Does anyone have an Intec Colorcut FB8000? We just got one second hand. The tray in the auto sheet feeder won't move up to the ready position. It's just stuck in the down position. I'm pretty sure it's not the motor, because when I turn it manually and then press the "lower stack " button, the motor kicks on and lowers the tray. Has anyone else had this problem or can you point me in the right direction for reliable resources?
