A motor control system is provided. When it is determined that the attribute of the sheet of the printing target job is different from the attribute of the sheet in the sheet storage unit, it is determined whether the attribute of the sheet of another job also designates the sheet storage unit. The resulting curvature of the tool tip substantially corresponds to the medial curve of a femoral component of a hip replacement system. The chamber has a chamber size, the chamber size being characterized by an actual spatial dimension normal to the imaging path. When the basis weight of the transfer material is larger than a first threshold value, the airflow control part sets the amount of air to be blown to a value smaller than that in a case where the basis weight of the transfer material is smaller than the first threshold value. The magnetoresistive qualities of a head design incorporating the SDT junction are not directly related to head resistance, head geometry, bias current and film thickness.
