A method of printing a job in either a first mode or a second mode, to produce a set of prints from a set of print-related information transmitted to a print file, is provided. In the first mode, which occurs when the set of print-related information is less than a preselected quantity, a portion of the print file is filled with the set of print-related information and the set of print-related information is read with a marker for producing the set of prints. In the second mode, which occurs when the set of print-related information is greater than the preselected quantity, the steps of filling a portion of the print file with a subset of the set of print-related information and reading the subset with the marker are repeated until the set of print-related information is read completely.

A buckle adjust procedure that automatically adjusts the amount of buckle introduced into copy sheets. The buckle adjust procedure includes the measurement of the time period for the trail edge of a first set of buckled copy sheets at the registration station to pass under a pre-registration switch. A second measurement is made of a time period for the trail edge of a second set of unbuckled copy sheets to pass under the pre-registration switch. The two time periods are compared and if the difference exceeds an acceptable range, an automatic adjustment is made to the amount of buckle introduced into copy sheets. The amount of buckle is determined by the time period that the copy sheets are driven into braked registration rolls.

The present invention is concerned with the automatic adjustment of the optical components in an optical scanning system after the tech rep has visually inspected sample copies with a test pattern and entered adjustment numbers at the control console. The control determines the optimum relative position of the optical components for a focus and various magnification ratios and stores these relationships as reference numbers in memory for reference at the selected magnification ratios. These reference numbers can be altered as future copies are inspected by the tech rep and appropriate evaluation numbers are entered into the control. In a specific embodiment, one sample copy is compared by the tech rep with the test pattern to adjust the magnification setting and a sequence of five set copies are produced to coarse adjust and fine adjust focus.
