1.5.3 Original transport process
SADF mode
In the SADF mode, the original is set with the image side
down and transported from right to left.
ADF and RDH modes
There are two copy modes: sort and stack. In the stack
mode copies of the same page are grouped together.
When this mode is selected with user tool [10], the
originals set in the stack original feed table of the RDH
are fed and copied then returned to the table just once
(ADF mode).
On the other hand, in the sort mode the copies are
assembled as sets in sequential order. This mode is
always selected when originals are set in the stack feed
table of the RDH, except when the stack mode is
selected. In this mode, the RDH performs the original
recirculating motion (RDH mode).
The following explains the differences in original and
copy paper motions when simplex or duplex copies are
made from the simplex or duplex originals in the sort and
stack modes.
ADF mode (stack mode)
Simplex original to simplex copy or duplex copy mode
In these modes, the original is set with the image side
down and transported as shown. The original is stopped
on the exposure glass for exposure.
Following exposure, the original is sent to the reversing
unit. In the reversing unit, the original switches back and
then returns with the image side down to the original
table.
Before the original feeding starts, the recycle arm is
placed on top of the original stack. The copied originals
are returned and stacked on the recycle arm. When all
originals are fed once, the recycle arm falls on the
bottom of the original table. The recycle arm is detected
by a sensor and the copier detects the end of the
original feeding cycle.
