In a postage meter including a print module for printing on mail items, a feed tray for feeding in mail items to said print module, and a collection tray for receiving the mail items once they have been franked by the print module, said feed tray is inclined in two directions so that the mail items disposed on said tray are brought by gravity against a retractable jogging flap into the same determined position at which said print module affixes a postal imprint.
