The paper exit gate is driven by SD103 (ADU gate solenoid).
The SD103 is controlled by the CB (control board) of the main
body.
1. Operation
a. Changing the paper exit gate
The paper exit guide is raised by SD103 (ADU gate sole-
noid) to feed the paper to the ADU when PS8 (paper exit PS)
is ON during the face side copying.
The paper exit guide is lowered due to OFF of SD103 when
the face side copying has been completed. The paper is
delivered to the exist tray after copying the back side.

Paper is fed from the LCT or PFU by transmitting the drive force
from M1 (main motor) to the paper feed roller using SD104 (LCT
solenoid) or SD105 (PFU paper feed solenoid). SD104 and
SD105 are controlled by the CB (control board) through ADUDB
(ADU drive board).
1. Operation
SD104 or SD105 is turned ON for specified period to feed
paper from the tray when the copy button is pressed. Paper
feed for the 2nd and after will start at a specified interval
from the previous paper feed ON.
2. Signal
a. Output signal
(1) SD104DRIVE (CB

This is the ON/OFF signal for SD104.
[L] : SD104 ON
[H] : SD104 OFF
(2) SD105DRIVE (CB
