B. When the paper length is 250mm or more (B5R or more)
(The paper input motor, upper turnover motor and lower turnover motor all operate.)
The paper input motor and
upper turnover motor are
caused to turn in time with the
copier processing speed, thus
transporting the paper.
The upper turnover motor and the
lower turnover motor are caused to
revolve in the paper delivery direction,
and the paper is discharged.
Transport speed
(high speed)
As for the relation between the process speed and the transport speed
in RB1, refer to the table (3)-A.
When the trailing edge of the paper
reaches a point 13mm from the copier
POD off, the transport speed in RB1
is accelerated.
Trailing edge of paper reaches
point 13mm from POD off
Processing speed
The lower reverse motor stops at
BPPD1 off, when the trailing edge of the
paper reaches a point 50mm before the
delivery roller, the transport speed
decreases.

AR-RB1 DESCRIPTION OF OPERATION 4 - 4
When the trailing edge of the
paper reaches the upper reverse
stop point, the upper turnover
motor and the lower turnover
motor stop.
Transport speed
(high speed)
After the trailing edge of the paper
passes the delivery roller, the
upper turnover motor stops.
