1.3 Paper Transportation System (1) Outline This printer employs automatic paper feeding from the media cassette. When toner images are formed on the transfer drum through the operations of the print system and transfer system, paper is fed by the pick-up roller and transported to the register roller. The transported paper is further transported to the transfer, fuser and exit parts by the register roller synchronizing with the rotation of the transfer drum. (2) Structure of Paper Transportation System (Refer to Fig.4-25.) The paper transportation system consists of the following parts;
Media Cassette: Case to accommodate paper to be fed automatically.  Paper Pick-up Roller: Roller to feed sheets of paper one by one, preventing multi-feed.  Register Roller: Roller to transport papers synchronized with the transfer drum.  Transfer System: Print processing part consisting of transfer drum and transfer roller to transfer the toner image onto the paper.  Paper Discharger Unit: Corona generator to generate AC corona for separating paper from the transfer drum.  Fusing Unit: Mechanical part to fuse the toner image with heat rollers and fix it on the paper.  Paper Exit Unit: Mechanical part to exit the fused paper from the printer.  Paper Exit Roller: Roller to feed paper from the printer. IV-23
