Abstract
A second print device prints images on a rear surface of a web with no sprockets after a first print device prints images on a front surface of the web. A CPF-OFF signal is generated at a time of when an irradiating unit of the second print device completes irradiating for a last page. The second print device calculates, based on a web transport speed at the generation timing of the CPF-OFF signal, a time duration required for the web to reach a predetermined waiting position after the CPF-OFF signal was generated, and starts counting a clock when the time duration elapses from when the CPF-OFF signal was generated. After a last-page image is completely transferred from a photosensitive drum onto the web, the web is transported in a reverse direction by a distance corresponding to the count value, thereby positioning the web at a predetermined waiting position.
