Abstract
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.
