What happens, when you try to power off the printer ?
Did you try to press the copy button once more and what is the last thing you can see on the printer screen ?
Do you have installed the printhead and cartridges ?
Did you try to disconnect the power cord for 10 mins. to hard reset the printer ?
Sorry for the late reply, I got offline for day after waiting for your reply. Please let me know, what is happening at present.
