  8. Ⅰ. General Specification Review CLP-310N is Color Laser Printer and its print speed is 4(C)/16(M) ppm(A4).

  9. Ⅱ. Process Objectives • Understanding the basic structures and operating principle of each parts • Studying the printing process and electronic photo process • Comprehension of System Layout

  10. Electronic Photo Process

  11. Ⅱ. Process System Layout (CLP-300 / CLP-350N) Paper Input (Cassette) LSU (Laser Scanning Unit) 2 1 2nd Transfer Roller Fuser 4 3 ITB (Intermediate Transfer Belt) 1st Transfer Roller 6 5 OPC (Organic Photo Conductor) Developers (Y, M, C, & K) 8 7 Toner Kits (Y, M, C, & K) 9

  12. Ⅱ. Process 4 6 5 8 7 3 2 1 System Layout (CLP-310N) Paper Input (Cassette) LSU (Laser Scanning Unit) 2 1 2nd Transfer Roller Fuser 4 3 ITB (Intermediate Transfer Belt) 1st Transfer Roller 6 5 OPC (Organic Photo Conductor) 8 Toner Kits (Y, M, C, & K) 7

  13. Ⅱ. Process System Layout 1. Cassette Feeding Method : Cassette Type Feeding Standard : Center Loading Feeding Capacity : Cassette 150 Sheets(75g/㎡, 20lb Paper Standard) No Manual Feeder Paper Detecting Sensor : Photo Sensor (Empty, Registration, Exit) Paper Size Sensor : None

  14. Ⅱ. Process System Layout 2. LSU (Laser Scan Unit) Consisted of LD(Laser Diode) and Polygon Motor Control. Error Phenomenon Polygon Motor Error The Rotation of Polygon Motor can not reach stable. Hsync Error Though the rotation of Polygon Motor reach stable, the signal of Hsync is not occurred.

  15. Ⅱ. Process System Layout 3. 2nd Transfer Ass’y The life span: Print over 100,000 sheets (in 15~30 ℃)

  16. Ⅱ. Process System Layout 4. Fuser Ass’y Heat Lamp : Similar toCLP-300 series Heat Roller : Similar toCLP-300 series 2 Pressure Roller : Similar toCLP-300 series Thermistor : Temperature-Measuring Device Thermostat : Critical Temperature-Detecting Device

  17. Ⅱ. Process System Layout 5&6. ITB (Intermediate Transfer Belt) & 1st Transfer Roller The life span : Print over 100,000 Images The ITB unit includes 1st Transfer Roller

  18. Ⅱ. Process System Layout 7. OPC (Organic Photo-Conductor) The life span: Print over 24,000 Images

  19. Ⅱ. Process System Layout 8. Toner Kits The life span: Color → 1000 images (Standard Coverage Print-Out) Black → 1500 images (Standard Coverage Print-Out)

  20. Ⅱ. Process System Layout 9. Driver Ass’y Power is delivered by gearing of Drive Ass’y. By driving the motor, it supplies the power to the feeding unit, the fusing unit, and the distributing unit. Main Motor is similar to BigBang Main Motor.

  21. Ⅱ. Process Review • What is the function of Paper-sensor? • How long is the life of Transfer Roller? • What is the function of Thermistor and Thermostat?

  22. Ⅲ. Disassembly Objectives • Practicing the skill of disassembly and assembly. • Understanding the basic structures of major part.

  34. Ⅲ. Disassembly Review • Can you disassemble and assemble CLP-310N?

  35. Ⅳ. Troubleshooting Objectives • Building ability to deal with various problems raised in the field by reviewing troubleshooting. • Check the solution of each problem. • Check the difference of each Jam.

  36. Ⅳ. Troubleshooting Printing Problems – Causes and Solutions

  37. Double Feed Occurred the double feed 1. Check that Cassette Locking is right position. 2. Check that papers are properly installed and held in paper tray. Check the condition of Rubber-Pick NO YES YES if worn out the rubber, replace Rubber-Pickup, if contaminated rubber, clean up the rubber with alcohol or replace Adjust the Cassette/papers to the right position NO NG OK Re- printing OK/NG? End Re- printing OK/NG? NG OK 1. Check the position of Pad-Friction. 2. Check up and down movement of Holder-Pad. 3. Check assembly condition of Housing-Pick Up. End YES NO Adjust or replace the parts NG Re- printing OK/NG? Replace the paper tray assembly OK End
