JA: Sometimes things that you think will be really complicated end up being easy to fix. The Printer Technician I'm going to connect you with knows all the tricks and shortcuts. Is there anything else important you think the Printer Technician should know?

Hi, have you tried running through the setup wizard again for the printer? Often in instances like these you will need to set it to factory settings, run the setup wizard and making the selections for wifi etc.
