Abstract
A sheet transport apparatus includes a first belt having a first pattern of first vacuum holes, and a second belt having a second pattern of second vacuum holes. The first belt is positioned on and contacts the second belt. The first belt contacts sheets to be transported. When transporting the sheets on the first belt separated by spaces between the sheets, the first pulleys and second pulleys rotate together and the first belt and the second belt move together. When not transporting the sheets, a controller controls pulleys to move the first belt relative to the second belt so as to leave blocked-hole regions of the first belt where the spaces between the sheets are located. The blocked-hole regions are locations of the first belt where the first vacuum holes are unaligned with the second vacuum holes and the first vacuum holes are blocked by the second belt.
