MX-7040N  OPERATIONAL DESCRIPTIONS  13 – 22

Transport paper from each paper feed section to the registration roller with two or more transport rollers. The paper transport clutch controls
ON/OFF of each transport roller. The registration roller controls the relative positions of the transported paper and transfer images.

The registration roller controls the relative positions of the transported paper and transfer images. The registration roller is driven by the trans-
port motor. The relative positions of the paper and the transfer images are determined by the ON timing of the transport motor. 

PFM

Transport motor

Transports and drives the registration roller. 

PPD1

Registration pre-pre-detection

Detects the paper in front of transport roller 17.

PPD2

Registration pre-detection

Detects the paper in front of registration roller.

RRM

Registration motor

Drives the registration roller and controls ON/OFF.

 1

Transport roller 17 (Drive)

Transports paper from transport roller 13 to registration roller.

 2

Registration roller (Drive)

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

 3

Registration roller (Idle)

Apply a pressure to paper and the registration roller to provide the transport power of the transport roller to
