ABSTRACT:
A method of reading selected ones of an array of data frames from a microfiche medium substantially without errors attributable to misalignment of the frames. The method, which utilizes a microfiche reader-printer in adjusting for misalignment of the frames, includes the steps of determining the average distance between the frames along a first selected axis (e.g., the X-axis) of the array, and using said average distance in positioning the frames along the axis for reading. The frames are separated from each other by a predetermined nominal distance along the axis. The average distance is determined by dividing the distance between the outermost frames along the axis (the distance between the outermost frames being expressed in terms of the number of stepper motor steps needed to traverse said distance) by one less than the number of frames along said axis to produce a quotient, and adding the quotient to the predetermined nominal distance. A similar calculation of average distance between frames along a second selected axis (e.g., the Y-axis) is performed prior to positioning selected frames along said second axis for reading.
