(2) When paper reverse
Paper that has been conveyed is sent back by means of the reverse rotation of the ADU roller. At this
time, the switching sheet uses its own elastic power to block the conveyance path to the ADU convey-
ance roller/2, and the paper is conveyed to the loop roller of the tray 2. As a result, the paper is turned
inside out to be copied on the back side after passing through the same route as that for the paper
sent from the tray 2.
