IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF

摘要

An image forming apparatus and a control method thereof are provided to separate a swing roller from a reverse roller to return the swing roller to the original position when a paper is inserted between a main roller and a sub discharge roller and insert the next paper between the main roller and a sub supply roller in order to control the paper discharge time and supply/discharge the papers at two sides of a center feed roller unit simultaneously. A badge unit(10) of an image forming apparatus comprises first and second feed rollers(11,13) and a reverse roller(12). The first feed roller is arranged at a fixing unit(8) to discharge a printed paper. The reverse roller switches a transfer direction of the paper fed from the first feed roller. The second feed roller discharges the paper fed from the reverse roller to the outside. A center feed roller unit(20) is placed between the first feed roller and the reverse roller. The center feed roller unit includes one main roller(21) having driving force, and sub discharge and supply rollers(22,23). A swing roller(24) which is arranged at the reverse roller guides the paper transferred from the first feed roller to the second feed roller. The swing roller is rotated by a lever(25) and is contacted with the reverse roller.
