Overlapping paper feed Dell 1720 Printer


Where is the separator pad located in the Dell 1720? I know where it is in most HP's but not Dell or Samsung.
 
Still don't even know if there is a separator pad in a Dell 1720 printer. I can't find it. And I don't think there is any Samsung printer that resembles his Dell. It does resemble a Lexmark E350 though. Can somebody tell me where the separator pad is?
