Shown and described is an improved sheet transport apparatus for use in a printer. A buckle develops in sheets fed around a drum past a print station because the pitch radius of the paper is larger than the pitch radius of the transport belts. The paper, which is held against the drum by pressure rollers, thus travels farther than the belts. This buckle of excess paper creates a problem because the paper must be held tightly against the drum at the print point for good print quality. A paper tensioning device has been used to compensate for the buckle. The present design eliminates all buckle and thereby eliminates the need for a tensioner.
