MX-M1100  PAPER TRANSPORT SECTION  F – 3

The paper transport section serves the function of transferring
paper from each paper feed port to the registration roller section.
Paper from paper feed tray units 1 and 2, paper feed tray 3 and
paper feed tray 4 is transported vertically to the registration roller
section.
The detection of double-feed is done before transferring paper to
the registration roller, and the check of the off-center is carried out
by the image position sensor.
After the leading edge of the paper is synchronized with the leading
edge of the drum image in the registration roller section, the paper
that is transfer printed with the image in the transfer section passes
through the fusing section and is discharged either face-down or
face-up.

[Operation of Image position sensor]
It detects the position of the paper transferred by the contact image
sensor (CIS) and automatically adjusts the off center.
• CIS: Contact Image Sensor

It is a contact image sensor integrated with the light source, the
lens (Selfoc ) and the sensor.

Straight-Through Path (No Inversion, No Duplexing)

The paper transported from the each tray section is sent to the
paper exit roller (which is driven by the paper exit motor (POM))
with the transport roller). 

Invertion Path (Face-down Output, No Duplexing)

When face-down print is selected, the paper is passed under the
Face-up/face-down select gate. 
After paper passing, the paper exit gate guide falls down by its own
weight. 
When the specified time has passed from detection of the paper
lead edge by Face down reverse detection, Paper exit reverse
motor (SBRM) rotates reverse direction in the specified time. (The
rotation time differs depending on the paper size.)

The double-feed sensor is incorporated in the paper transport sec-
tion of 110/95 ppm machine, and it detects double feed.
Paper transport stops when double feed is detected.

Ultrasonic generator generates ultrasound during paper transport.
The level of reception of the ultrasonic sensor largely changes
(decreases) when double feed occurs. Double sheet feed is
detected in this method.

MX-M1100  PAPER TRANSPORT SECTION  F – 4

The sensor is composed of ultrasonic generator part and ultrasonic
detector part.  Double feed is detected using 220kHz ultrasound.
Operation when sheets of paper are normally fed one by one
Some of the ultrasound is reflected by the paper, but the ultrasound
reaches the sensor more than the specified level.
The sensor analog output level at that time is 300mV or more, and
digital output level is "L."
Operation when double feed occurs
Most of ultrasound is reflected when double feed occurs, because
the stiffness of paper is high.  As a result, the ultrasound which
reaches the sensor is weak, and less than the specified level.
At that time, the sensor analog output level is 300mV or less, the
digital output level is "H."
