[C] In this model, the separation roller [A] is normally away from the feed roller [B]. When the paper feed station is selected, the separation roller solenoid [C] contacts the separation roller to the feed roller as explained in the previous two pages. This contact/release mechanism has the following three advantages: 1. When the paper feed motor turns on, all separation rollers in each feed stations rotate. If the separation roller is away from the feed roller, it reduces the mechanical load to the paper feed motor and drive mechanism, and also reduces wear of the rubber surface of the separation roller due to the friction between the separation roller and the feed roller. 2. After paper feeding is completed, paper sometimes remains in the gap between the feed roller and the separation roller. If the feed tray is drawn out in this condition, it is possible for the remaining paper to be torn. When the separation roller is away from the feed roller, remaining paper is released from the gap between the feed and the separation rollers. 3. When paper misfeeds occur around this area, the customer can easily pull out the jammed paper between the feed and the separation rollers because the separation roller is away from the feed roller.
