Even after trying basics like restarting the printer, deleting Wi-Fi, reconnecting, removing the printer from your account, or performing a factory reset, the error can still persist. In this guide, I’ll explain why this happens and walk you through step-by-step fixes that usually resolve it.

## What Does Error OW_4XX_OWSWS00001 Mean?
This error appears when your printer cannot complete cloud registration with HP servers. In simple terms, your printer and your HP account aren’t able to “handshake” properly over the internet.

It’s usually caused by one (or more) of the following:

Weak or unstable Wi-Fi connection

Router blocking printer communication

VPN, firewall, or antivirus interference

Incorrect network band (2.4 GHz vs 5 GHz)

Corrupt setup session in the HP Smart app

Outdated printer firmware

Account sync problems on HP’s side

When this happens, your printer may also fail to connect to Wi-Fi properly—even if the network name appears during setup.

## Before You Start (Quick Checklist)

Do these first—they solve many cases instantly:

Restart printer + router + phone/PC together

Place the printer close to the router

Make sure your phone/PC is on the same Wi-Fi network as the printer

Temporarily turn OFF VPN

Pause third-party antivirus/firewall during setup

Once that’s done, follow the fixes below in order.

## Fix 1: Power Reset Everything (Proper Way)

A simple restart isn’t always enough. Do a full power reset:

1. Turn OFF the printer and unplug it.
1. Turn OFF your Wi-Fi router.
1. Wait 60 seconds.
1. Turn ON the router and wait until internet is stable.
1. Plug in and power ON the printer.
1. Try registration again.

This clears cached network sessions that often trigger OW_4XX errors.

## Fix 2: Use 2.4 GHz Wi-Fi (Very Important)
Many HP printers struggle with 5 GHz networks during registration.

* If your router combines both bands under one name:
* Log in to your router settings
* Temporarily enable 2.4 GHz only (or create a separate SSID)
* Connect your phone/PC to 2.4 GHz
* Re-run printer setup

After registration succeeds, you can re-enable 5 GHz.

## Fix 3: Remove the Printer Completely and Re-Add It
Partial removals don’t always work. Do a clean removal:

1. Open the HP Smart app
1. Delete the printer from the app
1. On your device, remove the printer from Devices & Printers
1. Restart your phone/PC
1. Open HP Smart → Add Printer / Set Up New Printer

This forces a fresh registration session instead of reusing a broken one.

## Fix 4: Restore Network Settings on the Printer
Factory reset alone may not clear network data. Instead, reset network settings:

On most HP Smart Tank models:
Hold Black + Color buttons together for ~5 seconds until the blue light blinks.

After this:

Reconnect Wi-Fi from HP Smart

Try registering again

## Fix 5: Disable Firewall or Antivirus Temporarily
Security software can block the cloud ports needed for registration.

Temporarily disable:

Third-party antivirus

Windows Firewall (briefly, for testing)

Then retry setup. If it works, add HP Smart as an allowed app afterward.

## Fix 6: Update Printer Firmware
Outdated firmware can cause account registration failures.

Inside HP Smart:

**Go to Printer Settings → Advanced Settings / Tools → Firmware Update**
Install any available update, restart the printer, and retry registration.

## Fix 7: Try a Different Device or Hotspot (Powerful Test)

If nothing works:

Install HP Smart on another phone or computer

Or connect the printer to a mobile hotspot temporarily

If registration succeeds on hotspot, your home network/router is the real cause.

## When Nothing Works
If you’ve already tried:

Power cycling

Deleting Wi-Fi and reconnecting

Removing and re-adding the printer

Factory/network reset

Different networks or devices

**…and you still get OW_4XX_OWSWS00001, the issue may be related to:**

Account-side activation

Printer cloud registration lock

Deep network configuration problems

At this point, advanced troubleshooting is usually required.

## Final Thoughts

The “Unable to register printer to account” (OW_4XX_OWSWS00001) error is frustrating—but in most cases, it’s caused by Wi-Fi band conflicts, blocked network traffic, or a corrupted setup session.

Follow the steps above carefully, especially switching to 2.4 GHz, doing a true network reset, and re-adding the printer from scratch. These resolve the problem for most users.
