Precautions In order to prevent accidents and to prevent damage to the equipment please read the precautions listed below carefully before servicing the printer and follow them closely. 1.1 Safety Warning (1) Only to be serviced by appropriately qualified service engineers. High voltages and lasers inside this product are dangerous. This printer should only be serviced by a suitably trained and qualified service engineer.
Precautions 1.2 Caution for safety 1.2.1 Toxic material This product contains toxic materials that could cause illness if ingested. (1) If the LCD control panel is damaged it is possible for the liquid inside to leak. This liquid is toxic. Contact with the skin should be avoided, wash any splashes from eyes or skin immediately and contact your doctor. If the liquid gets into the mouth or is swallowed see a doctor immediately. (2) Please keep toner cartridges away from children.
Precautions 1.2.3 Handling Precautions The following instructions are for your own personal safety, to avoid injury and so as not to damage the printer (1) Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause the printer to tip or fall. (2) The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your fingers, hair or clothing in any of these rotating devices.
Precautions 1.2.5 Disregarding this warning may cause bodily injury (1) Take care - some parts may be hot. The fuser unit works at a high temperature. Use caution when working on the printer. Wait for the fuser to cool down before disassembly. (2) Take care not to trap fingers or hair. Take care when using a printer. It contains many rotating parts. Ensure that fingers, hair, clothing etc. do not become caught in the mechanism as this could cause injury. (3) When you move the printer.
Precautions 1.3 ESD Precautions Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

Summary of Product 4.1.7 HVPS (High Voltage Power Supply) PBA The HVPS PBA uses the 24V created by the SMPS to generate the high voltages used by the charger, supply, T1,T2 and DEVE processes. For bests quality images these high voltages must be , controlled accurately to maintain the print quality. The high voltages produced are supplied to toner, OPC cartridge, ITB unit, and transfer roller.
Summary of product 1) Charging Voltage: Charger * Function : This high voltage is used to charge the surface of the OPC to about -500volt~800volt. * Output voltage : -200V~-2.0KV DC +/- 3% (Duty is changeable, no loading) * Error type :If MHV was not present, the surface of the OPC is not charged. As a result, toner on the developer roller is transferred over to the OPC drum: therefore, black paper could be printed out.

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).
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.
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 (-370V ± 3%). 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.
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, M, C, and K 1) A latent image containing only yellow toner is created on the OPC drum and then transferred onto the ITB. 2) A latent image containing only magenta toner is created on the OPC drum and then transferred onto the ITB to add to the yellow image already in the ITB.
System Outline 5.1.4 Image Transfer Section The toner image formed on the OPC drum is transferred to the ITB (Image Transfer Belt), this is called the primary image transfer. When the final image has been built on the ITB it is transferred onto paper, this is called the secondary image transfer. 1) Structure 1 2 3 4 ITB Home Sensor 5 OPC DRUM DUPLEX Paper Path NO. Name Description 1. Image Transfer Belt Used to build up the 4 color image from the OPC drum.
System Outline 2) Primary Image Transfer A colored page is split into 4 component color parts and developed one color at a time in turn on the OPC (in the order Y, M, C, K). The final image is built up on the ITB by transferring these separate color images from the OPC drum. Image Transfer Belt Image Transfer Roller OPC DRUM DUPLEX HVPS Primary Image Transfer Bias 3) PTL (Pre-Transfer Lamp) It is arrayed LED on PCB Board.
System Outline 4) Secondary Image Transfer The image is built up on the ITB (primary image transfer). This image is then transferred onto paper using the T2 transfer roller (roller transfer system) this process is known as the secondary image transfer. * The HVPS applies the Image Transfer Bias voltage to the Image Transfer Roller (T2), this transfers the image from the belt onto the paper.
System Outline 5.1.5 Fuser (Fusing Section) Toner that has been through the primary and secondary image transfer processes is fixed, semi-permanently, to the paper. The fuser unit consists of heat lamps (2 ea), heat rollers (2 ea), thermistor, and thermostats (2 ea). It melts the toner onto the paper using pressure and high temperature to complete the printing process.
System Outline 5.1.6 Exit After passing through the fuser paper is ejected into the paper exit tray. Any static electrical charge is removed by static discharge brushes. When operating in duplex print mode, after printing the front side of the page, the paper exit roller reverses to feed the paper back into the machine in order to print the second side of the page. 5.1.7 Waste Toner Collection Process Waste toner on the OPC drum and on the image transfer belt is collected into the waste toner tank.
System Outline 5.2 Outline of Engine Firmware The CLP 510/510N use 4 different colored toners (Yellow, Magenta, Cyan, Black) and it is a laser color printer. Engine firmware controls the print processes, driving the print engine, paper feed, developer, fuser, and paper discharge systems. It has both color and mono printing modes.
System Outline 5.2.1 System Initialization The system initialization process is carried out immediately after power on. The following tasks are performed. 1) Initialize ASIC 2) Initialize system variables 3) Initialize a virtual timer 4) Initialize fuser control 5) Initialize ADC 6) Set-up ITB HOME interrupt 5.2.2 Warm-Up In the warm-up stage, the following tasks are performed.
System Outline 5.2.3 Ready 1) Host interface is monitored for print commands 2) Heat control * Target temperature (165°C) * Every 40 seconds, temperature value for the previous 250ms is read and a proportional control process is carried out 3) This is the standby mode entered after warm-up or after completing a print job.
System Outline 5.2.5 Print After sensing the ITB home position the following tasks are performed, Send Psync signal to controller -> Operates virtual timer for each color(Vdata) -> Forms latent image on OPC drum -> Supplies toner on OPC drum -> Transfers image to ITB (T1 ) -> Pickups a paper -> Transfers image to a paper (T2) 1)Check ITB Home (Treated by Home interrupt): It is designed to detect ITB HOME every 3 seconds. a) ITB Home sensing b) If a test mode is set up, a test pattern is printed.
