Reverse control

A. Switch-back mechanism
While in the double sided print, paper that passes through the reverse gate [3] is conveyed to the outside of the
main body by the reverse roller [5] and then sent back again to the inside of the main body. At this time, the
paper is guided to the conveyance roller /1 [1] side, not to the reverse gate side from the metal frame form of the
conveyance path. In this way, the paper is turned over to be conveyed to the registration section again through
ADU.
The ON/OFF timing of the reverse solenoid (SD3) that drives the reverse gate is controlled by the fusing exit sen-
sor (PS3) [2]. And the switchover between the normal rotation and the reverse rotation of the reverse motor (M6)
that drives the reverse roller is controlled by the reverse sensor (PS27) [4].
