AR-RB1 DESCRIPTION OF OPERATION 4 - 6
(5) ADU delivery operation (AR-D19 the installed)
Table showing relation between the processing speed and the trans-
port speed in RB1
port speed in RB1
Unit: mm/s
Sensor input, motor output, solenoid output timing is as below.
Processing speed
The paper input motor and
upper turnover motor are
caused to turn in time with the
copier processing speed, thus
transporting the paper.

When the trailing edge of the paper
reaches a point 13mm from the copier
POD off, the transport speed in RB1
is accelerated.
