Page 49: Machine Composition
2 Machine Composition 2.1 Document scanning section 2.1.1 Auto Document Feeder (ADF) Section ADF (Auto Document Feeder) is a device that feeds the document continuously one page by one to the scanning section automatically. It consists mainly of document tray, Tx cover, inner guide, and platen cover. When the device is categorized by its functions, it consists of separator section that picks up each page of documents, register section that detects the leading edge of the document and controls the timing so that the document does not skew, and scan section that scans the document.
Page 50 Document detection The sizes of the documents are detected by the following sensors; Detection Sensor Document presence Leading and trailing edge detection DS3 (Back side) DEXIT Scanning section for simplex document The document sensor (DS2) is placed at scanning position to detect the leading edge and trailing edge of the document.
Page 51 When the backside of the document is scanned, the document will be discharged. Scanner (Reversible) (Switching)
Page 52 2.1.2 Flat Bed Scanner (FBS) section The FBS (Flat Bed Scanner) section consists of document glass (pane) and optical reading section (CIS). The CIS (Contact Image Sensor) carried on CIS holder keeps the focal length by moving along the pane. CIS moves and thereby exposes the lamp light uniformly to the document.
Page 53: Recording Section
2.2 Recording section Recording paper feed path The recording paper is separated from the remaining paper by friction of the pickup roller. The paper is trans- ferred along the paper guide until it reaches the register roller. Then it is transferred to the exit tray by the register roller.
Page 54 Paper feed timing chart...
Page 55 Warming-up 1 When the power is turned on, or the side or front cover is closed, the machine controls the warming-up temperature of the fuser. 2 Devices start working in the following order: Fan, RX2 motor, Dup CL1, RX1 motor, REGCL, and 2bin motor.
Page 56 8 When a predetermined time passes after REGCL is turned on in step 5, PFCL turns on, and the pick up roller feeds a paper. 9 The paper reaches the PRS, and loops at the resist roller. 10 The REGCL turns on, and the resist roller feeds the paper. 11 LED print head exposes the drum, and an image is developed then transferred to the second paper.
Page 57: Image Prosessing Section
2.3 Image prosessing section The image processing is roughly divided into the following steps: 1. Charging This step charges the drum negatively using the scorotron charger working on corona discharge system. 2. Exposure This step creates an electrostatic latent image on the drum surface by lighting the LED head (print head) according to the image data.
Page 58 2.3.1 Developing unit The machine uses an one-component nonmagnetic toner (negative). The toner is charged by friction be- tween developing roller and toner supply roller, and between developing roller and blade, and adheres to the developing roller. Part name Part name Blade OPC drum Developing roller...
Page 59 2.3.3 Charging mechanism The drum is charged evenly through a grid mesh by corona discharging of a multi-stylus electrode. The stylus type charger concentrates discharging to the grid mesh side, which generates less ozone than wire- electrical discharging. The generated ozone is removed by the ozone filter while emission. Part name Part name Charger case...
Page 60 2.3.4 Exposure mechanism The LED print head lights according to the image data transferred from the print controller, and exposes the drum surface. The exposed surface loses the energy of charge, and an invisible static image is created on the drum surface. Charge Non-exposed area Exposed area...
Page 61 2.3.5 Development mechanism The static image created in exposure step is developed through toner adherence. The toner is transferred using the potential difference between the drum potential and developing bias charged on transfer roller. The exposed area on the drum surface has higher potential (VL) than the developing bias (Vb) that makes the toner transfer from the developing roller to the drum surface.
Page 62 2.3.7 Separation mechanism The electrostatic force on the paper is removed by a separator stylus, and the paper separates from the drum. The drum separation scraper also helps the paper separate from the drum. Part name Part name Separation scraper Star roller Paper Separation stylus...

Page 64 2.3.10 Discharge mechanism After transfer step, erase light is exposed on the drum to neutralize remaining charge and to provide for the next charging. Part name Part name Eraser lamp OPC drum 2-16...
Page 65 2.3.11 Fusing mechanism The toner image transferred on to the paper is securely fixed. A heat roller system is used as the fusing system. The toner image is fused by heater roller heated by the heater lamp, and securely fixed by the pressure between the heater roller and press rollers. A thermistor detects and controls the heater roller temperature.
Page 66 Fusing temperature 1) Warming Up After the initialization of the printer, warming up of the printer starts and the Heater Lamp turns ON until the temperature of the Heater Roller reaches approx. 170 °C. 2) Printing When the printer obtains the printing command from its controller, the Heater Roller is main- tained at 180 °C.
