Separation Roller Method
The printer has a separation roller method to prevent multiple sheets of media from entering
to the printer.
The paper separation roller follows the rotational direction of the pick-up roller because it
does not have its own driving force.
- Normal-feed
The separation roller is driven by the pickup roller through a sheet of print media. That is,
the separation roller rotates in the media feed direction.
- Multiple-feed
The low friction force between the sheets weakens the rotational force from the pickup
roller. The separation roller is limited its rotational force and it does not rotate with such
weak driving force from the pickup roller. As the separation roller does not rotate, the
multiple sheets are not fed to the printer.
