These retard rollers and sheet feed belts are abrasion-resistant and ensure stable document feeding.
As copy machines and printers are becoming faster in operation and higher in image quality, there is a growing demand for ADF retard rollers and sheet feed belts made of materials that offer high resistance to abrasion and enable a larger nip width. In addition, ADF retard rollers and sheet feed belts must not only keep fluctuations in the friction coefficient minimal but also reduce the noise caused by vibration from the friction between the retard roller and paper during document transport and minimize the transfer of pencil lead powder and other particles from the document. Moreover, they must handle a variety of paper types. Yamauchi supplies highly reliable retard rollers and sheet feed belts that are created based on an original material design to prevent these problems.
