MX-3114N OPERATIONAL DESCRIPTIONS 13 – 7
B. Operational descriptions
(1) Paper feed operation
The pickup roller moves up and down to press the paper surface, separating the paper on the top of the paper bundle and sending it to the
paper feed roller section.
The paper feed roller feeds paper to the transport section to prevent against double feed with the separation roller. The manual paper feed
clutch controls ON/OFF of the pickup roller and the paper feed roller. Paper is sent to the registration roller by the manual transport roller.
(2) Paper size detection
The paper size is detected by the combination of the following detectors on the manual paper feed tray.

CPFM Paper feed motor Drives the paper feed section.
HUD_M/TH_M Temperature/humidity sensor Detects the temperature and the humidity. (For the process control)
MPED Paper empty sensor (Manual paper feed tray) Detects presence of paper. (Manual paper feed tray)
MPFS Paper feed solenoid (Manual paper feed) Controls the paper feed roller. (Manual paper feed)
MPLD Paper length detector (Manual paper feed tray) Detects the paper length. (Manual paper feed tray)
MPWS Paper width detector (Manual paper feed tray) Detects the paper width. (Manual paper feed tray)
PFM Transport motor Drives the transport rollers 5 and 9.
No. Name Function/Operation
1 Paper feed roller (Manual paper feed tray) Feeds paper to the paper transport section.
2 Separation roller (Manual paper feed tray) Separates paper to prevent double-feeding.
3 Transport roller 9 (Idle) Apply a pressure to paper and the transport roller to provide the transport power of the
transport roller to paper.
4 Transport roller 9 (Drive) Transports paper transported from transport roller 10 to transport roller 5
5 Transport roller 10 (Drive) Transports paper from manual paper feed section to the transport roller 9.
6 Transport roller 10 (Idle) Apply a pressure to paper and the transport roller to provide the transport power of the
transport roller to paper.
