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.

2-1-2 (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.

2-1-3 (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.

(1) 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 dis-
persed as the polygon motor 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.

2-1-4  Developing section
(1) Developing section
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.

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.

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 drum screw and sent to the waste toner box.
After the drum is physically cleaned, it then must be cleaned to the electrically neutral state. This is necessary to...

(1) Fuser unit
The fuser 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...
