Post-processing apparatus

A post-processing apparatus comprising:

• a discharge section configured to discharge a medium having thereon information recorded by a recording section, the recording section recording the information by discharging liquid;
• a processing tray configured to be loaded with the medium discharged by the discharge section;
• an edge alignment section disposed on the processing tray and configured to align an edge of the medium;
• a transport section having contact with an upper surface of the medium mounted on the processing tray and configured to transport the medium to the edge alignment section;
• a position change section configured to change a relative position of the transport section with respect to the processing tray;
• a controller configured to change pressure of when the transport section makes contact with the medium by controlling the position change section;
• and
• a post-processing section configured to perform post-processing on the medium on the processing tray, wherein
• the controller changes the pressure based on processing information regarding processing to be performed on the medium,
• the processing information includes a transport time period from when the recording section records the information on the medium to when the discharge section discharges the medium, and
• when the transport time is shorter than a transport threshold value, the controller sets the pressure to a first pressure, whereas
• when the transport time is equal to or longer than the transport threshold value, the controller sets the pressure to a second pressure, where
• the first pressure is lower than the second pressure.

• a post-processing section configured to perform post-processing on the medium on the processing tray, wherein
• the controller changes the pressure based on processing information regarding processing to be performed on the medium,
• the processing information includes a total value of a first recording concentration of an upper surface of a first medium mounted on the processing tray and a second recording concentration of a lower surface of a second medium discharged on the processing tray by the discharge section subsequently to the first medium, and
• when the total value is equal to or higher than a total threshold value, the controller lowers the pressure than the pressure of when the total value is lower than the total threshold value.
