Theory of Operation Ver. 5.0 May 2008
B. Stacker entrance transfer control
(1) Stapling mode (the paper size is not A4, B5, or 8
operation)
• 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 [3] when the stacker entrance sensor
detects the trailing edge of the paper and then the paper assist roller starts to rotate to
transfer the paper to the stacker in low speed.
• When the paper assist roller is driven, the paper assist motor and the paper assist sole-
noid operate to assist the stacking operation.
• 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.
• After the last paper of the copy passes, the stacker entrance motor stops when the sta-
pling operation is started [5].
• The stacker entrance motor turns ON [6] and rotates in high speed to stand by for the
subsequent paper when the paper exit motor completes the closing operation.
