. Info is Gateway failure

I had the same issue, locked control panel by some mystery admin person as I'm the only one who runs this printer, the 7740. Had a new modem and router installed today as our other one by Uverse would constantly go out at random times. I tried your instructions to the letter with no success. This thing is going in the junk pile as it is out of warranty. I even called HP who, for $19.95 would try to help me but offered no positive results and instead immediately started a sales pitch for several other printers. I have always used HP but this one has caused constant problems to correct whenever the wifi would take a break.

But I did feel HOPE for a short time after reading your instructions. My plan always was to do a factory reset. BUT nowhere under HP Support online could I find anything about a locked control panel or a factory reset. Good way to get an unhappy consumer to go buy a new printer which is exactly what I am going to do!!

Thanks anyway Jeet!
