4) The copyboard cover is closed (at an angle of more than 5 deg but less than 30 deg)
Original sensor: Turns on and original size identification process 2 is performed.
F-4-20
5) The original cover is closed (at an angle of 5 deg or less)
The original size is identified.
Original sensor: Turns off.
In identifying the original size, the data obtained in the original size identification process 1 is compared with the data obtained in the original size identification
process 2 to check whether these two pieces of data are identical.
Note that a wrong original size may be identified because the sensor output level does not change in the following cases:
- When the original is A3-sized black
- When the original is a book (its thickness does not allow the copyboard cover to close fully, making it difficult to detect the sensor level change).
- When the copyboard cover is not closed fully (the sensor level change is not detected after lapse of the above time-out time)
F-4-21
Before original size identification processes 1 and 2 are performed, the original size is detected with original sensors as follows:
F-4-22
* For Chinese paper, the following sizes are detected:
8K:Equivalent to B4 size
16K:Equivalent to B5 size
