I'm sorry about the issue. What's the error or message?
Is the printer connected to the computer with a USB cable? Or is the connection wireless?
Are you still able to make a copy from the printer's glass (not print from the computer)?
What's your Mac OS X version, i.e., 10.6, 10.7, 10.8, 10.9, 10.10, etc.?
