The present apparatus is directed to a supporting structure wherein a matrix printhead is moved along a pair of transport rails. In order to minimize print line distortion as the carrier moves along these two rails, it is critical that the inherent distortion in each of the rails be controlled. This is accomplished by a preexamination of each of the two rails to determine direction in which the rail is distorted or bowed. Then, each of the rails is marked with an indicia to indicate the point of direction of the bowing. When the rails are inserted into the frame, each rail is inserted so that the bowing or distortion in each of the rails will correspond in position to the bowing and distortion of the other rail.
