Abstract
The two paper picking rollers of a dual paper picking device independently pull sheets of paper or other print medium from a supply and feed the same to an image printing device. With the two rollers pulling sheets of paper independently, the total amount of paper moved can be doubled without the need to increase the speed of either roller. Increasing the speed of a roller or other paper picking device increases the possibility that the paper will be mishandled and jam the image-printing device.
