App not finding printer HP envy 6400

[Noldey]

Hi I’ve followed ALL the steps to connect my printer. So my Bluetooth is on, location services on etc … my printer previously worked then stopped working all of a sudden so followed the steps to remove printer and now it won’t pick it up. I have a purple light, e9 error code and a flashing wifi light. If anyone could help that would be grand! Thank you in advance

Welcome to the HP support community.

I understand that you are getting an E9 error on the printer, I am glad to assist you.

• Make sure the printer is on.
• Lift the ink cartridge access door until it locks into place.
• 
• At the back of the printer, press and hold the Power and Wireless buttons for 5 seconds.
• 
• Wait 2-3 minutes for the printer to restart, and then check the control panel for the E9 error.
• If the error no longer displays, you resolved the issue. The printer is ready for use.
• If the error still displays, continue with these steps.
• Close the cartridge access door.
• 
• On your computer or mobile device, close the HP Smart app, and then reopen it.
• Remove the printer from the HP Smart app. On the app home screen, right-click or long-press the printer name, and then select Hide Printer.
• 
• On the confirmation prompt, click Hide Printer again.
• Click Add Printer or the plus sign .
• A list of available printers display.
• Select the name of your printer, and then follow the instructions to set up the printer on a Wi-Fi network.
• When prompted, press the blinking Information button on the control panel, and then follow the remaining instructions.
• If you cannot complete the setup, close the HP Smart app, and then remove and re-add the printer again.
• When the app home screen displays, restart the printer to complete the setup.
• The control panel no longer displays the E9 error, and the printer is ready to use.
