13.4 Feed drive system

13.4.1 Overview

Paper from the copier is sent to the finisher by the feed rollers. Feed rollers 1 and 2 are
driven by the finisher inlet motor (M1). The skew correction rollers, folding rollers A, B and
C, and folding roller 2 are driven by the folder motor (M71). The feed route of the paper is
changed by the ON/OFF switching of the inlet solenoid (SL5), according to the mode set on
the copier.
