MX-7001N DUPLEX SECTION H – 2
2. Operational descriptions
• Paper which had been sent from the fusing section is sent to the
paper exit roller 1 from the transport roller 13 that is driven by the
ADU motor upper.
At that time, paper passes under the gate guide.
ADU motor upper.
At that time, paper passes under the gate guide.
• After the specified time from detection of paper lead edge by
POD1, the paper exit drive motor is rotated forward, and after the
specified time, it is rotated reversely.
specified time, it is rotated reversely.
• The paper exit drive motor rotates reversely, paper is transported
to the reverse section. At that time, paper passes the right side of
the ADU gate guide by its own weight.
the ADU gate guide by its own weight.
• The transport roller 10 and the transport roller 11 that are driven
by the ADU motor lower transport the paper to the duplex paper
feed position.
feed position.
• Paper is stopped at the duplex paper feed position, and trans-
ported to the inside of the machine again.
