1

Paper exit roller (Drive)

Drives the roller in the paper exit section.   

2

Paper exit roller  (Idle)

Apply a pressure to paper and the paper exit roller to provide the transport power of the Paper pressure (idle) roller to 
paper.

3

Transport roller 4 (Drive)

Transports paper from the transport roller to the transport roller 5.

4

Transport roller 4 (Idle)

Apply a pressure to paper and the transport roller to provide the transport power of the Paper pressure (idle) roller to 
paper.

5

Transport roller 5 (Drive)

Lower duplex drive transport roller which transports paper to the registration rollers.

6

Transport roller 5 (Idle)

Transports paper to the Pressure (idle) Transport Roller. Paper is buckled between the Pressure (idle) Transport Roller 
and this roller to correct the paper skew and the relation between images and paper. 

7

Registration roller (Drive)

Registration Drive Roller that controls the transport timing of paper and adjusts the relative position between images on 
the Transfer Belt and the registered paper.

8

Registration roller (Idle)

Transports paper to the transfer section. / Controls the transport timing of paper and adjusts relative relations between 
the image and paper.

9

Paper Feed Roller

Feeds paper from the cassette to the Registration rollers.

10

Fuser heat roller

Fusing pressure roller

Flexible silicone-rubber pressure fusing roller.

12

Paper Feed Roller

Feeds paper to the paper transport section.

13

Separation roller 

Apply the pressure to the paper feed roller in reverse direction and prevents the paper from feeding it in layered condi-
tion.

14

Separation roller (Paper feed tray 1)
