Patent ID: 8807688

Claim:
A recording system comprising an image recording apparatus and an additional output stacker attached, wherein: the image recording apparatus comprises: an apparatus-side transport unit configured to transport a recording medium, an image recording unit configured to record an image on the recording medium according to image data, an apparatus-side output tray configured to receive the recording medium, a transport destination switching unit configured to switch selectively a transport destination of the recording medium between the apparatus-side output tray and the additional output stacker, such that the recording medium, on which the image has been recorded by the image recording unit, is directed either to the apparatus-side output tray or to the additional output stacker, and an apparatus-side controller configured to control the apparatus-side transport unit, the image recording unit, and the transport destination switching unit; and the additional output stacker is configured to attach to the image recording apparatus and comprises: an additional output tray configured to receive the recording medium, a stacker-side transport unit configured to transport the recording medium to the additional output tray, when the recording medium is directed to the additional output stacker by the transport destination switching unit, a jam detecting unit configured to detect a recording medium jam generated in the stacker-side transport unit, and a stacker-side controller configured to control the transport destination switching unit of the image recording apparatus, so that, when the jam detecting unit detects the recording medium jam, the transport destination switching unit switches the transport destination of the recording medium from the additional output stacker to the apparatus-side output tray.
