The unit consists of:* OPC Drum * Waste Toner Ass'y used to collect waste toner remaining on the OPC drum, * Charge Roller Assy * Etc. 2) ITB Unit ITB stands for Image Transfer Belt. An image developed on the OPC Drum is transferred first to the ITB. This is called the T1 Transfer (Primary Image Transfer). Images are built up in layers on the ITB. First the Yellow (Y) colour image is created on the OPC and transferred to the ITB Next the Magenta (M) colour image is created on the OPC and transferred to the ITB Followed by the Cyan (C) and Black (K) images. 3) Transfer Roller Once the complete, full colour, image, has been built up on the ITB the Transfer Roller is used to transfer the image onto paper. This is called the T2 Transfer (Secondary Image Transfer) 4) FCT (First Cassette Tray) It stores and automatically feeds print paper. Pick-up Roller picks up paper, controls drive, feeds paper, removes static electricity, and so on. > Spec. * Paper arrange way : Side Registration * Paper Direction : FISO (Front-in, Side-Out) * Cassette Type : A4, Ltr * Paper Discharge : Separation Claw * Capacity : 250 Sheets (Standard paper 75mg/m? 20lb) * Paper Size : A4, Letter * Paper Weight (average) : 60~90g/m2 (16~24lbs) * Paper Type : General Printing Paper * Additional Function : Paper Empty Sensor 5) SCT (Second Cassette Tray) This additionally stores and automatically feeds printing paper.

Pick-up Roller Feed Sensor Paper Empty Sensor 2) Jam1 (Jam inside printer) * After the leading edge of the paper has reached the feed sensor, the feed sensor doesn't turn off (fails to detect the trailing edge of the paper) in a certain time * After the leading edge of the paper has passed the feed sensor, it doesn't reach the exit sensor in a certain time. * Exit senor is faulty and does not detect paper. Exit Sensor Feed Sensor 3) Jam2 (Jam in exit area) * After the leading edge of the paper has passed, the trailing edge of the paper has not passed the exit sensor within a certain time * The paper drive motor has been driving for longer than the time needed for the longest paper size and the exit sensor is not off. Exit Sensor 7-2 Traninung Manual Samsung Electronics Alignment & Adjustments 4) Jam duplex (Jam in duplex area) * Jam duplex occurs when printing the reverse side of the paper during duplex printing. After printing the front side the duplex solenoid must operate in order to feed the paper back into the duplex path. If the solenoid fails paper may be stuck in the exit roller and is not fully ejected into the exit tray. * If the duplex solenoid operates paper is fed back into the machine. If the leading edge of the paper does not reach the feed sensor in a certain time then Jam Duplex occurs. - This can be cause by paper being jammed in the duplex path area. Exit Sensor Feed Sensor 5) Jam MPF * Paper could not be picked up from the MPF tray. * After pickup, a paper has been fed, but it doesn't reach the feed sensor in a certain time. * Feed sensor is faulty and does not detect paper.

System Outline 5 5 System Outline This chapter describes the functions and operating principals of the main components. 5.1 CLP (Color Laser Printing) Process 5.1.1 OPC Drum Unit (Charge Section) The OPC Unit is the image formation unit and it consists of the OPC drum, waster toner assembly, charge roller assembly, etc. (see diagram below). OPC Drum Charge Roller Cleaning Blade Waste Toner Tank -1000V ~ -1500V Eraser Lamp LSU Charge Roller Cleaning Roller Charge Bias HVPS 1) Structure * OPC drum: The laser light coming from the LSU forms an latent electric image on the surface of the OPC drum. * Cleaning Blade: Removes remaining unwanted toner from the OPC drum. * Waste toner tank: Collects and stores the waste toner. * Charge roller: The charge roller is charged to a negative high voltage (-1KV~1.5KV) It is in contact with the OPC drum and produces a uniform (-) voltage on its surface of approximately -500~800V. 2) Type * * * * * * * * Life span: 50K Images (Color 12.5K) Waste toner removal: Transferred to a user replaceable tank Waste tank sensors: LED type, detects tank present and tank full OPC drum diameter: 120mm Power: Main motor (BLDC) Charging method: Charge roller Eraser method: LED lamp (+5V/2Pin) PTL: LED lamp (+5V/2Pin) Traninung Manual Samsung Electronics 5-1 System Outline 5.1.2 LSU (Exposure) The bitmap image data stream is used to switch the LSU data beam. Where white paper is required the beam is off, where ink is required the beam is turned on. When the laser is on and the beam strikes the OPC drum surface the charge is reduced to -50V, where the beam is switched off the charge on the OPC surface remains at -600V. In consequence a latent image is formed on the drum surface. -600V -600V -50V Polygon Motor (30,000rpm) Reflecting Mirror 5-2 Traninung Manual Samsung Electronics System Outline 5.1.3 Toner Cartridge (Development Section) In the development stage toner particles are transferred from the toner cartridge onto the surface of the OPC drum. The OPC drum and the developer roller rotate in opposite directions. Toner on the developer roller is charged to the developing voltage (see page 5-7). Toner is attracted to the OPC drum in those areas where the OPC drum surface charge is -50V. Toner is not attracted to those areas of the surface carrying a -600V charge. Dev Gap DEV. - Black DEV. - Yellow Dev Roller OPC Drum OPC DEV. - Magenta DEV. - Cyan Developing Voltage 1) Type * Developing method: Non-magnetic, Mono-component developing system. * Toner cartridge order: K, Y, M, C from top. * Developing sequence: Y, M, C, K * Life span: 7K(K) / 5K(C, M, Y) * Power: DEVE motor (BLDC) * Power transmission: Electric clutch * Toner remaining: TRC sensor (see page 5-7) + Dot counting method Traninung Manual Samsung Electronics 5-3 System Outline 2) Developing state of color The page image is built up from each of the 4 colors and transferred to the paper as described below. > Developing sequence: Y,
