I'm sorry about the issue. Is only the Error light showing red? Please see at the website below:
Do you have windows xp, vista, or 7, or 8, 10, or mac computer?
Are you currently able to print or not?
Is the printer connected to the computer with a USB cable? Or is it wireless?
If you turn off the printer, then disconnect the power cord from the printer for about 5 minutes, then re-connect, then turn on, then wait a bit, then can you print?
Please reply at the box below. Thank you.
