Panasonic scanner KV-S3065CW

I just got my hands on one of these with a low meter that was working great but now when i power up it goes yellow light briefly and then Solid red light on panel-- Nothing moves-- I checked the right rear sensor in rear and its looks good--

when i hook it up to my PC/ panasonic utilty it says "Scanner door is open" ( of course is closed...) Also get a error U20 0000 on utility screen


Thanks in advance for your thoughts!!
