Abstract
An apparatus for conveying paper in a printer adapted to convey cut-sheet and fan-fold paper bi-directionally in a paper path. The apparatus includes a pair of paper conveying rollers positioned downstream of a print head and a pair of paper conveying rollers positioned upstream of the print head. At least one roller of one of the paper conveying roller pair has projections circumferentially extending away from the roller. The projections can be pressed against the roller to reduce the diameter and speed of the roller relative to its speed and diameter before compression to convey the paper in a first direction while preventing the formation of slack across the paper. In addition, the projections can be extended away from the roller to increase the diameter and speed of the roller relative to its speed and diameter before extension to convey the paper in a second direction while preventing the formation of slack across the paper.
