Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Lets try this first. Open the Printer like you were going to replace the ink catridges..Can you get to them to emove the ink cartridges.. If so, remove them.
Then, unplug the power cord from the back of the machine.
Then, unplug it from the wall. Then, press and hold the power button for 30 seconds.
Then, plug the printer back in, connect the power cord to the back of the printer, and then try to turn it on again.
What happens, do any lights come on? Does it make any noise?
Thank you for your response,
