■ Jam Detection
Jam is detected by the Document End Sensor.
• In the case of SADF: SADF Document End Sensor (PS8)
• In the case of DADF: DADF Document End Sensor (PS6)
In the case of SADF
In the case of DADF
Occurrence of a jam is judged by whether paper is in the sensor area at the timings stored in the DC Controller.
When the DC Controller judged the Jam has occurred, printing operation is stopped and the occurrence of the jam is notified to
the Main controller at the same time.
"Paper jammed." is displayed on the screen of the Control Panel.
In the case of models with FAX function, alarming sound beeps when the jam is detected.
