2MF/2MG (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 1.
Page 198: Paper Conveying Section
2MF/2MG (3) Paper conveying section Paper 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 roller to the position where the registration sensor (RS) is turned on, and then sent to the transfer/separation section by the upper registration roller and lower registration roller.

2MF/2MG (2) Image scanner unit (ISU) The original image is illuminated by the LED and scanned by the CCD image sensor in the CCD PWB (CCD- PWB) via the four mirrors and ISU lens, the reflected light being converted to an electrical signal. If a document processor (DP) is used, the image scanner unit stops at the position of the DP contact glass and scans sequentially one row of the image on the original in synchronization with the moving timing of the original in the sub scan direction by driving the DP.

2MF/2MG (3) Laser scanner unit The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser beam is dispersed as the polygon motor (PM) revolves to reflect the laser beam over the drum. Various lenses and mirror are housed in the laser scanner unit, adjust the diameter of the laser beam, and focalize it at the drum surface.

Page 205: Developing Section
2MF/2MG 2-1-4 Developing section The latent image constituted on the drum is developed into a visible image. The developing roller contains a 3-pole (S-NS) magnet roller and an aluminum cylinder rotating around the magnet roller. Toner attracts to the magnet sleeve since it is powdery ink made of black resin bound to iron particles. Developing blade, magne- tized by magnet, is positioned approximately 0.3 mm above the magnet sleeve to constitute a smooth layer of toner in accordance with the magnet sleeve revolution.

Page 207: Transfer/Separation Section
2MF/2MG 2-1-5 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 208: Cleaning Section
2MF/2MG 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. The waste toner is collected at the output end of the sweep roller and sent to the waste toner box.

2MF/2MG 2-1-7 Fuser section The toner on the paper is molten and pressed into the paper as it passes between the heat roller and the press roller in the fuser unit. The heat roller has a fuser heater (FH) inside which continuously turns on and off by the fuser thermistor (FTH) to maintain the constant temperature onto the heat roller surface.
