A media transport module comprising: a transport extending from a pick coupling area to a stacking port; and a retractable guide. The retractable guide is moveable to extend beyond the stacking port when media items are being stacked and thereby guide media items ejected from the stacking port onto a carriage plate. The retractable guide is also moveable to retract to the stacking port when media items have been stacked so that the carriage plate can close without touching the retractable guide.
