I have a Xerox Phaser 7300. The A3 tray (Lower Tray Deck) is no longer recognised (ie in Printer setup, you cant actually choose it) and I've realized that the pin or plug that joins the Lower A3 tray to the Upper A4 tray was damaged during our office move. Does any body have a spare part for this or know where I can get one from? Doing a google search tells me the part number could be 116-1040-00??
