4.4 Paper Jam Detection The printer has a registration sensor and a paper eject sensor at the paper outlet to detect whether the printed paper has been fed correctly. A paper jam is detected by whether the paper is present at the sensor at the check periods programmed in the engine CPU memory. If the engine CPU detects a paper jam, the main motor, paper feed motor and scanner motor is turned off immediately and the jam status is transmitted to the video controller circuit. A paper jam is detected in any of following conditions: 1) Paper exists at the paper ejection sensor or the registration sensor when power is switched on. (JAM REAR or JAM INSIDE) 2) Paper has not reached the registration sensor within a specified time (JAM TRAYS). 3) Printed paper has not passed through the registration sensor within a specified time (JAM INSIDE (1) ). 4) Printed paper has not reached the paper ejection sensor within a specified time (JAM INSIDE (2) ). 5) Printed paper has not passed through the paper ejection sensor within a specified time (JAM REAR).
