How to factory reset printer?

[LeviA]

Please help! I have an error code on my hp printer OfficeJet  4635 and I’m trying to figure out how to factory reset the printer. When I have tried the solution of unplugging the power cord from the back of the printer and then from the wall outlet in order to reset it that did not work. Error code 0X83C0000A.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, I appreciate your efforts to try and resolve the issue. 
Let's try these steps to resolve the issue: 

Hard Reset: 

• 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 (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till the warm-up period finishes and the printer is idle.

Update the printer firmware:

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates.
 

For more information, go to Updating or Upgrading Printer Firmware.

If the issue persists, let us try a full reset on the printer. The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 
 

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
