Signal names for Engine Board <−> Solenoid T1/MPF, Sensor LP/MPF NP/FDR LP/FDR NP,
Clutch Turn, SW DX2 and PWBA Size MPF route
* The feeder assembly option 250 or 500 mounted just under the base engine is called feeder 2.
** The feeder assembly option 250 or 500 mounted just under the feeder 2 is called feeder 3.
Signal name Explanation
/FEED1 ON A solenoid T1 control signal. When this signal is set low, the solenoid T1 (feed
solenoid of feeder 1) is activated; otherwise, the solenoid T1 is released.
/FEED MPF ON Solenoid MPF control signal. When this signal is set low, the solenoid MS (feed
solenoid of MPF) is activated; otherwise, the solenoid MPF is released.
NO PAPER MPF A signal sent from the sensor MPF NP (no paper sensor of the MPF).
This signal is set low when the sensor MPF NP receives the light.
FEEDER CLK A clock signal for PWBA feeder.
FEEDER STATUS A data signal sent from the PWBA feeder to the controller board.
FEEDER LOAD A data request signal sent from the engine board to the PWBA feeder.
FEED2 A solenoid assembly optional activation instruction signal for feeder 2
*
TURN2 A clutch option feeder activation instruction signal for feeder 2.
FEED3 A solenoid assembly option activation instruction signal for feeder 3
**
TURN3 A clutch option feeder activation instruction signal for feeder 3.
NO CASSETTE1 A signal sent from the SW DX2 (cassette sensor switch of feeder 1). This signal
is set low when the cassette assembly 250 is mounted correctly.
NO PAPER1 A signal sent from the sensor FDR NP (no paper sensor of feeder 1). This sig-
nal is set low when the sensor FDR NP receives the light.
/DUP CLUTCH ON A clutch turn control signal. When this signal is set low, the clutch turn (clutch for
feeding paper from the duplex unit) is activated; otherwise, the clutch turn is
released.
