  2-1 Mechanical Construction 2-1-1 Paper feed section Paper feed section consists of the paper feed unit that feeds paper from the paper cassette and the MP tray paper feed unit that feeds paper from the MP tray, and the paper feed conveying section that conveys the fed paper to the transfer/ separation section.

• Page 98
  (2) MP tray paper feed section The MP tray can contain about 100 pages. Feeding is performed by the rotation of the MP tray feed roller from the MP tray. Function of the MP tray friction pad prevents papers from multiple feeding. Figure 2-1-3 MP tray paper feed section MP tray paper feed roller Bottom plate…
• Page 99
  (3) Paper feed conveying section The conveying section consists of the parts shown in the following illustration and conveys papers from the paper cassette or the MP tray to the transfer/separation section when papers are fed. Paper by feeding or refeeding is conveyed by the middle feed roller to the position where the registration sensor is turned on, and then sent to the transfer/separation sec- tion by the upper registration roller and lower registration roller.

  2-1-4 Developing section (1) Developer unit The developing section consists of the developer unit and the toner container. The developer unit consists of the develop- ing roller where a magnetic brush is formed, the doctor blade and the agitator A and B that agitate the toner. Also, the toner sensor checks whether or not toner remains in the developer unit.

• Page 104
  2-1-5 Transfer/separation section (1) Transfer/separation section The image developed by toner on the drum is transferred onto the paper because of the electrical attraction between the toner itself and the transfer roller. The transfer roller is negatively biased so that the positively charged toner is attracted onto the paper while it is pinched by the drum and the transfer roller.

• Page 105: Cleaning Section

  2-1-6 Cleaning section After the transferring process, the drum needs to be physically cleaned of toner which is residual after the development process. The cleaning blade is constantly pressed against the drum and scrapes the residual toner off to the cleaning roller.

• Page 106
  2-1-7 Fuser section (1) Fuser unit The fuse section consists of the following parts and fixes the toner that is transferred to the paper at the transfer/separa- tion section. The paper sent from the transfer/separation section is interleaved between the heat roller and the press roller. The heat roller is heated by the fuser heater lamp installed inside, and the toner is fused by heat and pressure and fixed onto the paper because the press roller is pressed by the fuser press spring.

Initializing the developer unit (toner install mode) Description

>>Developer The new developer unit is shipped from the factory with no toner contained. The developer unit can be automatically replete with toner when a toner container is installed onto it and the printer is turned on. However, because the toner reservoir in the developer unit has a large capacity, it requires a lengthy period of time until a substantial amount of toner has been fed to get the printer ready. (A new developer unit needs approximately 200 g for triggering the sensor inside.)

Purpose

To execute when the developer unit has been replaced.

Method

1.Enter the maintenance mode [>>Developer].

2.Press the OK key. [>>Developer?] will be displayed.

3.Press the OK key. [Ready] will be displayed.

4.Turn off and on the printer. [Self test] [Please wait (Adding toner)] will displayed. The
