These symbols are described below: DANGER: High risk of serious bodily injury or death may result from insufficient attention to or incorrect compliance with warning messages using this symbol. WARNING:Serious bodily injury or death may result from insufficient attention to or incorrect compliance with warning messages using this symbol.
1. Installation Precautions WARNING • Do not use a power supply with a voltage other than that specified. Avoid multiple connections to one outlet: they may cause fire or electric shock. When using an extension cable, always check that it is adequate for the rated current. ............................................................................................ • Connect the ground wire to a suitable grounding point. Not grounding the copier may cause fire or electric shock.
2. Precautions for Maintenance WARNING • Always remove the power plug from the wall outlet before starting machine disassembly. .............. • Always follow the procedures for maintenance described in the service manual and other related brochures. .........................................................................................................................................
• Do not pull on the AC power cord or connector wires on high-voltage components when removing them; always hold the plug itself. ...................................................................................................... • Do not route the power cable where it may be stood on or trapped. If necessary, protect it with a cable cover or other appropriate item. ..............................................................................................

Insert Compact Flash in a notch hole of the machine (insert the surface of Compact Flash toward the machine rear). 3. Insert the power plug and turn the power switch on.
2DA/2DB 1-7-3 Adjustment-free variable resistors (VR) The variable resistors listed below are set at the factory prior to shipping and cannot be adjusted in the field. • High-voltage PCB: VR201, VR202, VR301 • Drum unit zener PCB: VR1 1-7-4 Remarks on PCBs replacement Confirm the version of the firmware and upgrade the version in up-to-date state when replacing PCBs.
2DA/2DB 2-1-1 Paper feed section The paper feed section conveys paper from the drawer (one drawer is standard for 16 ppm model/two drawers are standard for 20 ppm model) 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. Drawer can hold up to 300 sheets of paper. Paper is fed from the drawer by the rotation of the forwarding pulley and paper feed pulley.

2DA/2DB 2-1-2 Optical section The optical section consists of the scanner, mirror frames and the image scanning unit for scanning and the laser scanner unit for printing.
2DA/2DB (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. The speed of the mirror frames is half the speed of the scanner.
2DA/2DB (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. Drum Figure 2-1-5 Laser scanner unit 1 Laser diode: Generates the laser beam which forms a latent image on the drum.
2DA/2DB The dimensions of the laser beam are as shown in Figure 2-1-6. Less than 100 µm Less than 85 µm Figure 2-1-6 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. The static latent image of the letter “A”, for example, is formed on the drum surface as shown in Figure 2-1-7.
2DA/2DB 2-1-3 Drum section The drum section consists of the drum, main charger section, cleaning section and cleaning lamp. The main charger section consists of main charger wire, main charger grid and main charger shield, and the drum is charged by a high voltage applied to the main charger wire. In addition, this section is equipped with a manual main charger cleaner that is used for cleaning the main charger wire.

2DA/2DB 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. Also, the toner container sensor (TCS) checks whether or not toner remains in the toner container.
2DA/2DB (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; the developing result is affected by the position of the poles on the magnet roller and the position of the doctor blade.
2DA/2DB (2) 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. The toner that has passed through the magnetic doctor blade forms a uniform layer on the developing sleeve.
2DA/2DB 2-1-5 Transfer and separation sections The transfer and separation sections consists of the transfer roller, separation electrode and drum separation claws. A high voltage generated by the high-voltage PCB (HVTPCB) 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 PCB (HVTPCB) to the separation electrode.

2DA/2DB 2-1-6 Fixing section The fixing section consists of the parts shown in figure. 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 and S (FH-M/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.

2DA/2DB 2-1-7 Exit and switchback sections The exit and switchback sections exit paper on which fixing has ended with the exit roller that is rotated by forward rotation of the exit motor. In duplex copying, paper is turned over by reverse rotation of the exit motor.
2DA/2DB 2-1-8 Duplex section 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 unit. The paper is then conveyed to the MFP paper feed section by the upper and lower duplex feed rollers.
2DA/2DB (1) Paper conveying operation in duplex copying Paper of which copying onto the reverse side is complete is conveyed to the switchback section, the exit motor switches from forward rotation to reverse rotation to switch the exit roller to reverse rotation, and the paper conveying direction is reversed. Paper that has been switched back is conveyed to the duplex unit via the exit roller and the switchback roller.
