[EXTRA] Operates on the paper size set by the user program.
The remaining paper quantity is calculated from the rpm of the lift mo-
tor from when the lift position sensor detects the lift plate lower limit
position to when the paper upper limit detector detects the paper up-
per limit.

(2) Manual paper feed section operation (AR-C150 only)
The pickup roller moves up and down to press the paper surface to
separate the top paper, which is sent to the paper feed roller.
The paper feed roller sends the paper to the transport section. The
separation roller and the paper stopper prevent against double feed.
The pickup roller and the paper stopper are moved up and down by
the pickup clutch solenoid. ON/OFF control of the pickup roller and
the paper feed roller is made by the paper. The paper is sent to the
resist roller by the manual paper transport roller.

The paper size is detected by the paper length detector and the paper
width detector.
The paper width sensor is of the variable resistor type. It detects the
paper width by detecting the resistance which varies according to the
paper guide position.

The paper width sensor is of the variable resistor type. It detects the
paper width by detecting the resistance which varies according to the
paper guide position.
The tray position detector detects that the paper tray is set in the
max. length position or in the min. length position.
When the paper tray is set in the max. length position, the paper
length detector is forcibly turned on. It is identified by the tray position
detector.

(3) Paper transport section
In this section, the paper fed from the paper feed section is trans-
ported to the transfer section (resist roller) by two or more transport
rollers.
ON/OFF control of the transport rollers is made by the paper transport
clutch.

(4) Paper resist section
The resist roller controls the relative positions of the transported pa-
per and the transfer images.
The resist roller is driven by the resist roller motor.
The relative positions of the paper and the transfer images are deter-
mined by the ON timing of the resist roller motor.
