HP printers are known for their reliable wireless printing and scanning capabilities. However, after a router reset, many users experience issues where the HP printer scanner is not working properly. This usually happens because the network settings change during the router reset, disconnecting the printer from the WiFi network. As a result, the scanner may not communicate with your computer or mobile device.
What Causes HP Printer Scanner Not Working After Router Reset?
When you reset your router, the WiFi name (SSID), password, IP address, and network settings may change. Your HP printer was previously connected to the old network configuration, so it becomes disconnected after the reset. This leads to scanning errors, printer offline messages, or the HP Smart app not detecting the scanner.
Other common causes include:
- Printer not connected to the new WiFi network
- Outdated or missing HP printer drivers
- HP Smart login issues
- Firewall or antivirus blocking scanning
- Incorrect IP address configuration
- Disabled Web Services or scan services
Understanding the root cause helps in applying the correct troubleshooting steps.
