CHAPTER 2 FUNCTIONS & OPERATION
When a larger-sized document is skewed so
as to exceed the specified value, the ends of the
document may be torn. Therefore, the skew
detection sensors are mounted on both sides
inside the machine. The left-end sensor is
mounted on the left-end sensor PCB and the
right-end sensor is mounted on the right-end
sensor PCB. When skewing is detected by both
sensors, the document feeding is stopped.

6 Ultrasonic Double Feed Detection
Fig. 2-312 shows the double feed detection
mechanism by ultrasonic.
The double feed detection by ultrasonic uses
the ultrasonic (transmitting) sensor and the
ultrasonic (receiving) sensor.
The ultrasonic transmitting sensor is
connected to the ultrasonic drive PCB, while the
ultrasonic receiving sensor is connected to the
ultrasonic sensor PCB. The receiving sensor
receives the ultrasonic signal transmitted by the
transmitting sensor to gain a specific signal level.
When overlapping documents are fed, the signal
level is different from when properly feeding a
single document. The unit interprets this
difference as a double feed and displays an error.
Note:
When the length of the overlapping portion
of the documents is less than 50 mm, the
double feed may not be detected.
