(3) Folding/saddle stitching mode
• Transmitting the FNS signal from the main body [1], the stacker entrance motor turns ON
and rotates in high speed.
• The stacker entrance motor rotates in low speed [2] to transfer the paper in low speed
when the stacker entrance sensor detects the trailing edge of the paper.
• The stacker entrance motor rotates in high speed and stands by for the subsequent
paper after a specified period of time since it rotates in low speed.
• The stacker entrance motor stops after completing the alignment operation [4] of the last
paper of the copy [3].
• The stacker entrance motor turns ON and rotates in high speed to stand by for the sub-
sequent paper when the folding paper exit sensor detects the trailing edge of the paper
bundle [5].
