PAPER MISFEED DETECTION
2-15
Detailed
Descriptions
J1: The leading edge of the original does not reach the feed sensor within the time
required for feeding the distance between the pick-up roller and the feed sensor
+ 150 mm after the pick-up clutch turned on.
J2: The leading edge of the original does not reach the read sensor within the time
required for feeding the distance between the feed sensor and the read sensor
+ 150 mm after the feed sensor was activated.
J3: The leading edge of the original does not reach the feed-out sensor within the
time required for feeding the distance between the read sensor and the feed
out 30 mm after the read sensor was activated.
J4: The trailing edge of the original does not pass through the feed sensor within
the time required for feeding the maximum original length (2 m) + 60 mm after
the feed sensor was activated.
J5: The trailing edge of the original does not pass through the read sensor within
the time required for feeding the or 75 mm after the read was activated.
J6: The trailing edge of the original does not pass through the feed-out sensor
within the time required for feeding the original 75 mm after the feed-
out sensor was activated.
If an original jam or an original non-feed is detected, the paper transport motor,
paper feed motor, and the exposure lamp turn off. Then, the appropriate LEDs
inform the user of the machine’s status.
If an original remains in the ADF, the original is fed out and the paper transport
motor stops.
