I just got a Laserjet 1300, took it out of the box, installed the toner and turned it on. There is paper in the tray. On the left, both the amber and green lights are lit solid. When you press the button, the amber light goes out and stays out for the duration of the button press (if you hold the button down), then comes back on when you let up on the button. It seems to me this is a paper sensor issue, is this correct? Any help would be appreciated!
