Abstract: A printing system includes a printing unit, a position determiner that randomly determines a position where a first information code is to be set, a modifier that modifies print data for printing an image, the first information code, and a positional information code having recorded therein positional information at the time of printing that indicates the position determined by the position determiner so that the first information code is set at the position determined by the position determiner, an acquirer that acquires the position of the first information code on a print medium as positional information and acquires the positional information at the time of the printing from the positional information code, and a determiner that determines whether the printing result is a falsified matter based on comparison of the positional information after the printing with the positional information at the time of the printing.

Abstract: A post-processing device includes an intermediate tray on which a medium transported in a transport direction is placed, a discharge port through which the medium post-processed on the intermediate tray is discharged, a discharge tray which is disposed in a gravity direction with respect to the discharge port and on which the medium discharged from the discharge port is placed, and an elevating mechanism which elevates the discharge tray, in which the elevating mechanism can move the discharge tray to a first normal position and a first standby position positioned in a direction opposite to the gravity direction with respect to the first normal position, and moves the discharge tray to the first normal position or the first standby position according to an amount of ink before the medium comes in contact with the discharge tray or the medium previously placed on the discharge tray.

Abstract: An end unit includes: a processing tray including an upper surface on which a medium subjected to recording by a recording unit is mounted; a first paddle and a second paddle that transport, in direction +A, the medium mounted on the upper surface; an alignment section that aligns an edge portion of the medium, which was transported in direction +A by the first paddle and the second paddle, in direction +A; a post-processing section that performs post-processing for the medium aligned by the alignment section; and a load member that applies a load when the medium on the processing tray moves in direction −A opposite to direction +A.

Abstract: A post-processing device includes a transport path along which a medium printed with liquid ejected by a liquid ejecting portion is transported, an intermediate tray on which the medium is stacked, a first transporting member starting a first transporting operation of transporting the medium upstream in a transport direction after a rear end of the medium passes through the transport path, a rear-end alignment portion that comes into contact with the rear end of the medium transported by the first transporting member and that aligns the medium, a control portion controlling an operation of the first transporting member, and a detection portion detecting a transporting state of the medium in the intermediate tray, in which when the control portion determines, from an output of the detection portion, that the medium reaches the rear-end alignment portion, the control portion regulates the first transporting operation of the first transporting member.
