AR-350/450 BASIC PAPER FEED SECTION 2-1
[2] PAPER FEED SECTION
1. Composition of paper feed section
2. Paper feed operation
A. Preliminary operation except for the manual feed tray
1)  Load paper and insert the tray, and the tray sensor will be turned on. 
2)  The lift-up motor rotates. 
3) The upper limit sensor turns on.
B. Paper feed operation
1) The take-up roller descends. 
2) The take-up roller rotates to feed paper.
3) At the same time the paper feed roller rotates to feed paper to the transport section.
4) At that time, the separation roller rotates to prevent against overlapped feed.

1
Take-up roller
Picks up paper and transports it to the paper feed roller.
2
Paper feed roller
Feed paper in the machine. 
3
Separation roller
Rotates simultaneously with the paper feed roller to prevent against overlapped feed.
For the manual feed tray, the separation pad is used instead of the roller. 
4
Paper upper limit sensor
Detects the top surface of paper and stops paper at the feed position. 
Except for BPT
5
Paper sensor
Detects paper presence. 
(Paper empty, upper limit detection: ON / Paper presence detection: OFF)
6
Paper width sensor
Detects the paper width in linkage with the paper guide.
Machine tray/MPT/
BPT
7
Paper length sensor PWB
Detects the paper length in linkage with the paper guide. For the manual feed tray, the 
paper guide is not attached and detection is made with the actuator. 
Except for BPT
8
Paper remaining quantity 
sensor
Detects the remaining quantity of paper in each tray. (3 steps + paper empty)
Except for BPT
9

3. Paper size detection
A. Paper width detection VR (MPT/BPT/Machine tray)
Width detection is performed by calculating the voltage (A/D conversion value) of the slide VR in linkage with the side guide plate. 
Paper width and paper size
(The range is set to Standard value ± 6 [mm].)
B. Paper length sensor (MPT/2nd and 3rd steps of 3-step paper feed desk)
Length detection is performed by combination of cassette size sensors 1 - 4.

C. Paper detection method of each tray
1) Machine 1st tray
Paper detection is performed by VR in linkage with both side guides. 
2)Multi-purpose tray
Paper detection is performed by VR in linkage with both side guides and the detector in linkage with the rear edge plate. 
 For the other than above, the paper size is considered as "Extra."
3) 2nd and 3rd steps of 3-step paper feed tray
Paper detection is performed by the detector in linkage with the rear edge plate. 
Paper size for automatic detection
4) Manual feed tray
Paper detection is performed by VR in linkage with both side guides and the detector on the tray.
