2. ADF Being Opened
No.1 mirror base: moves to a specific point of original detection
scanning lamp: off
original sensor: off
F-5-33
3. ADF Being Closed
No. 1 mirror base: at point of original detection
scanning lamp: off -> on
original sensor: original detection operation
- When the ADF is at 25 deg or lower, the external light within the width of any original is kept out of
external light, thus causing the machine to assume the absence of an original at points of external light
detection (external light search operation).
The ADF open/closed sensor 2 identifies the state as being "closed," and the machine starts original size
detection.
Here, B5, B4, A4, and A3 are eliminated from the list of possible sizes.
- When the external light search is over, the machine turns on the xenon lamp for the main scanning lamp,
and checks the CCD (4 points) for external light. For sub scanning direction, the machine starts to
operate the original sensor.
F-5-34
4. ADF Fully Closed (5 deg or less)
No. 1 mirror base: at point of original detection
scanning lamp: on
original sensor: original detection operation
The machine looks for a change in the output level of individual sensors for a period of 2 sec after the
ADF open/closed sensor 1 has identified the current state as being "closed." The absence of a change in
the level causes the machine to assume the presence of an original at the point in question.
The machine uses the combination of changes in the levels of 5 points to identify the size of the original
in question.
