Feeding sequence in two-sided copying mode
When the copier operates in two-sided copying mode, the copier pulls the out-
put back in for copying the second side.
When such an output returns from the Multitray to the copier, the Multitray's
feeding drive system must rotate in reverse of the copier; however, since the
Multitray is not designed to do so, the inlet roller roll pressure is released to let
the output (copy paper) slip off the roller.
