Example media size sensor assemblies and media handling device including the example media size sensor assemblies are disclosed. In an example, the media size sensor assembly includes a sensor to be mounted within the media handling device, the sensor to detect reflected light. In addition, the media size sensor assembly includes a plurality of reflective surfaces to be coupled to a width adjustment wall of a storage tray of the media handling device, such that movement of the width adjustment wall is to align a selected one of the plurality of reflective surfaces with the sensor. The reflective surfaces of the plurality of reflective surfaces are to reflect different amounts of light.

A document transport device includes a placement portion, a slide member, a movable piece, and a detector. A document is to be placed on the placement portion. The slide member includes a document guide that contacts one lateral side of the document which is placed on the placement portion. The movable piece is provided to the slide member, and includes a shading pattern composed of plural patches that have plural densities corresponding to plural document sizes and having plural adjacent patch density differences that are different from each other. The detector detects a density of the shading pattern, and outputs an output signal for document size recognition.

A controller drives a floating unit and a conveyor to perform a sheet feed operation, during the sheet feed operation, acquires an amount of received light at a detector during floating of sheets floated by the floating unit each time each sheet is conveyed by the conveyor, and perform a following control of lifting a stacking tray upon the acquired amount of received light being less than a threshold value. The controller, after start of the sheet feed operation, samples amounts of received light at the detector during floating of the sheets floated by the floating unit, performs a threshold value determination process of determining the threshold value by using the sampled amounts of received light, and starts the following control upon determining the threshold value.

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.
