Abstract
A method for the calibration or recalibration of a conversion factor (web encoder resolution), used to determine the distance covered by a print substrate in a printing machine, in particular an electrophotographically operating printing machine, by the cycles of a rotary input type of encoder (web encoder) which sends a signal to the driver of the conveyor belt, preferably the rotation of a rotating drive component for the conveyor belt. This task is solved in that the number of phase pulse signals of the rotary input type of encoder which accumulates during the movement over the dimensions of the longitudinal extension known or otherwise measured section of the conveyer belt, is determined and compared to the known dimensions of the longitudinal extension.
