Up/down control

For the up/down of the tray, when the paper lift motors /Up (M8) [1] and /Lw (M9) [7] rotate in the normal and
reverse directions, the lift arms /Up [11] and /Lw [9] start up to bring up and down the PI lift plates /Up [12] and
/Lw [10]. The lower limit position is detected by the PI lift plate home sensors /Up (PS34) [2] and /Lw (PS40) [8].
The upper limit position is detected by the PI upper limit sensors /Up (PS32) [4] and /Lw (PS38) [6] at the posi-
tion to which the actuators /Up [3] and /Lw [5] are pushed up by the PI lift plate.
When the PI paper set sensors /Up (PS44) and /Lw (PS45) are ON with the main body start button ON, M8 and
M9 turn ON to bring up the PI lift plate. When PS32 and PS38 turn ON, M8 and M9 stop.
While in the copy/print operation, when PS32 and PS38 turn OFF from ON, M8 and M9 turn ON again to bring
up the plate until PS32 and PS38 turn ON.
When PS44 and PS45 turn OFF with no paper left, M8 and M9 make a reverse rotation to move down the PI lift
plate until PS34 and PS40 turn ON.
