  • Page 20: Operations

    2. 2 Operations 1.Sheet Bypass 1)Construction of the sheet bypass • Sheet bypass consists of a sheet bypass paper feed unit and a registration roller unit. Component name Description Sheet bypass paper feed Feed the paper from the sheet bypass pick up roller roller to the registration roller.
  • Page 21 2)Operation of the sheet bypass paper feed unit • When starting copying with the sheet bypass selected, the rotation of the main motor is transmitted to the transmission gear via drive gears and to the registration roller gear in the sheet bypass paper feed unit. The rotation of the registration roller gear is transmitted to the sheet bypass solenoid via middle roller.

  • Page 22: Paper Feed Unit

    4)Sheet bypass paper size detection • The paper size detecting micro switchs are attached to the sheet bypass and detect the paper size. Micro switchs 2.Paper Feed Unit 1)Construction of the paper feed unit • The composition is as follows. Component name Description Paper feed roller...
  • Page 23 2)Operation of the paper feed tray • The paper tray sensor detects the paper tray is properly postioned in the copier. • The spring under the bottom plate of the tray then lifts paper. • With the Start key, the main motor starts rotating and transmits the rotation to the middle gear via drive gears.

  • Page 24: Toner Cartridge

    3.Toner Cartridge 1)Construction of the Toner Cartridge • The developer unit consists of the magnet roller, agitator 1 and agitator 2. • Toner is mixed by the agitator 1 and 2, then transported onto the developer sleeve. Toner on the developer sleeve adheres to the electrostatic latent image on the drum by AC bias for development.
  • Page 25 2)Driving developer • The rotation of the main motor is transmitted to the developer drive gear via some gears. The developer unit is connected to the machine with gears and linked with the mixing mill gear and transport screw gear to mix and transport toner. The transport screw coupling is linked with the waste toner screw to collect waste toner.
  • Page 26 3)Cleaning drum • The toner remaining on the drum is scraped off by the cleaning blade after the development and transfer. • The cleaning blade is fixed and pressed on the drum surface to remove the toner on the surface. •...

  • Page 27: Fuser Unit

    4.Fuser Unit 1)Construction of the fuser unit • The composition is as follows. Component name Description Heat roller Fuse toner onto paper by heat. (Aluminum + Teflon coating) Pressure roller Fuse toner onto paper by pressing paper to the heat roller.
  • Page 28 2)Fusing The heat roller and the pressure roller in the fuser unit melt toner onto the paper using a combination of heat and pressure. • The upper heat roller has a Teflon coating on the aluminum surface, which allows toner easily to be released from the surface. The ruggedness enhancement and antistatic prevention processing are used in making the heat roller.
  • Page 29 3)Driving the fuser unit • The rotation of the main motor is transmitted to the heat roller gear via some gears. • The paper exit sensor lever detects the paper exiting the fuser unit. 4)Fusing the temperature The heat roller has a halogen lamp that lights up while warming up and making copies.

  • Page 30: Optics Unit

    5.Optics Unit 1)Construction of the optics unit • The optics unit consists of the exposure (fluorescent) lamp, the lens, the CCD sensor and the reflecting mirrors. • The optics motor moves the full-speed unit exposing the original with the exposure lamp. The reflection from the original is gathered on the CCD image sensor via lens, where optics signals can be converted into electrical signals.
  • Page 31 2)Photoelectric conversion • Photoelectric conversion is to convert optical signals into electrical signals. Pixel used for photoelectric conversion is called “photoelectric converted pixel”. The linear type of CCD image sensor for B/W is used here. 3)CCD sensor The CCD image sensor consists of the photo acceptance unit, transfer unit and output unit.
  • Page 32 5)Driving the optics unit • The optics unit (full-speed and half speed unit) is driven by the optics unit motor. Its rotation is transmitted to the full-speed and half-speed unit via optics drive belt, optics drive pulley, full-speed unit drive wire and half-speed unit drive wire. •...
