Page 57: Basic Structure Of The Printing System
1.1.2 Basic Structure of the Printing System A toner image is formed through the potential of the OPC belt varying in each of the charger, exposure, development, transfer and cleaning processes. Process of Print System (See Fig.4-9.) i) The OPC belt is biased to the voltage -CBV(V) by the power supply CBV. ii) A negative high voltage is applied to the charger unit by the power supply CHV, and a corona is generated as the result.
Page 58 Variation of OPC Belt Potential (See Fig.4-10.) i) The OPC belt is initially biased to -CBV(V). ii) The OPC belt surface is evenly charged to V (V) in the charging process. iii) The potential of the exposure part of the OPC belt is reduced to -VR(V) as it is exposed to the laser beam in the process of exposing, and an electrostatic latent image is formed on the OPC belt as the result.
Page 59: Details Of Each Process
1.1.3 Details of Each Process Charging The charging process ensures that the OPC belt is evenly charged by the charger system. Structure of the Charger Unit (Refer to Fig.4-8 and Fig.4-11) i) The charger unit is located as shown in Fig.4-8. ii) The charger unit consists of the case, corona wire and grid.
Page 60 Exposing The exposing process means that the OPC belt surface is exposed to the laser beam to form an electrostatic latent image. Structure of Scanner Unit i) The scanner unit is located as shown in Fig.4-8. ii) The source of the laser beam is a semiconductor laser. iii) The laser light is scanned onto the OPC belt by converting the laser light to a beam of light through the lens and reflective mirror to form an electrostatic latent image.
Page 61 Developing The developing process means that an electrostatic latent image on the OPC belt is made visible by depositing toner onto the exposed areas of the OPC belt. Structure of the Toner Cartridge (Refer to Fig.4-8 & 4.14.) i) The toner cartridge is located as shown in Fig.4-8. ii) Four toner cartridges are made available from the top to bottom in the order black, yellow, magenta and cyan.
Page 62 Developer roller Toner OPC Belt Fig.4-15 Toner (M) Exposing Developing Fig.4-16 IV-13...
Page 63 First Transfer (Drum) The first transfer process means that the toner image on the OPC belt is transferred onto the transfer drum. Structure of the Transfer Drum (Refer to Fig.4-8.) i) The drum is located as shown in Fig.4-8. ii) Material of the drum is aluminum. iii) Semiconductor rubber is used to provide the drum surface as shown in Fig.4- iv) The transfer drum rotates by contacting and synchronizing with the OPC belt.
Page 64 First Transfer Process (Refer to Fig.4-18.) i) The OPC belt has been through the development process and contacts and synchronizes with the transfer drum. ii) The OPC belt has been biased to the potential of -CBV(V). The potential of the transfer drum is nearly GND.
Page 65 Belt Discharging (Erase Lamp) The belt discharging process means that upon completion of the drum transfer process, an LED light is radiated onto the OPC belt prior to mechanically cleaning the belt to discharge the residual charge. Structure of Erase Lamp i) The erase lamp is located as shown in Fig.4-8.
Page 66 Belt Cleaning The belt cleaning process means that the residual toner adhering to the OPC belt surface is mechanically scavenged. Structure of Belt Cleaning The blade for the belt cleaning is located relative to the OPC belt cartridge as shown in Fig.4-8. Process of Belt Cleaning (Refer to Fig.4-20.) There is residual toner on the OPC belt as it has not been completely transferred in the drum transfer process.
Page 67 Second Transfer (Paper) The second transfer process is where the toner image on the transfer drum is transferred onto the transported paper. Second Transfer Structure i) The transfer roller for the paper transfer is located as shown in Fig.4-8. ii) The transfer roller is normally kept out of contact with the transfer drum until the second transfer process starts.
Page 68 Paper Discharging The paper discharging process is where the transported paper onto which the toner transfer has been completed is separated from the transfer drum by applying an AC charge to the paper. Structure of Paper Discharger (Refer to Fig.4-22.) i) The AC charger unit for discharge the paper is located as shown in Fig.4-8.
Page 69 Drum Cleaning The drum cleaning process is where the residual toner on the transfer drum is removed. Structure of Drum Cleaning (Refer to Fig.4-23.) i) The drum cleaning unit is located as shown in Fig.4-8. ii) The drum cleaning brush is a semiconductor type so that the brush can clean the surface of the rotating transfer drum.
Page 70: Scanning System
Scanning System This printer employs a semiconductor laser diode as a light source. This laser diode is switched according to the transmitted image data (video signal). The generated laser light scans over the OPC belt through a polygon mirror and lens, by which method electrostatic latent images will be formed on the OPC belt.
