Pickup-and-feed operation (EF) The envelope in the envelope feeder is fed into the product individually. Pickup and feed sequence of operation (EF) 1. The envelope feeder driver drives the envelope pickup motor (M1800) when it receives a pickup command from the DC controller. Accordingly the envelope pickup roller, upper separation roller and lower separation roller rotate to pick up envelope. 2. The upper separation roller and lower separation roller remove any multiple-fed envelopes and one envelope is fed into the product.
