Paper Drawers

Hi, I've got a Bizhub C652ds a great printer but I need to actually remove the paper drawers(s) from it in order to get to a piece of A3 paper that is jammed inside the printer and which can't be accessed from the various doors. There seems to be no levers to release the paper drawers and trying to lift out the drawers like in other KM models doesn't work either. Any assistance with a solution would be appreciated. Thanks Peter
