(2) Format specification by format control tape (FCT)
The FCT is a looped paper tape with punched holes and sprocket holes for
feeding.
The punched hole data is read by the FCT unit and sent to the
printer to notify it of a forms feed format. Figure 4.11 is an example of
the FCT and shows the relationship between a forms feed format and punched
