The belt drive motor starts the reverse rotation to aligne the first original
against the left scale. Then the belt drive motor stops. As the feed-in clutch
stays off during this operation and the pull-out rollers have one-way bearings,
the second original stays where it is. Therefore, the distance between the first
and second originals becomes 3mm.
[Figure 4]
The belt drive motor starts the normal rotation to transport both the first and
second originals onto the exposure glass, keeping the same distance
between them. At the proper timing after the trailing edge of the second
original passes the registration sensor, the belt drive motor stops to place the
first and second originals on the exposure glass, as shown.
There is no adjustment for the combine 2 original mode. However, when the
lead edge registration is adjusted properly in the thin original mode, the lead
edge registration [A] in the combine 2 originals mode should be 0
±
2.5 mm
(0
±
0.1"). The distance [B] between the first and second originals is 3
±
3 mm
(0.12"
±
0.12"). This is fixed by the software.
