# Unable to Register Printer to Account – Error Code OW_4XX_OWSWS00001 (Complete Fix Guide) If you’re seeing “Unable to register the printer to the account” along with Error Code: OW_4XX_OWSWS00001, you’re not alone. This is a common setup and connectivity issue on many HP printers—especially during first-time registration or Wi-Fi reconfiguration. **Call for Help 1-888-765-0492** 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firewall, or antivirus interference Incorrect network band (2.4 GHz vs 5 GHz) Corrupt setup session in the HP Smart app Outdated printer firmware Account sync problems on HP’s side When this happens, your printer may also fail to connect to Wi-Fi properly—even if the network name appears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. ### Call for Expert Assistance: 1-888-765-0492 Get help with: Printer account registration errors Wi-Fi connection failures Firmware recovery HP Smart setup issues Network-level printer configuration ## 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.
