AR-LC5  OPERATIONAL DESCRIPTIONS  5 - 1

When the machine power is turned on, if the tray is on the open/close
allow position (the lower limit sensor: LDD ON position), the lift motor is
turned on to lift the tray and stop it at the paper feed position (upper
limit sensor: LUD ON position).

When the machine power is turned on, if the tray is on the paper feed
position, lifting is not performed.

When the tray is stationary at the paper feed position, if the tray lift-
down SW is pressed, the tray moves down. 

When the tray stops at the open/close allow position, the tray can be
opened/closed.

When the tray is stationary at the paper feed position, the LED lights
up. When the tray is lifting up or down, the LED flashes. When the tray
is stationary at the lower limit position (where the tray can be opened/
closed), the LED turns off.
