Page 275 2FD/2FF/2FG 2-1-1 Paper feed section The paper feed section consists of the primary feed and secondary feed subsections. Primary feed conveys paper from the upper drawer, lower drawer or bypass tray to the left and right registration rollers, at which point secondary feed takes place and the paper travels to the transfer section in sync with the printing timing.
Page 276 2FD/2FF/2FG The bypass table can be hold up to 200 sheets of paper at one time. Paper is fed from the bypass table by the rotation of the bypass forwarding pulley and bypass paper feed pulley. Also during paper feed, the bypass separation pulley prevents multiple sheets from being fed at one time by the torque limiter.

Page 279: Main Charging Section
2FD/2FF/2FG 2-1-2 Main charging section The main charging section consists of the main charger assembly, drum and so on. The drum is electrically charged uniformly (500 µA) by means of a grid to form a latent image on the surface. The main charger unit charges the drum so that a latent image is formed on the surface, the shield grid ensuring the charge is applied uniformly.

Page 281 2FD/2FF/2FG 2-1-3 Optical section The optical section consists of the scanner, mirror frame and image scanning unit for scanning and the laser scanner unit for printing. Figure 2-1-7 Optical section 1 Mirror 1 frame 2 Mirror 2 frame 3 Exposure lamp (EL) 4 Mirror 1 5 Mirror 2 6 Mirror 3...
Page 282 2FD/2FF/2FG (1) Original scanning The original image is illuminated by the exposure lamp (EL) and scanned by the CCD PCB (CCDPCB) in the image scanning unit via the three mirrors, the reflected light being converted to an electrical signal. The scanner and mirror frames travel to scan on the optical rails on the front and rear of the machine to scan from side to side.
Page 283 2FD/2FF/2FG (2) Image printing The image data scanned by the CCD PCB (CCDPCB) is processed on the main PCB (MPCB) and transmitted 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 284 2FD/2FF/2FG Drum Figure 2-1-10 Laser scanner unit (2) 1 Laser diode: Generates the laser beam which forms a latent image on the drum. 2 Collimator lens: Collimates the diffused laser beam emitted from the laser diode to convert it into a cylindrical beam. 3 Cylindrical lens: Shapes the collimated laser beam to suit the printing resolution.
Page 285 2FD/2FF/2FG The dimensions of the laser beam are as shown in Figure 2-1-11. Less than 100 µm Less than 85 µm Figure 2-1-11 Scanning in the main direction is provided by the rotating polygon mirror, while scanning in the auxiliary direction is provided by the rotating drum, forming a static latent image on the drum.
Page 286 2FD/2FF/2FG 2-1-4 Developing section The developing section consists of the developing unit and the toner container. The developing unit consists of the developing roller where a magnetic brush 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 main PCB (MPCB).
Page 287 2FD/2FF/2FG (1) Formation of magnetic brush The developing roller consists of a magnet roller with four poles and a sleeve roller. Rotation of the sleeve roller around the magnet roller entrains toner, which in turn forms a magnetic brush at pole N1 on the magnet roller. The height of the magnetic brush is regulated by the doctor blade;...
Page 288 2FD/2FF/2FG (2) Computing the absolute humidity The humidity sensor (HUMSENS) converts the relative humidity detected by the humidity sensing element into a voltage and sends it to the main PCB (MPCB). The main PCB (MPCB) computes the absolute humidity based on this HUMSENS signal and the temperature (ETTH signal) detected by the external temperature thermistor (ETTH).
Page 289 2FD/2FF/2FG (3) Single component developing system This machine uses the single component developing system, and reversal processing is performed with a + charged drum (a-Si) 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 doctor blade.
Page 290 2FD/2FF/2FG Developing bias parameters For the bias to the developing sleeve, an alternating current (AC) is applied. Parameters for the developing bias are shown below. Duty Vp-p: Difference between the maximum and the minimum of applied voltage 1.72 kV (fixed) Vf: Frequency Typically 2.6 kHz.
Page 291: Transfer And Separation Sections
2FD/2FF/2FG 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 transformer PCB (HVTPCB) is applied to the transfer roller for transfer charging (100 µA).

Also separation bias (SC REM) turns on.
Page 293: Cleaning And Charge Erasing Sections
2FD/2FF/2FG 2-1-6 Cleaning and charge erasing sections The cleaning section consists of the cleaning blade that removes residual toner from the drum surface after the transfer process, and the cleaning spiral that carries the residual toner back to the waste toner tank. The cleaning lamp (CL) consists of LEDs and removes residual charge on the drum before main charging.
Page 294 2FD/2FF/2FG 2-1-7 Fixing section The fixing section consists of the parts shown in Figure 2-1-24. When paper reaches the fixing section after the transfer process, it passes between the press roller and heat roller, which is heated by fixing heaters M or S (FH-M or FH-S). Pressure is applied by the fixing unit pressure springs so that the toner on the paper is melted, fused and fixed onto the paper.

Page 296: Eject And Switchback Sections
2FD/2FF/2FG 2-1-8 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 separator or the internal finisher, the feedshift solenoid (FSSOL) is turned on to activate the feedshift guide to switch the paper transfer path.

Page 298: Duplex Section
2FD/2FF/2FG 2-1-9 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 copier paper feed section by the upper and lower duplex feed rollers.
Page 299 2FD/2FF/2FG (1) Paper conveying operation in duplex copying Paper of which copying onto the reverse side is complete is conveyed to the switchback section, the eject motor switches from nomal rotation to reverse rotation to switch the eject roller to reverse rotation, and the paper conveying direction is reversed.
