Abstract

Provided are an auto document feeder (ADF), a scanner including the ADF, and a method of controlling auto document feeding. The ADF includes: a feed unit picking up a sheet of paper and carrying the sheet of paper to a scan unit; a feed control unit controlling the feed unit; and a retry control unit. If a sheet of paper is not normally picked up by the feed unit, the retry control unit decreases a speed of a motor driving the feed unit or increases a current supplied to the motor for picking up the sheet of paper. Therefore, although sheets of paper are not normally fed when a user intends to use various kinds of sheets of paper with the ADF, the retry control unit may stabilize feeding of the feeding of the sheets of paper. Thus, efficient, convenient, and high-quality paper feeding may be possible.
