摘要：
An apparatus comprises a vacuum belt having belt edges and a contact surface between the belt edges. The contact surface is adapted to contact sheets of print media and the sheets of print media have sheet edges and a central sheet region. The contact surface has a central belt region located where the central sheet region of the sheets of print media contacts the contact surface of the vacuum belt. The contact surface has border regions located where the sheet edges of the sheets of print media contact the contact surface of the vacuum belt. The central belt region is located between the border regions. The contact surface has vacuum holes, and the vacuum holes comprise an irregular pattern, such that a different density of holes is located within the border regions relative to the central belt region.
