Page 279 2KR/2KS (2) Laser scanner section The image data scanned by the CCD PWB (CCDPWB) is processed on the main PWB (MPWB) and transmitted from engine PWB (EPWB) as image printing data to the laser scanner unit (LSU). By repeatedly turning the laser on and off, the laser scanner unit forms a latent image on the drum surface.

Page 281 2KR/2KS 2-1-3 Drum section The drum section consists of the drum, main charger unit and cleaning section. The drum is electrically charged uniformly by means of a main charger unit to form a latent image on the surface. In addi- tion, the main charger unit is equipped with the main charger cleaning motor, and it is cleaning automatically.

Page 283 2KR/2KS-2 2-1-4 Developing section The developing section consists of the developing unit and the toner container. The developing unit consists of the developing sleeve where a magnetic toner blade is formed, the doctor blade and the developing spirals that agitate the toner. When the toner sensor (TNS) detects a low toner level in the developing unit, the toner replenishment signal is output to the engine PWB (EPWB).

Page 285 2KR/2KS (1) Single component developing system This machine uses the single component developing system, and reversal processing is performed with a + charged drum and a + charged magnetic toner. With the single component developing system, toner is electrically charged by friction with the developing sleeve and + charged when it passes through the magnetic toner blade.
Page 286 2KR/2KS 2-1-5 Transfer and separation sections The transfer and separation section consists mainly of the transfer roller, separation electrode and drum separation claws. A high voltage generated by the high-voltage PWB (HVPWB) is applied to the transfer roller for transfer charging. Paper after transfer is separated from the drum by applying separation bias that is output from the high-voltage PWB (HVPWB) to the separation electrode.
Page 287 2KR/2KS 2-1-6 Fuser section The fuser section consists of the parts shown in Figure. When paper reaches the fuser section after the transfer process, it passes between the press roller and heat roller, which is heated by fuser heaters 1 or 2 (FH1 or FH2). Pressure is applied by the fuser pressure springs so that the toner on the paper is melted, fused and fixed onto the paper.

Page 289 2KR/2KS 2-1-7 Eject and switchback sections The eject and switchback sections eject paper on which fixing has ended with the eject roller that is rotated by forward rotation of the eject motor. In duplex copying, paper is turned over by reverse rotation of the eject motor. When paper is transferred to the job separa- tor or the internal finisher, the feedshift solenoid (FSSOL) is turned on to activate the feedshift guide to switch the paper transfer path.

Page 291: Duplex Section
2KR/2KS 2-1-8 Duplex section The duplex section consists of the components shown in figure. In duplex mode, after copying on to the reverse face of the paper, the paper is reversed in the switchback section and conveyed to the duplex section. The paper is then conveyed to the paper feed section by the upper and lower duplex feed rollers.
