Abstract
The present invention relates to a paper-feed control apparatus for a printer that reduces the frequency of paper-feed failures by automatically performing a clearing operation if a malfunction should occur in the supply of paper. Paper stacked in a paper tray 1 is separated one sheet at a time by separator tabs 5, and then is sent in a conveyor direction by the rotation of a feed roller 3. If the paper should jam partway during this separation and conveyor process, a paper-feed motor that drives the feed roller 3 is driven intermittently. This intermittent operation produces a large paper conveyor force from repeated generation of a large frictional force between the roller and the paper, and thus the frequency of paper-feed failures is reduced.
