Q: Ever since i tried to print ontoOHP's my printer has taken a turn for the worse, but the 'go' and 'cancel' lights are blinking together, almost continuously, the Manual tells me that this could mean low toner, or add paper, so did both of these things and still nothing will print!!
A: good lord I have not seen one of these for a while. It sounds as if one of the many sensors has jammed or broken. You have done what the manual has said so it is time to get it fixed by an engineer
