When the HP LaserJet MFP M234dwe printer displays an "ER61" error code, it's typically indicating a problem with connecting to a Wi-Fi network.
Here are detailed troubleshooting steps to resolve this issue:
Understand the Light Pattern:
When the printer's front light flashes purple, it signifies that the printer is in Wi-Fi setup mode but unable to connect to a network.
Check Wi-Fi Connectivity:
Ensure that the Wi-Fi network is functioning correctly and is compatible with the printer. Check that other devices can connect to the same Wi-Fi network without issues.
Reset Wireless Settings:
Reset the printer’s wireless settings by pressing and holding the wireless button and the cancel button together until the front light pulses purple. This action will set the printer into Wireless Setup Mode.
Reconnect to Wi-Fi:
Utilize the HP app software to reconnect your printer to the Wi-Fi network.
Open the HP app on your mobile device or computer.
Follow the on-screen instructions to add your printer.
Ensure your mobile device or computer is on the same network you wish the printer to connect to.
Update Printer Firmware:
Ensure that the printer firmware is up to date as older firmware can sometimes cause connectivity issues.
Check Network Frequency:
Make sure your network is not operating on a frequency higher than 2.4 GHz if your printer does not support higher frequencies.
Move the Printer:
Sometimes physical obstructions can block the Wi-Fi signal. Try moving the printer closer to the router to ensure a good signal.
Power Cycle the Printer:
Try turning off the printer, unplugging it from the power source, waiting a minute, and then plugging it back in and turning it back on.
Review Printer Settings:
Navigate to the printer’s settings using the HP app to ensure all settings are configured correctly.
