4. The paper deck driver turns on the PD pickup solenoid (SL1700) when it receives a pickup command. Accordingly the PD pickup roller, PD feed roller and PD feed roller 1 rotate to pick up media in the paper deck. (PD pickup mechanism is the same way as that of the product). 5. The PD separation roller holds back any multiple-fed sheets and one sheet of media is fed in to the product. (PD multiple-feed prevention mechanism is the same way as that of the product). NOTE: The paper deck media size switch (SW1700) detects a media size in the paper deck.
