Hi Shelagh. Welcome to justanswer.
Are you using Windows computer? If yes, then go to Control Panel. Then click Devices and Printers. Do you see your printer listed there?
Right click the printer, and click See What's Printing. A window will get opened
Then click Printer on that window and then un-check USE PRINTER OFFLINE
Is your printer's wifi led glowing?
Set the printer's network connection once again.
Can you choose Secure Remote Assistance so that I can check the matter myself
No. Do this first.
Select WIFI SETUP from the LCD homescreen, and then press ok.
Now scroll down the list and If you see Enable wifi then select it and press ok
Go to Wifi Setup Wizard
Do you see your Home network listed there? If yes then press ok and enter the password
Turn off the printer and then again check
Is your printer connected to the same network?
Remove the printer from your computer and then again install it
Once you click this link below(CLICK HERE)A file will automatically get downloaded. Check your download section, a file named ELSINORE.SCREENCONNECT will be present. Just open that file so that I can connect to your computer.
Is the problem resolved now?
That's great Shelagh. Have a wonderful evening.
