MX-M700N DUPLEX SECTION H – 2
2. Operational descriptions
A. Outline
When duplex print is selected, paper one surface of which was
printed is switched back to feed to the duplex section to make
duplex print.
B. Paper transport operation in duplex print
(1)
Switchback operation and transport to the reverse
section
1)
The paper transported from the fusing section is sent to the
paper exit roller 1 (which is driven by the paper exit motor 2
(POM2)) with the transport roller 16 (which is driven by the
paper exit motor 1 (POM1)).
At this time, paper is passed under the paper exit guide. After
paper passing, the paper exit gate guide falls down by its own
weight.
