Service Manual

 

PFM

Transport motor

Drives transport between the resist roller and the paper feed section, 
transport between the resist roller and the right door section.

PPD1

Resist pre-detection

Detects the paper in front of resist roller.

PPD1

Resist detection

Detects the paper in rear of resist roller.

RRM

Resist motor

Drives the resist roller and controls ON/OFF.

1

Resist roller (drive)

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

2

Resist roller (idle)

Applies a pressure to paper and the resist roller to give paper the transport 
power of the transport roller.

3

Transport roller 8 (drive)

Transports the paper to resist roller.

MX-4101N  PAPER TRANSPORT SECTION  G – 2

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

1)

Remove the developing unit (K).

2)

3)

Remove the primary transfer unit. 

4)

Remove the tray paper feed unit 1.

5)

Remove the rear cabinet.

6)

Remove the ADU connection drive.

7)
