Page 207: Mp Tray Paper Feed Section
2K3/2L3 (2) MP tray paper feed section The MP tray can contain 100 sheets. Feeding from the MP tray is performed by the rotation of the MP paper feed roller. Also, function of the MP separation pad prevents paper from multiple feeding. Figure 2-1-3 MP tray paper feed section 1.
Page 208: Conveying Section
2K3/2L3 (3) Conveying section The conveying section conveys paper to the transfer/separation section as paper feeding from the cassette or MP tray, or as paper refeeding for duplex printing. Paper by feeding is conveyed by the paper feed roller to the position where the registration sensor (RS) is turned on, and then sent to the transfer/separation section by the right registration roller and left registration roller.
Page 209: Drum Section
2K3/2L3 2-1-2 Drum section The drum section consists of the drum, the charger roller unit, and the cleaning unit, and the drum surface is uniformly charged in preparation for formation of residual image by laser beam. After transfer is complete, toner remaining on the drum surface is chipped off with the cleaning blade and is collected to the waste toner box with the drum screw.

2K3/2L3 (2) Laser scanner section The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser beam is dispersed as the polygon motor (PM) revolves to reflect the laser beam over the drum. Various lenses and mirror are housed in the laser scanner unit, adjust the diameter of the laser beam, and focalize it at the drum surface.
Page 216: Transfer/Separation Section
2K3/2L3 2-1-5 Transfer/Separation section The transfer and separation section consists mainly of the transfer roller, separation electrode and drum sep- aration claws. A high voltage generated by the high voltage PWB (HVPWB) is applied to the transfer roller for transfer charg- ing.
Page 217: Fuser Section
2K3/2L3 2-1-6 Fuser section The paper sent from the transfer/separation section is interleaved between the heat roller and the press roller. The heat roller is heated by the fuser heater (FH), and the toner is fused by heat and pressure and fixed onto the paper because the press roller is pressed by the fuser press spring.
