- Operation -
The DF operates in the combine two originals mode as follows:
Figure 1
The first original is fed in the same manner as in one-sided original
mode. When registration sensor-2 detects the trailing edge of the first
original, the feed-in and the belt drive motors stop once and the feed-in
clutch turns on again to prepare to feed in the second original.
Figure 2
As soon as the feed-in and the belt drive motor turn off, the belt drive
motor starts rotating in reverse to align the first original against the
original scale. Then the belt drive motor turns off.
Figure 3
50 ms after the feed-in motor turns off, the feed-in motor turns on again
at a lower speed (372 mm/) to feed the second original.
A few pulses (0 ∼ 14 pulses: depending on the settings of DIP switches
102-1 to 4) after the registration sensor-2 is activated by the leading
edge of the second original, the feed-in motor and the feed-in clutch turn
off.
