MX-ST10  OPERATIONAL DESCRIPTIONS  3 - 3
5.  Bypass feed out
(1) Outline of paper feed out operation
Transported paper is fed out to the top side by the path gate solenoid 1 (SL01) immediately after the entrance roller, and fed out to the
bypath by the path gate solenoid 2 (SL02).
(2) Feed out motor start timing
The feed motor is started after reception of the paper attribute data.
(3) Feed out motor stop timing
The feed out motor is stopped when there is no paper in stacker after reception of the STANDBY signal from the main machine. 
The feed motor stops when next paper is not detected by the entrance sensor within 1000msec from detection of paper by the bypass exit
sensor.
6.  Alignment operation stacker exit roller offset control
Before discharging paper to the stack tray, the stack exit roller is shifted.
Initial operation
The home position is 2mm shifted from when turning ON the offset home sensor for every discharge in the offset home sensor direction.
If the series of operations will not be terminated within 350msec, it is judged as an abnormality. After completion of the series of opera-
tions, the roller is shifted to the shift standby position.
Operation in paper pass
The initial operation is executed by a job start in the stack mode. When paper passes the entrance sensor, the offset operation is started.
The offset return operation is executed in 100msec after paper has passed the stack path exit sensor.
