HP Printer Error E16

How to Resolve HP Printer Error E16 / 16 (No Network Connection)?

Seeing HP printer error E16 or 16 (No Network Connection) can be frustrating—especially when you’re in the middle of something important. This error usually means your printer has lost communication with the network it depends on to function. The good news? In most cases, it’s easy to fix without calling a technician.

Let’s break it down step by step and get your printer back online.

What Does HP Printer Error E16 / 16 Mean?

Error E16 or 16 typically appears on HP wireless printers when the device cannot connect to a Wi-Fi network. This can happen due to:

  • Weak or unstable internet connection
  • Incorrect Wi-Fi credentials
  • Router issues
  • Network settings reset on the printer
  • Firmware or driver problems

When the printer can’t detect a valid network, it stops responding and displays this error.

Common Reasons Behind the E16 / 16 Error

Before fixing the issue, it helps to know what might have caused it:

  • Wi-Fi network changed (new router or password)
  • Printer moved too far from the router
  • Temporary network outage
  • Router overload or misconfiguration
  • Outdated printer firmware
  • Corrupt printer network settings

How to Fix HP Printer Error E16 / 16

Try the solutions below in order. Most users find success within the first few steps.

1. Check Your Internet Connection

Start with the basics:

  • Make sure your Wi-Fi is working on other devices (phone or laptop).
  • Restart your router and modem.
  • Ensure the printer is within range of the Wi-Fi signal.

A weak signal alone can trigger the E16 error.

2. Restart the Printer

Sometimes the fix really is that simple:

  1. Turn off the printer.
  2. Unplug it from the power source.
  3. Wait about 60 seconds.
  4. Plug it back in and turn it on.

This refreshes the printer’s internal network settings.

3. Reconnect the Printer to Wi-Fi

If the printer lost its saved network details, reconnect it manually:

  • Open the printer’s control panel.
  • Go to Wireless Settings or Network Setup.
  • Select your Wi-Fi network.
  • Enter the correct password.

Make sure you’re connecting to the same network as your computer or mobile device.

4. Reset Network Settings on the Printer

If reconnecting doesn’t work:

  • Locate Restore Network Defaults in printer settings.
  • Confirm the reset.
  • Set up the Wi-Fi connection again from scratch.

This clears corrupted or outdated network data.

5. Update HP Printer Drivers and Firmware

Outdated software can block proper communication:

  • Visit HP’s official support page.
  • Download the latest printer driver for your model.
  • Install any available firmware updates.

Keeping everything updated prevents recurring network errors.

6. Check Firewall or Security Settings

Sometimes, security software blocks printer communication:

  • Temporarily disable firewall or antivirus software.
  • Try printing again.
  • If it works, add the printer as a trusted device.

Re-enable security software afterward.

7. Use HP Print and Scan Doctor

HP provides a free diagnostic tool:

  • Download HP Print and Scan Doctor.
  • Run the tool and follow on-screen instructions.
  • It automatically detects and fixes network problems.

This is especially helpful if you’re not tech-savvy.

When to Seek Additional Help

If error E16 / 16 still appears after trying all solutions:

  • Your router may not support the printer’s network requirements.
  • The printer’s wireless module could be faulty.
