OCT STACK SENSOR, OCT HOME SENSOR, OCT EXIT SENSOR, OCT DIRECTION SOLENOID,
OCT MOTOR, AND OCT OFFSET MOTOR
Signal Name
Function
/OCT PRES
Signal for detecting the presence of optional OCT (LOW level
when installed, and HIGH level when not installed)
FULLSTK SNR
(OCT)
Signal for monitoring the amount of paper ejected on the OCT
tray (LOW level when not full, and HIGH level when full)
/OCT HOME SNR
Signal for detecting the home position of the Offset Motor (LOW
level at the home position, and HIGH level not at the home
position)
/OFFSET MOT ON
Signal for switching on and off the Paper Offset Motor (LOW
level when switching on and HIGH level when switching off)
/OCT FORWARD
Signal for switching the direction of rotation of the Paper Offset
Motor (LOW level for the offsetting (forward) direction, and
HIGH level for the return direction)
/OCT MOT ON
Signal for switching on and off the OCT Motor (LOW level when
switching on and HIGH level when switching Off)
/DIRECT SOL
Signal for switching the direction of paper ejection (LOW level
to the standard tray and HIGH level to the optional unit)
/OCT EXIT SNR/MB
PRES
Signal for monitoring paper when OCT is installed (LOW level
when paper is present, and HIGH level when paper is not
present)
Signal for detecting the presence of optional Mail Box when
OCT is not installed (LOW level when Mail Box is installed, and
HIGH level when not installed)
RXD M/B
Signal for communication between ESS and Mail Box
TXD M/B
Signal for communication between ESS and Mail Box
