Factory Reset C4750 printer

[ChrisB5]

My printer was working on our previous network.  We have a new router and now I can't connect wirelessly.  I spent way too many hours trying to resolve this and have seen several times where a secret reset is sent through messenger.  Could I please get that sent to me?

Greetings @ChrisB5,

Welcome to HP Forums and Thanks for the post. 

I understand that you need assistance in configuring the printer on a new router, is that right?

Kudos to you for trying to troubleshoot the issue on your own.

Not to worry, I will be glad to assist you. 

Are you able to make a copy on the printer?

Do you have a USB cable to connect the printer and the computer?

Please select the wireless menu option on the front panel of the printer. 

Scroll to find an option to restore network defaults. 

Once the old network settings are removed from the printer, you would need to remove it from your computer as well.

Follow the procedure mentioned below to uninstall the printer software and settings cleanly and install it back. 

• Uninstall the printer from "programs and features" which can be accessed by doing a right-click on the Windows button (Please have the printer Off and disconnected during uninstallation.)
• Check in device manager, if the printer is listed there, please delete it. (Right-click on the Windows button to access device manager)
• Go to devices and printers, select any printer listed there and you will get some options on the top. 
• Click on print server properties. 
• You will get a popup, click on the drivers tab and delete all the HP printer drivers listed there, if any.
• Delete all the instances of your printer listed in devices and printers.
• Restart the PC.
• Once the PC is on the desktop, press Win + R, it would bring a Run dialog box, 
• Type %temp% in the run box and click Ok or hit the Enter button.
• It would bring up the temporary files folder. Delete the files in the folder (You might not be able to delete all the files, ignore them).
• If possible, delete the printer from the registries using Regedit or using any other 3rd party application.
• Restart the PC again. 
• Download the latest full feature driver from www.hp.com/drivers and install it on the computer.
• Power On/Connect the printer to your computer only when the setup prompts for the printer. 

Let me know if this helped.
