Signal Name
Description
/NO PRM
Signal from the Sensor Photo:Paper Set. This signal is Low when the Sensor Photo:Paper Set is
activated.
/SOLM
Control signal which activates the Solenoid Pick Up
/REG
Signal from the Sensor Photo:Regi. This signal is Low when the Sensor Photo:Regi is activated.
/REG CL
Control signal which activates the Clutch Regi
/TONER
Signal from the Toner Sensor. This signal is Low when the Toner Sensor is activated.
/EPRS
Signal from the Sensor Assy Exit ENV equipped on the ENV. This signal is Low when the Sensor
Assy Exit ENV is activated.
/NOPER
Signal from the Sensor Photo:No Paper equipped on the ENV. This signal is Low when the Sensor Photo:No Paper is activated.
SOLE
Control signal which activate the Clutch Elec equipped on the ENV
