CHAPTER 2 EXPLANATION OF OPERATION I. ELECTROPHOTOGRAPHIC PROCESSING MECHANISM............ 2-1 II. PRINTING PROCESS.......................
CHAPTER 2 I. EXPLANATION OF OPERATION ELECTROPHOTOGRAPHIC PROCESSING MECHANISM (1) Electrophotographic process The electrophotographic process is explained briefly below: 1. Charging A voltage is applied to the CH roller to electrically charge the surface of the OPC drum. 2. Exposure The LED head radiates light onto the charged OPC drum in accordance with the image signal.
CHAPTER 2 2. EXPLANATION OF OPERATION Exposure The light emitted from the LED head is radiated onto the charged surface of the OPC drum. The charge of the radiated part of the OPC drum attenuates according to the intensity of the light, forming an electrostatic latent image on the OPC drum surface. LED head Charging roller Power Supply Unit LED head -- -- - - OPC drum Paper 3.
CHAPTER 2 4. EXPLANATION OF OPERATION Transfer A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the paper from its back side by the transfer roller. When a high voltage is applied to the transfer roller from the power source, the charge induced on the transfer roller moves on to the surface of the paper through the contact part between the transfer roller and the paper, the toner being attracted to the paper surface from the OPC drum surface.
CHAPTER 2 6. EXPLANATION OF OPERATION Removal of Electricity Electrically charge on the OPC drum surface decveases by exppsing the OPC drum surface after transfer to the light. Charging roller Board for the light of the removal of electricity Light for the removal of electricity OPC drum 7. Belt Cleaning Toner remaining on the transfer belt is scraped off by the belt cleaning blade and collected into the waste toner box of the transfer belt unit.
CHAPTER 2 8. EXPLANATION OF OPERATION Fuser The toner image which was transferred to the paper is applied heat and pressure as it passes between the heat roller and the backup roller, and it is therefore fused onto the paper. For the sake of safety, a thermostat is provided; it comes on to cut off the voltage supplied to the heater if the heat roller temperature rises above a certain preset temperature.
CHAPTER 2 II. EXPLANATION OF OPERATION PRINTING PROCESS The paper fed from Tray 1 or Tray 2 is carried by the paper feed roller, register roller L and transport roller. When the paper is fed from the MPT, it is carried by the MPT paper feed roller and register roller U. Then, an unfixed toner image is created on the paper transported onto the belt sequentially through the electrophotographic process of KYMC. Thereafter, the image is fixed under heat and pressure as the paper goes through the fuser unit.
CHAPTER 2 (1) EXPLANATION OF OPERATION Paper fed from 1st Tray 1. As illustrated in Figure 2-1, when the solenoid is ON, the register motor rotates (Counterclockwise turn), transporting the paper until the IN1 sensor comes ON. (When the solenoid is ON, the paper feed roller is driven.) 2. After causing the IN1 sensor to come ON, the paper is further carried over a certain distance to finally hit register roller L. (This corrects skew of the paper.) 3.
CHAPTER 2 EXPLANATION OF OPERATION (3) Transport belt 1. As the transport belt motor rotates in the direction of the arrow, the transport belt is driven. The belt unit consists of one transport roller placed immediately underneath each color drum, with a transport belt inserted in between them. As the specified voltage is applied, the transport belt and the transport rollers send the paper located on the transport belt to the fuser unit while transferring to it the toner image present on each color drum.
CHAPTER 2 (4) EXPLANATION OF OPERATION Up/down-motions of ID units 1. The up/down-motions of the ID units take place driven by the lift-up motor. 2. Figure 2-6 shows the motions of the different ID units when the printer is operated for color print. As the lift-up motor rotates (Clockwise turn), the lift-up link slides to the left, causing the ID units to come down, as can be seen in Figure 2-6. Namely, the printer is readied for color print. 3.
CHAPTER 2 (5) EXPLANATION OF OPERATION Fuser unit and paper output 1. As illustrated in Figure 2-8, the fuser unit and delivery roller are driven by the DC motor. As the fuser motor rotates (Counterclockwise turn), the heat roller is turned. This roller fixes a toner image by heat and pressure. 2. At the same time, the delivery roller rotates to output the paper.
CHAPTER 2 EXPLANATION OF OPERATION Outline of color drift correction The color drift correction is implemented reading the correction pattern that is printed on the belt with the sensor located inside the sensor shutter under the belt unit. This sensor is used to detect and correct the pattern.
CHAPTER 2 EXPLANATION OF OPERATION Error checking methods and remedial methods The color drift correction test function among the other self-diagnostic functions is employed to check errors. (page 4-21) Remedial methods against different errors • CALIBRATION (L or R), DYNAMICRANGE (L or R) Check 1: If the above indication appears, check the connected state of the sensor cable (FFC). If the connected state is found abnormal, restore it to the normal state.
CHAPTER 2 EXPLANATION OF OPERATION Outline of density correction method The density correction is implemented reading the correction pattern that is printed on the belt with the sensor located inside the sensor shutter under the belt unit. Automatic start timing of density correction: • If the environment at power-on is greatly different from the one in which previous print was executed. • If at least one or more of the four ID count values are close to those of a new product at power-on.
CHAPTER 2 EXPLANATION OF OPERATION Error checking methods and remedial methods The density correction test function among the other self-diagnostic functions is employed to check errors. (page 4-22) Remedial methods against different errors • CALIBRATION ERR, DENS SENSOR ERR Check 1: If the above indication appears, check the connected state of the sensor cable. If the connected state is found abnormal, restore it to the normal state.
CHAPTER 2 EXPLANATION OF OPERATION Principle of toner sensor detection Toner LOW is detected by the toner sensor (Reflection sensor) installed inside the printer. The shielding plate is mounted inside the ID and rotates in synchronization with toner agitation. Moreover, the ID has a shutter fitted. The shutter is synchronized with the operation lever of the toner cartridge, and the toner sensor can detect that the toner cartridge has been loaded properly.
