I'm sorry about the issue. Was it working previously? Or is this a new printer or new computer or new Internet modem/router, etc.?
Is the printer connected to the computer with a USB cable? Or is the connection wireless?
Do you have windows xp, vista, or 7, or 8, 10, or mac computer?
What happens when you install the printer's driver / software? Is there any error or message?
Please reply at the box below. Thank you,
